2. State of the Art of Solar Thermal Applications
Solar heating for open-air swimming pools have been used for several decades
now and are a well- established technology. However, this does not mean that
this application of solar thermal energy has reached its limits yet.
According to statistics in Sun in Action II, about 3-4.000 m2 of unglazed
collectors have been placed yearly in the 90’s. The estimated production and
sales for 2000 and 2001 is 10.000 m2 yearly.
If we look at the developments over recent years, heating of the pool is too
costly for most swimming pool owners. Existing older conventional heating
systems are however often replaced either by absorber systems or the owners
do without heating altogether.

2.1 Absorber Systems
Systems without auxiliary heating
Solar circuits in public open-air baths are normally operated with a separate solar
circuit or absorber circuit pump. The hydraulic construction is much more
complex than for private swimming pools because of the hygiene requirements.
A system in a large open-air pool functions according to the following principle:
The wastewater is led from the pool into a central water storage tank. This tank
acts as a “water level display” for the whole swimming pool water circuit.
Evaporated water is replaced here by fresh water. The water is pumped through
the filter from the water tank. One (or according to the design of the filter
system) several parallel-connected filter pumps are responsible for this. After
this the water is returned to the pool via the water treatment system.
Figure 2: Circuit diagram of open air swimming pool heating by solar absorber
field
Integration of auxiliary heating
Conventionally operated auxiliary heating is necessary if the pool water has to be
maintained at a constant temperature. Some open-air pools wish to offer their
visitors warm swimming pool water independently of the sunshine, which
requires auxiliary heating when the solar radiation is insufficient.

(DGS, 2008)
Unglazed absorbers
Solar open-air pool heating uses absorbers to collect the energy. The collector
design is characterized by the lack of transparent cover and housing as well as
thermal insulation. This simple construction is possible since the systems operate
with low temperature differences between the absorber and the surroundings
and with relatively uniform return temperatures (10°C – 18°C). The swimming
pool absorber is always made from plastic. The use of unglazed and un-insulated
absorbers for solar open-air pool water heating has some advantages due to the
special operating conditions:
In the typical operating range, with a temperature difference Δϑ between the
outside temperature and the mean absorber temperature of 0-20 K, absorbers
often operate with a higher efficiency than glazed collectors. This can be
explained by the fact that the optical losses (normally about 10 to 15% with
respect to the amount of solar radiation) through a transparent cover do not
arise and that the thermal losses are not so significant because of the low
temperature difference Δϑ. These thermal losses increase with operating
temperatures, which however rarely occur due to the moderate absorber
temperatures found under normal operating conditions. The wind speed is the
decisive factor, which causes losses and hence has a negative effect on the
absorber efficiency. This was established in an investigation of absorber testing
and test results of solar open-air pool heating.

Apart from a few special designs plastic absorbers can be subdivided into two
groups:
• Tube absorbers (small tube absorbers)
• Flat absorbers
The tube absorber is the simplest design. A number of smooth or ribbed tubes
(small tubes) are arranged in parallel and according to the design are connected
together with intermediate webs or by retainers at a given spacing. Absorber
lengths of up to 100 m can be achieved and obstructions like chimneys or
rooflights can easily be circumvented.
In the case of flat absorbers, sometimes also called plate or cushion absorbers,
the channels are linked together structurally. This produces plates of different
dimensions with a smooth surface. This has the advantage that there are no
grooves in which dirt or leaves can accumulate and solidify. The self-cleaning
effect during rain is also better. The influence of the design form on the
conversion factor with different inclination angles can be measured but it is
minimal. Variations of the angle of incidence lead to small differences in the
conversion factor only for flat collectors. In the case of ribbed tube absorbers
they lead to larger variations than with normal tube absorbers.
All absorbers are very easy to handle (see also the installation chapter), thus for
example all common types can be walked on. The following figures show a
summary of the absorbers available on the market and the different methods of
connecting the absorber to the collecting and distributing pipes.

