Sani Grand City is a recently erected building, located near

the thermal district of Ilidža in Sarajevo (Bosnia).

At the ground floor there is a shopping center, on which the

residential part is located. The flats are placed on 5 levels

with a central court. The thermal plant described serves the

residential part of the building.

The first offer, during the budgeting in close collaboration

with the client, was to install a pure centralized system, with

DHW production with tanks and heat boxes only for heating

accounting, to contain the thermal power need.

Since the municipality had allowed to exploit the near hot

spring for integration of the energetic need, by means of

plate exchangers, and the choice of aluminium radiators as

heating terminals, the client has chosen an easier system

solution with the generation of a single high temperature

heating fluid (70°C) to satisfy both the heating and DHW

production requirements (the domestic hot water is

produced with the plate exchangers integrated in the heat

boxes). As a consequence it has been necessary to calculate

an adequate contemporaneity coefficient for the DHW,

in order to avoid the oversizing of the generator and the

distribution network diameters. Due to the number of flats

(176) the coefficient was at first estimated about 30%, but

it has been reduced for the hot spring integration and the

client has chosen for the plant a lower coefficient of 11%.

The result was a power supply of 1350 kW (instead of the

900 kW for the heat boxes for heating account only). The

total thermal load of the building has led to the choice of a

heat generator made of 9 condensing boilers with a heating

output of 150 kW each.

Due to the high numbers of installed boilers and the

consequent length of the primary circuit flow/return

manifolds, it has been realized a hydraulic circuit with

inverted return, to avoid not balanced flows and boilers

working with a flow lower that the minimum to dispose the

burner power.

As mentioned, the heat boxes had to be provided with plate

exchangers to DHW production. Moreover, due to the plant

size and the distribution network growth, it has been chosen

a heat box with integrated pump, to help the system balance

and to contain the expenses for the booster pumps of the 5

risers. The choice has been to install Baxi Luna SAT RSP.

Concerning the collection and transmission of consumption

data, the client has decided to realize a wireless network,

since already adopted in a similar system, realized the

Page 6: SYSTEMINFO #0

previous year in the sky resort of Bjelasnica, with very good

results. To grant the transmission, 11 aerials each floor and a

further aerial near the porter’s office with a serial connection,

which does the consumption data download.

In the end, even if the heat boxes were not a new issue for

the client, the realization of such a system assumes very

close evaluation.

2 years later the first ignition (during this period, the heat

boxes have always been monitored by the client), the

solution is reliable and economically in line with the fixed

energy saving goals.

Parque Ñuñoa in a recently erected building, located in the

elegant residential area of Macul in Santiago (Chile).

It is a valuable building for a medium-high target (the

structure has a 4000 m2 with a swimming pool). The

contractor company, following the growing trend of pollution

reduction and energy saving, has chosen (first between all

competitors) a system solution with condensing boilers in

cascade.

This choice has led the 95% of the flats to be sold within

100 days, despite the market tendency to prefer horizontal

houses after the earthquake of February 2010.

The system solution is a centralized heating system, with

DHW production with tanks located at the ground floor, for

safety reasons in case of earthquakes, since the thermal

plant is on the top of the building (27° floor).

As for the hydraulic scheme, from the thermal plant, besides

the DHW circuit, come 2 raisers of the heating circuit, which

are sectioned in correspondence of the 9° floor with a plate

exchanger feeding the underlying heating circuit, due to the

height of the building (and the high static pressure there

would be in the heating terminals of the lower floors). The

value of the static pressure in the 2 parts of each raiser is

not higher than 5 bars.

An average thermal need of 5,5 kW is expected for each

flat, so the total need was about 1350 kW. The thermal

load calculated has led to the choice of 9 floor standing

condensing boilers in cascade with 150 kW heating power.

The client has adopted such a power share to maximize the

average seasonal performance. Given the mild weather, to

reach this goal, it is very important the minimum value of

the boilers modulation range. Furthermore, with this kind of

system solution, the risk of lack of performance, in case of

arrest of one or more boilers.