Solar absorbers are exclusively made from plastic. They can be hard and rigid or
soft and flexible according to the plastic mixture. The use of plastic permits
operation of the solar system with chlorinated swimming pool water. It is
however necessary to consider the chlorine content. A high dose (from about 5
mg/l) can damage the absorber. The exact limits, from which damage can occur,
depend on the plastic composition.
Plastics are also used for pipelines. These are however made from rigid
materials. The following plastics are basically the ones that can be used:
EPDM Ethyl Propylene Diene Monomer
PP Polypropylene
PE Polyethylene
ABS Acrylnitrile Butadiene Styrene copolymer
PVC Polyvinyl Chloride (hard or soft)
2.2 Flat plate collectors
Flat plate collectors
In open air swimming pools flat plate collectors may be installed if also a solar
heating of domestic hot water for showers is required. Almost all glazed flat-plate
collectors currently available on the market consist of a metal absorber in a flat
rectangular housing. The collector is thermally insulated on its back and edges,
and is provided with a transparent cover on the upper surface. Two pipe
connections for the supply and return of the heat transfer medium are fitted,
usually to the side of the collector.

Because of the risk of corrosion of thermal collectors with copper absorbers,
these can only be operated in solar systems for swimming pool heating if a
separate solar loop is installed (i.e. indirect) including an external heat
exchanger.
2.3 Vacuum tube collectors
In special cases, e.g. if there is not enough area for the required absorber
surface or additional applications like cooling are desired vacuum tube collectors
may be chosen.
To reduce the thermal losses in a collector, glass cylinders with internal
absorbers are evacuated in a similar way to Thermos flasks. For evacuated tube
collectors the absorber is installed as either flat or upward-vaulted metal strips or
as a coating applied to an internal glass bulb in an evacuated glass tube. An
evacuated tube collector consists of a number of tubes that are connected
together and which are linked at the top by an insulated distributor or collector
box, in which the feed and return lines run. There are two main sorts of
evacuated tube collector: the direct flow-through type and the heat-pipe type.
Direct flow –through evacuated tube collectors In this design the heat transfer medium is either led via a tube-in-tube system
(coaxial tube) to the base of the glass bulb, where it flows back in the return flow
and thereby takes up the heat from the highly spectral-selective absorber, or
flows through a U-shaped tube.
Figure 7: Cross-section of direct flow-through evacuated tube collector (DGS,
2008)
Solar Energy Use in Outdoor Swimming Pools
EIE-06-085 SOLPOOL
11
Heat-pipe evacuated tube collectors In this type of collector a selectively coated absorber strip, which is metallically
bonded to a heat pipe, is plugged into the evacuated glass tube.
The heat pipe is filled with alcohol or water in a vacuum, which evaporates at
temperatures as low as 25°C. The vapour thus occurring rises upwards. At the
upper end of the heat pipe the heat released by condensation of the vapour is
transferred via a heat exchanger (condenser) to the heat transfer medium as it
flows by. The condensate flows back down into the heat pipe to take up the heat
again.
Figure 8: Cross-sectional view of a heat-pipe evacuated tube collector (DGS, 2008)
2.4 Hybrid Systems
In some cases a combination of different collector types may be the appropriate
solution for heating an open air swimming pool. In Germany some examples
exist were a glazed flat-plate collector is combined with an unglazed absorber
field. The flat-plate collector field is thus designed for heating domestic hot water
for the showers while the absorber field is directly linked to the swimming pool
water for heating.

Figure 9: Absorber and flat plate collector for solar heating (DGS, 2008)
Another hybrid solution may be a combination of air collectors and absorbers in
order to use different global radiation input for the different oriented collector
surfaces.