The primary manifold and the hydraulic circuit breaker

have been sized and realized “ad hoc” in the construction

yard. Due to the high numbers of installed boilers and

the consequent length of the primary circuit flow/return

manifolds, also in this case, it has been realized a hydraulic

circuit with inverted return, to avoid not balanced flows

and boilers working with a flow lower that the minimum to

dispose the burner power.

Page 10: SYSTEMINFO #0

10

The distribution in the flats is done by means of zones valves

controlled by the room thermostat of the flat itself. The

energy consumption is represented for each user with 2

volumetric meters (heating and DHW consumption).

In the end, for the Chilean market, this is one of the most

innovative system realized so far. It is and will be the object

of a close analysis of the client regarding the annual energy

saving. Furthermore the thermal plant here presented has

began the reference point in similar systems planning in the

metropolitan area of Santiago.

It is a accommodation facilities complex consisting of a

Residence and a Hotel with 33 and 27 rooms, for a total of

129 beds.

The 2 buildings are 50 m distance and are served with

the same system for the DHW production. The complex is

opened only during the summer season, so it requires only

DHW production from the centralized system.

Old system

The existing plant was made of a single boiler installed in

a dedicated room. This heat generator provided the DHW

production with a plate exchanger.

The decision of enlarging the accommodations and the

consequent increase of DHW need, required the installation

of a solar system to integrate the existing plant, with pre-

warming function. Very important in this evaluation was

the necessity of containing the heat generator power and

the gas consumption. To grant users’ comfort 2 recycling

systems, one for each building, with independent supplying

have been employed. In this way, the plant is able to supply

DHW in a brief time in any moment of the day.

New system

As said, the increased DHW requirement has led to the

installation of a solar system, to integrate the existing 240

kW boiler. To ensure the installation of an adequate number

of collectors, avoiding for lack of space of mounting them

of the roof, a dedicated structure have been planned on

the ground. The collectors have been installed on the flat

cover of the parking area in between the 2 buildings. The

collectors have been mounted horizontally with in rows of

2 with a multiple connection. The installation is 30° slope

with an orientation close to south, values that optimize

the summer functioning of the solar plant. The horizontal

mounting has reduced the shadows between the collectors

and the installation of a bigger number. The structure,

besides being an anchor for the panels, is a further benefit

for the customers that can use covered parking place. Due

to the dimensions of the solar system, it has been cut in 2

parts, to optimize the hydraulic and electrical functioning.

The 2 parts have a multiple connection, and, to maximize

the efficiency and to help a bigger thermal exchange during

spring ad autumn, in the plant with 14 collectors and 2 tanks,

the 2 internal exchangers have a serial connection to reach a

Page 14: SYSTEMINFO #0

14

thermal exchange power of about 105 kW. The management

of the solar system flows have been grant by means of 2

circulation groups with multiple connection, in order to win

the head losses (localizzate e distribuite) of the solar plant.

A precise sizing of the main pipes of 35/32 mm and 28/25

mm and the secondary (interrate) pipes of 22/20 mm, has

allowed to contain the head losses and to gain an adequate

speed for the correct system working. To have a correct

heating fluid flow for the functioning, every solar circulating

group have been set to the highest speed in the working

range.

The solar controller allows the electric management of the

circuit, controlling the functioning and with electrical losses

reduction, since it makes the fluid circulating only if the

collectors are able to exchange a minimum value of solar

energy.

On the controller have been activated also the protection

and cooling functions to protect from temperature peaks,

which are very brief due to the DHW requirement. To

have an uniform distribution of the head losses related

to the project flow of 30 l hour/m2 collector, due to the

distance between the collectors and the tanks. If the solar

system does not satisfy the primary energy requirement for

DHW production, a diverter valve directs the pre-warmed

water through the plate exchanger feed by the boiler. The

boiler integrates the heat need to get DHW at the desired

temperature at any moment. Every recirculating system is

supplied with another diverter valve, that directs the water

of the recycle circuit through the exchanger or the tanks,

depending on the temperature of the return and of the solar

tank storage.