3. Objectives of the action
The energy world has changed fundamentally in the last few years, with high
escalating oil prices and with gas prices following behind. Worldwide energy
demand is increasing very rapidly, and given continued prospects for growth
particularly in China and India, it can be expected that this trend will not reverse
in the near future. It is clear that fossil resources will be depleted within the next
160 years, considering all known resources, which have not been made available.
This shows that using fossil resources is not favourable for any reason,
particularly with regard to the energy supply in the EU, which is estimated to
increase 70 % by 2030. Moreover the burning of fossil fuels results in substantial
emissions of green house gases (GHG).
Figure 11: Development of oil prices from 1960 until 2008 (source:
www.tecson.de)
In most heating applications fossil fuels are still dominating, this applies to the
heating of swimming pools as well. Solar energy, on the contrary, is a
sustainable energy source and does not produce any GHG-emissions. Therefore
Solar Energy Use in Outdoor Swimming Pools
EIE-06-085 SOLPOOL
14
the use of solar thermal systems for the heating of outdoor pools contributes to
solve the above stated problems.
Today there is no doubt that swimming pools represent an attractive unexploited
market for solar thermal systems.1 In particular for outdoor swimming pools
solar thermal applications are the best technical solution to generate the
demanded energy for the pool heating as well as for the generation of domestic
hot water (DHW) for showers.
Solar heating of outdoor swimming pools has three significant advantages
against other uses of solar thermal energy as shown in table 1:
Table 1: List of workshops for owners and operators
1 Low temperature differences
because the requirement temperature level is comparatively low
with 18 – 25 °C the use of inexpensive solar absorbers is possible
2 Solar radiation and seasonal operation
the period of the highest irradiation corresponds with the energy
demand periods. E.g. in Central Europe outdoor swimming pools
are operated between the beginning/middle of May until middle of
September. In this period 65 – 75 % of the annual irradiation
occurs
3 Simple system design
the pool water flows directly through the absorbers, therefore the
usual storage tanks are not needed as the pool fulfils this task.
These three positive conditions make outdoor swimming pools to
a very favourable application for solar thermal energy.
The main objective of the proposed project is to develop and implement
campaigns for the increased use of solar thermal systems for the heating
of outdoor swimming pools. One campaign concerns the owners and
operators of these pools, while the second concerns installers of heating and
solar systems. As a result of these experiences, a guideline is produced for the
implementation of similar campaigns in other European Member/Candidate
States. 1 White Paper for a Community Strategy and Action Plan COM(97)599 final (26/11/1997): Energy for the future: Renewable sources of energy

4. Facts and figures of the participant countries and regions
Solar thermal systems are predominantly used to generate hot water and to
augment the heating system in private households. The European market
leaders, i.e. Greece, Austria and Germany, have implemented public policies,
particularly in the starting phase of the market, which have been the key to their
success. In the 1980s, the Greek Government offered financial incentives,
combined with awareness raising activities. Several years after the main support
programmes, the market per capita is 16 times bigger than in Italy. Austria is
the leading continental Europe country in solar thermal. The success is based on
stable, long term public support schemes in several federal states, including
awareness raising, financial incentives, training of professionals, R&D funds and
demonstration projects. Germany is the largest market in Europe built up with
the help of sustainable policies. The financial incentive scheme “MAP” now enters
its 8th year. Awareness raising campaigns at federal and local level have been
implemented. In Germany, the internet platform "RegioSolar" supports
numerous and diverse initiatives such as proKlima-fund, solar festival in
Hannover and solar region in Freiburg.
Solar thermal systems are increasingly being used in both small private pools as
well as in larger community facilities and open air swimming pools. However, in
every country this particular application of solar thermal energy is far from
reaching its full potential.
Germany
According to the general manager of „Deutsche Gesellschaft für das Badewesen
e.V.“, there are around 6700 public swimming pools all over Germany. Out of
those 6700 there are 3200 outdoor swimming pools. The rest are indoor pools
and combined outdoor & indoor facilities (~1800), aqua parks (~300), and
school/learning pools (~1400). The company ZFS-Rationelle Energietechnik
GmbH made a study on public pools with implemented solar thermal systems. At
the end of the year 2007, a total of 799 public swimming pools in Germany were
equipped with a solar heating system, according to the named study. In most of
the cases they are outdoor pools and in rare cases a combination of outdoor and
indoor pool facilities. Fifteen of the listed swimming pools have exclusively indoor