Page 15: SYSTEMINFO #0

15

The thermal power of the solar system is about 60 kW. During 5 months opening, expected data are:

• Energy from the solar plan for DHW production: 40 MWh

• Energy from the boiler for integration: 18 MWh

• Gas saving: 4500 m3

• CO2 emissions avoided: 12.000 kg

• System efficiency: 50%

Real data, coming from bills of the relevant period, are:

• Opening days: 150/year (5 months)

• Saving in the bill with reference to the old system: 3500 €/year (5 months)

Thanks to the centralized solar plant installation, the structure has had a saving for seasonal energy expenses of about 30% with

reference to the previous year.

Old system of the City Hall and City Theatre New system of the City Hall

In 2005, when the 110-year-old Biddeford City Hall, and the

City Theatre as well the the Ice Arena’s, each needed new

heating systems, following the recommendation of a board’s

member, City Council approved the installation of Baxi Luna

HT 1.65 commercial boilers in the facilities. The investment in

the greener and more efficient Baxi heating solution paid off

immediately, with annual fuel bill reductions of 50% fuel at City

Hall and City Theater, and 30% less at the arena. The City also

saved $20,000 a year previously needed to maintain the old

system, and found that employee absenteeism had dropped

dramatically with the high efficiency and environmentally sound

heating system. In fact, the monthly oil bills used to be much as

$5,000 for City Hall and City Theatre, while the natural gas bill

has not exceeded $1,200 over the past years.

Ormond College - Studentaccommodation

Page 21: SYSTEMINFO #0

Ormond College occupies 10 acres of land adjoining the

University of Melbourne. The land was allocated to the

Presbyterian Church by the University in 1853 for the

establishment of a residential college ‘of and within the

University of Melbourne’, and under the auspices of the

Church. However, it was not until 1877 that the Church, with

Alexander Morrison Headmaster of Scotch College, convened

a committee to plan for the establishment of the College. The

architect was the renowned Joseph Reed, designer of many of

Melbourne’s important public buildings, and the brief was to

create a striking and elegant College that would be a lasting

and significant landmark in Melbourne. Indeed the building

is of a magnificent neo-gothic architecture and the paddocks

have changed in to extensive gardens to provide a unique

backdrop for formal and informal functions.

The College houses 330 single student style bedrooms. These

facilities are used by interstate and foreign students during

the year. In summer time when everyone goes home, visitors

are most welcome to stay whilst visiting Melbourne.

The existing heating of the college dates from the 1950’s

where a central single internal boiler was installed with

radiators throughout. Not only in bedrooms, but also offices,

hallways and the Grand dining room were fitted with hydronic

heating panels.

Over the years the boiler has been upgraded from oil to gas.

In 2010 the single Natural Gas atmospheric 600kW boiler was

replaced by 4 x 150kW BAXI Power HT condensing boilers in

cascade.

The College embraced the idea of the cascade installation

knowing that a cold night at any time of the year is of the past.

The heating plant now will always have a minimum of 75%

capacity when one of the boilers requires maintenance.

The contractor installed the cascade installation as per BAXI’s

recommendations, each boiler has a primary pump which

circulate the system water through the hydraulic manifold

and separator. The cascade is controlled via the temperature

regulator for cascade systems (RVA47) with an outdoor sensor

set at 21° C with a night set back. The system starts operating

on the 1th of May and switches off on the 1st of November

(Southern Hemisphere). All radiators have a thermostatic head

except for the common hallways. It is a very simple but reliable

system.

Page 22: SYSTEMINFO #0

22

For the flue we used 100mm Stainless Steel for each boiler.

The contractor was able to use

the same roof penetration from the old boiler. (The diameter

of the hole was 760mm)

From the data of the energy used of the last two winters the

cascade system resulted in a drop in the gas consumption.

The building has 3 levels, each of them is 220 m2, of which

actually 2 floors are used. Length of the building is 21 metre

and faces to south-west direction. Other side of the building

is built next to the warehouse. It’s made of burnt bricks

(Wienerberger Porotherm 30 cm + heat insulation 15 cm).

The calculated heat loss is 30kW. The used temperature

step is 40/30˚C. The first floor level houses the commercial

department (sales, purchasers, storekeepers). On the second

floor level are placed the accounting, executive offices.