facilities. Another important fact to point out is that 98.5% of the total outdoor
pools and outdoor in combination with indoor pool facilities, use absorbers as a
pool heating system. The remaining 1.5% use collectors.
Figure 12: Yearly installed solar systems and surface area of
absorbers/collectors in public swimming pools in Germany
Figure 1 shows the breakdown in number of systems installed and surface area
in relation to their year of installation. It can be seen that the years 1993 and
1994 were the peak years in terms of surface area of absorber/collector
installed, which were followed by almost a continuous decrease in the following
years. In the last two years the tendency is changing again to higher levels, but
even though those levels are still far behind those of the peak years. Since there
are approximately 3200 outdoor public swimming pools, more than 2400 pools
are potential clients of the solar thermal market.

The absorber surface area of implemented thermal systems is mainly medium
and large-size, as it can be expected from public pool facilities, according to the
division performed in SOLPOOL (small up to 100 m2; medium >100 m2 up to
500m2; large >500m2 up to 1000m2). Out of a total of 784 outdoor public solar
heated pool facilities, only 35 lie within the small-size absorber surface area
category. A total of 345 lie within an absorber area between 100 and 500 m2,
and the rest, i.e. 404, belong to the largest pool category.
There are two of the top solar thermal companies specialised in swimming pools
providing relevant data on the number and size of their installed systems. The
company Solar Ripp has installed already a total of 407 absorber solar pool
heating systems in Germany. As it can be seen in Fig. 2, most of the systems,
i.e. a 95,3%, have an absorber surface area smaller than 100 m2. Therefore, it
indicates that they have been mainly focused on small-size swimming pools
either from hotels or private owners. The „Deutsche Gesellschaft für das
Badewesen e.V.“ provides a figure of 625.000 swimming pools in private houses
and gardens, which fall in most of the cases within the small-size pool category.
Although at present there is no available information regarding the total number
of small pools in Germany equipped with solar thermal systems, the number of
the already existing small pools gives an idea of the market potential for this
sector.

In the case of the company Solar-Anlagen Lange GmbH, they have been involved
in the solar pool heating business since 1986. In their case, a total of 190 pool
heating systems have been implemented until the end of 2007. In their case, as
it can be seen in Fig. 3, they have focused both on medium and large solar
swimming pool heating systems.

Slovenia
In Slovenia there are only five implemented solar thermal systems for the
heating of swimming pools. Most of the implemented systems for heating the
swimming pool water are combined with sanitary water heating and space
heating. The Statistical Office of the Republic of Slovenia, which is the main
institution in charge for carrying out programs of statistical surveys, is not
recording data about the number of swimming pools neither their heating
systems. The only institution in Slovenia collecting some data about swimming
pools is the Slovenian Health Protection Institute, which monitors the quality of
the pool water. According to them, there are 174 swimming pool facilities
Solar Energy Use in Outdoor Swimming Pools
EIE-06-085 SOLPOOL
19
According to Slovenian Health Protection institute, there were 174 swimming
facilities with 581 swimming pools in Slovenia in 2007, from which 191 are
outdoor swimming pools.
Figure 17: Percentage of types of swimming pools, Slovenia, 2007 (Source:
IVZ, 2008)
The potential for the use of solar heating in swimming pools in Slovenia is quite
big due to high solar irradiation. The majority of swimming pools are suitable for
solar thermal applications. The potential varies with the source of existing
heating, heat demand and period of opening. Only swimming pools which are
using geothermal energy are excluded. The most
appropriate are swimming pools with longer period of
opening and higher heat demand, while potential in
swimming pools which are open only in short summer
period is limited and should be further estimated from
case to case. A smaller potential exists in the private
houses.
The solar radiation in
Slovenia is about 1.350
kWh/ m² per year while the
range in Germany is
between 700 and 1.100
Wh/m². k
In southern Europe, Italy,
Greece and Spain a
maximum of 1.800 kWh/m²
per year can be reached.
Thus, solar absorber

Greece
In the case of Greece, there has not been any official
administrative body for land property registration until
recently. This suggests that private swimming pools
(belonging to private buildings, houses, etc) cannot be
extracted by any official source, a fact that makes it
almost impossible to estimate or even consider their reach much

y interviewing three major companies that share 70% of the Greek market, a
total number and by no means imply the existence of a heating system. An
assumption towards the resolution of such an obstacle would be that it is rather
uncommon to use a heating system of pools in private buildings and houses, as
they are rarely used during the colder days of the year.
Another division of the private sector in Greece refers to hotels and other resorts.
A heating system for a swimming pool belonging to hotels and resorts is
practically desirable, as it may extend the swimming pool usage period to
approximately two months before and after summer. Therefore, assuming that
most of the big hotels and resorts have indeed installed a heating system for
their pools, it is still quite hard to consider and contact all of the owners, as well
as extract the required technical data. This may happen either because of their
unawareness of technical and economical characteristics or a general distrust
regarding economical data of their enterprise.
What seems significant for this project are the athletic o
swimming centres, which mainly belong to the publ
sector and are characterized by high density of attendance
(large number of visitors, independent of weathe
conditions). This makes it almost certain that a heatin
system is installed. A number of interviews were held wit
companies that manufacture and/or install swimming
pools and heating systems (both conventional and solar).
In Greece, approximately
1500 swimming pools
are installed every year,
out of which only 5 - 7%
are outdoor pools with an
installed heating system.
B
general image of the market was established and an estimation of the situation
was relatively easier accomplished. According to those interviews carried out
with manufacturers – installers of swimming pools and heating systems in
Greece, approximately 1500 swimming pools are installed every year, out of
which only 5 -7% are outdoor pools with an installed heating system. Each of
those companies installs 150 – 200 swimming pools per year and mostly for
private customers.

o the collected
An estimation based on online surveys and interviews with tourist organizations,
hotel chambers and swimming pool installers reveals that there are about
150.000 outdoor swimming pools installed. What has been suggested by many
companies is that, because of the climate of Greece, the heating systems for
outdoor swimming pools are not required during July and August. For that
reason, when solar heating systems are installed, the produced heat during that
period is employed exclusively for domestic water heating.
Czech Republic
In the Czech Republic approximately 10 % of the outdoor
swimming pools are equipped with a solar thermal system.
Some swimming pools are heated with fossil fuels, either
coal or natural gas. In the eighties some pools were
equipped with flat plate collectors and more recently heat
pumps and cogeneration units have been installed thanks
to the subsidy policy of the Czech government. According t
information from the Czech pool and sauna association there are 567 public
outdoor swimming pools in the Czech Republic. According to a survey carried out
for this project among those listed pools, 58 outdoor pools are heated using solar
energy and 65 are heated through the means of other sources.

According to statistics of MPO and survey of CZREA minimum 14 large outdoor
pools realised new solar system in last 3 years, it is nearly a quarter of number
of pools with solar systems estimated by CZREA. Total area of new systems is
2137 m2, total area of elder systems is 2206 m2.
There is no evidence of systems installed on small private pools; 70 000 m2 of
absorbers was delivered to retail stores in year 2007.
The area of installed systems in the Czech Republic increased during the
performance of the SOLPOOL campaign by nearly 100 % during last 3 years.
Lyon, France
In the region of Lyon, there are 57 municipalities (1 300 000 inhabitants) with a
total of 47 outdoor swimming pools or a combination of outdoor and indoor
swimming pools. France is one of the first European markets for swimming pools,
with more than 1 million of private swimming pools. At present, more than 3000
firms work in the swimming pool sector: around 200 manufacturers and more
than 2500 installers.

Province of Lecce, Italy
In the Province of Lecce there are no available statistical data about the number
of swimming pools and their heating systems. The only available data has been
produced by the tourist office of the Province of Lecce (Hotel, Camping, etc.).
According to their information there are about 100 swimming pools and six
hotels are equipped with a solar system for the heating of sanitary water.
In Lecce there are about 10 public outdoor swimming pools but at present none
of them have an implemented solar thermal heating system. The 10 indoor
identified pools use a conventional heating system.

5. Grant schemes
Although the operating costs of solar thermal systems for outdoor swimming
pools are clearly lower than those of conventional systems, the initial investment
costs of the former are relatively higher. Therefore, it is necessary to support the
implementation of such systems with regional or national grant schemes. The
participating regions and countries have identified the following schemes
accordingly:
Germany
In Germany a grant scheme from „Kreditanstalt für Wiederaufbau (kfw)“ in
Frankfurt, has been identified. The programme started on 2007 and it offers a
credit with reduced redemption to local authorities, owners and operators of
swimming pools to implement solar thermal systems. Local authorities can apply
directly to KFW, however the rest of the applicants must apply via their home
bank. The solar thermal system must have a collector area greater than 40 m2.
For outdoor swimming pools 80% of investment costs are financed by credit,
whereas 30% of the redemption amount is to be remitted.

Slovenia
There are currently two identified subsidies for solar thermal systems. The first
one comes from the “Slovenian Environmental Public Fund”. The scheme
supports the implementation of solar thermal systems in residential buildings for
owners up to a 25% of the investment but no more than 150€ per m2 for flat
plat collectors, 200€ per m2 for vacuum collectors, and 75€ per m2 for do it
yourself collectors. An additional amount of 10€ per m2 is granted for collectors
with quality standard “Solar Keymark”.
The second type of subsidy is a soft loan from the “Slovenian Environmental
Public Fund”. In this case, owners of residential buildings and their family
members, as well as municipalities, firms and entrepreneurs can apply for it. In
the last actual calls an annual interest rate of 3,9% for the credit for households
was offered. In the case of legal entities, the granted credit was the
EURIBOR+0.3%.

given by the “Greek Ministry for Economy and Finance”. It offers different types
of support such as: cash grant, covering part of the expense for the investment
project by the State; and/or leasing subsidy, covering parts for the payable
installments by the State relating to a lease which has been entered into for the
use of new mechanical and other equipment; or a wage subsidy for employment
created by the investment; or tax allowance. The investment incentives law is
applicable to enterprises having business activities in the primary, secondary and
tertiary sectors, i.e., all sectors of the economic activity. Among the eligible
categories for incentives under the Development law, the energy production from
renewable, and specially wind and solar, hydroelectric, geothermal energy and
biomass, is included.

A kollektorok által összegyűjtött hőenergiával nyáron a 700 m3 térfogatú úszómedence vizét fűtik, míg az év további részében a nap-energia hozzájárul a szomszédos óvoda használati melegvízének készítéséhez. A 2000. július 1. és december 31. közöt-ti monitorozási időszakban a kollektorok 4.3 MWh napenergiát hasznosítottak és ezzel 470 m3 földgázt takarítottak meg. A rendszer a Szent István Egyetemen okta-tási célokat is szolgál.

A Szent István Egyetem területén található gödöllői városi strand egyik medencéjének vizét
részben napenergiával melegítik. A beruházás 2000-ben készült el és a 7,3 millió forintos
beruházást a Földművelésügyi és Vidékfejlesztési Minisztérium, valamint Gödöllő Város
Önkormányzata együttesen finanszírozta. A napsugárzást hasznosító rendszer 18 db
üvegezett síkkollektort tartalmaz, melyek felülete összesen 33,3 m2. A kollektorok 45 fokos
szögben megdöntve állnak és deli irányba néznek. A kollektorok által összegyűjtött hőenergiával
nyáron a 700 m3 térfogatú úszómedence vizét fűtik, míg az év további részében a napenergia
hozzájárul a szomszédos óvoda használati melegvízének készítéséhez.
A 2000. július 1 és december 31. közötti monitorozási időszakban a kollektorok 4.3 MWh
napenergiát hasznosítottak és ezzel 470 m3 földgázt takarítottak meg.
A rendszer a Szent István Egyetemen oktatási célokat is szolgál.

The Impact Advisor
The Impact Advisor is a basic decision tool for policy makers or investment
decision makers to pursue the idea of solar pool heating. The simple excel based
Impact Advisor software tool provides the following technical capacities:
calculation of dimensioning, building and operation costs, economic gains, energy
savings and reduced CO2-emissions for solar pool systems against the existing or
conventional heating. The impact advisor is available in English, German,
Slovenian, French, Czech, Greek, Hungarian and Italian in the following link
http://www.solpool.info/2104.0.html.
Figure 28: SOLPOOL Impact Advisor
The Impact Advisor is accompanied by an instruction manual as well as by a
guide for feasibility checks.
Information panels
The consortium prepared 8 information posters (in English, Czech, French,
German, Hungarian, Greek, Italian and Slovene), which are currently being
displayed at more than 200 swimming pools in Europe. Two different posters
were produced according to the needs of the participating countries and regions.

8. Guidelines
Two important guidelines have been produced:
Guideline for SOLPOOL campaigns
This is intended as a guideline for the design and implementation of similar
promotion campaigns for solar swimming pool heating in other European
Member/Candidate States. The process starts with the identification of key
stakeholders and target groups, so that the level and scope of the dissemination
process can be established. Subsequently, the best dissemination tools and
strategies for the implementation of campaigns are defined.
Guideline for the continuation of SOLPOOL promotion
This is intended as a guideline for the consortium members in order to continue
with the SOLPOOL project promotion activities. The idea is to ensure the
sustainability of the project after the end, guaranteeing that the efforts of the
SOOLPOL partners in producing the material and building-up the network of
stakeholders are not in vain. Applying the strategies proposed and following the
suggestions given will ensure that the message of SOOLPOL, promoting the use
of solar swimming pool heating, continues to be brought to the target regions.

9. Impacts of the project and future activities
Overall objective of SOLPOOL project is the increase share of outdoor pools
equipped with solar thermal systems for heating the pool water. Rising
awareness by performing seminars and workshops using target orientated
information material and showing good practice examples all over Europe have
been the main issues the project team has worked on. Comparing the results in
the different partner regions it is evident that the SOLPOOL activities arouse
interest not only of the general public but also of owners/operators/installers as
the core target groups. By dozens of publications and consumer fair
participations a wide audience could be informed about the potential of solar
outdoor pool heating. Depending on the boundary conditions like market size,
funding programmes and weather conditions the solutions for solar heating of
swimming pool water varies as the case arises. Especially in the countries whit
very low ratio of solar heated outdoor pools a lot of installers could be informed
about the technology and were motivated to open this new business field for
their companies. In total 132 new pools were equipped with solar absorber
system in the project period and several individual consultations performed.
By elaborating a campaign manual and providing all deliverables on the project
home page the basis for multiplication of the SOLPOOL campaign in further
European regions and countries has been provided.
In specific, the project’s technical help desks will remain active to provide the
necessary support to potential installers or other stakeholders interested in
installing a solar thermal system for heating an outdoor swimming pool.
Moreover, the English and national pages of the project’s website will be
continuously updated, when important information is met on the respective
topics. In addition, the published informational material produced during the
whole project will keep on being promoted in the framework of the partners
activities (workshops, fairs, etc) that share subjects related to the SOLPOOL
project

10. Cooperation with other projects and programmes
During the project lifespan SOLPOOL project has collaborated with several other
IEE projects like SOLCAMP, SOLARGE, SOLAIR. All projects have a lot in common
- mainly they are focussing on bigger solar thermal systems. SOLPOOL project
partners are involved in several IEE programmes:
• Province of Lecce is working in SOLAIR. The objective of SOLAIR is to
promote and to strengthen the use and market implementation of solar
air-conditioning (SAC) systems. Focus is given – in addition to other
current projects in this field – to small and medium sized SAC systems in
the residential and commercial sector, combining domestic hot water
supply and space heating with air-conditioning. The Province of Lecce
works as a link between the SOLAIR and SOLPOOL project and ensure the
ongoing exchange.
• The SOLPOOL co-ordinator DGS also co-ordinates the EIE project
SOLCAMP – Solar Energy for Camping Sites. The overall objective of
SOLCAMP project is to increase the use of solar thermal systems on
camping sites in the participating regions and countries. Main activities
within SOLCAMP are the training of SolarCheckers, the development of a
simulation software and an intensive campaigning. Thus, a permanent
exchange between both projects is guaranteed. Especially, the network
developed in the frame of SOLCAMP will be used to distribute SOLPOOL
information as the project newsletter and advertisement of the final
international conference e.g. The SOLPOOL co-ordinator DGS cooperates
in the frame of its daily business with the German EIE SOLARGE project
partners Bundesverband Solarwirtschaft (BSW) e.V., Berliner
Energieagentur GmbH and target GmbH (Project co-ordination).
Additionally, DGS participated in dissemination events of SOLARGE as e.g.
in June 2007. The EIE project SOLARGE is a European co-operation project
to open up markets for large collective solar thermal systems for multi-
family buildings, hotels, public and social buildings.
• ApE is also partner in SOLCAMP project. In SOLCAMP ApE is collaborating
together with International tourism institute, one of the important national
institutions in the field of tourism. ApE is already using the established
SOLCAMP network of solar thermal systems and camping sites for current
and future SOLPOOL activities. Furthermore ApE is collaborating with
Slovenian solar thermal technology platform, which is the main institution
for solar thermal sector development in Slovenia.
• CRES is a partner in both SOLPOOL and SOLAIR projects. Bear in mind this
fact and after consideration of the potential synergies among the two
projects, as it was discussed during the SOLPOOL project meeting in
Solar Energy Use in Outdoor Swimming Pools
EIE-06-085 SOLPOOL
41
Athens, two events were finally organised and supported by both projects.
The reason of choosing this strategy was mainly guided by the nature of
the target groups, which for both projects are very similar. Moreover,
based on this fact such cooperation would have just positive effect for both
projects, as it would enhance the dissemination impact at the regions
where these events were held (Crete & Thessaloniki).

11. Conclusions and recommendations
The multiple dissemination activities carried out in the SOLPOOL project have
provided a lot of valuable information on how to carry out campaigns in the most
effective manner. As a result of the project experiences, it can be said that future
activities should always be planned in combination with parallel relevant events
of great interest were target audiences are involved; we recommend this when
talking about campaigns at a national level. The national level campaigns should
be mainly implemented in small countries or in countries where the market
potential is limited. However, for cases with great market potential we would
recommend a local/regional approach, using not only regional and local energy
related events to disseminate the SOLPOOL information but also local radio
stations and tv channels amongst others.
In some cases it has been difficult or even impossible to involve the umbrella
organizations of the target groups to act as partners or supporters. To solve this
problem efforts have been made to win members of the stakeholder community
as confederates. In case of SOLPOOL the planning engineers and producers of
solar absorbers could be won to support the activities. This has the advantage
that they have direct link to their clients and economical interests. During the
development of SOLPOOL project, it became apparent that the market and
potential for solar heating of outdoor pools vary from country to country or has
been comparatively rather small with regard to the specific boundary conditions.
Thus the application has to be enhanced from public outdoor pools to private
hotel pools and even indoor pools. Consequentially the target group has to be
changed and e.g. hotel owners have been included.
For future projects it is highly recommended to set performance indicators linked
to big investments not too ambitious. The process from arising the awareness
until the decision for investment takes normally quite some perseverance.