The system serves two different purposes: heating and cooling.

It is planned to use different kind of heat energy including

fossil and renewable. On first floor a wood heating boiler

is placed, which is heated with dropouts wood packaging

(disposable pallets). A gas boiler, DHW storage tank and

two puffer storage tanks are located on the second floor.

On the flat roof, there are 3 rows of 6 solar panels in serial

connection, facing directly south (installed with 45° slope).

80% of DHW requirement is produced by the solar plant. The

working hours of the Comfort controller for DHW storage tank

is 2578 hours (max temperature 72°C), for the puffer tanks is

2250 hours. (collector max temperature is 110,4°C.)

The heating system consists of 3 heating zones (one for

each floor), and many heating/cooling zones nearly equal

to the number of rooms. Each one of the 3 heating zones

are controlled by temperature regulator for mixing systems

(RVA46 controller), while the ceiling heating/cooling zones are

controlled with regulators, which can be turned to heating/

cooling mode. The cooling system can reach 15°C-18°C cold

water, in summer.

The wood boiler directly charges the UBPU 1500 puffer

storage tank.

Solar system strategy:

Speaking about solar system controller, DHW storage tank has

the priority on solar system: if its temperature is higher then

the set value the controller turns the diverter valve to charge

the second UBPT storage tank (1500 l puffer storage).

Gas boiler strategy:

There is a boiler interface for climatic regulators (OCI 420)

in the gas boiler’s control panel, to receive exact heating

value needs. The gas boiler starts working if the storage tank

heating value is not enough to fulfil the heating requirements

Page 28: SYSTEMINFO #0

which is calculated by a controller linked to temperature

regulator for mixing systems (RVA 46) by DATA bus

has been built in 1983, with a capacity of 1375 seats, this

structure has recently done an important renovation of the

technological systems. The intervention has involved the

change of the thermal plant where condensing boilers have

been installed.

The project provided for a power of 450 kW, with 10%

modulation of the total power, since the users (gym, locker

room and cafeteria) rarely require a contemporaneous

usage of the services.

The thermal plant is located in the -1 floor, so the boilers

had to be reliable and with reasonable dimensions. For

these reasons, the boilers which have been chosen are 3

Power HT 1.1500 (dimensions hxwxd 80x45x113 cm).

Boilers

Further the dimensions, the reasons were also energy

saving and to reduce of pollutant emissions. The

characteristics of Power HT can be summarized as

following:

- The stainless steel burner, through the internal spreader

and the special micro-perforation of the cylindrical

surface, grants a uniform spread of the air-gas mixture

independently from his length.

- The primary exchanger, totally made of stainless steel,

is built with two cylindrical flue chambers, vertically

positioned (burner chamber and condensation chamber).

Inside the cylindrical surface there are stainless steel coils,

in which run the water of the primary circuit. In the upper

chamber the warm flues discharge gives heat to the return

water of the system, contained in the coils, provoking the

condensation of the flues themselves and giving latent heat

to the water, pre-heating it before it enters the chamber of

the burner.

- The pre-mixing unit that grant constantly to the burner

an optimal air-gas ratio independently from the number of

turns of the fan limiting to the minimum the consumptions

and ensuring always the correct combustion (that means

reduction of the pollutant emissions).

Heating system

The heating system serves 3 locals: gym (annex to the ice

rink), the cafeteria and the locker room. These uses are

heated with radiators served with 3 high temperature

circuits., while air-treatment machines, with exchange

batteries supplied with 5 mixing circuits, are used for

conditioning during winter.

Given the number of circuits and the type of system, special

attention have been paid to the sizing of the hydraulic

separator, moreover on the primary circuit a second

circulator for each boiler have been installed to decrease

Page 32: SYSTEMINFO #0

32

the difference of flow between primary circuit and second

circuit. This solution, jointly with a boiler flow temperature

depending on the outdoor temperature, allow to maximize

the efficiency and the energy saving. Special attention have

been paid also to the insulation of the pipes, due to the

length of the distribution network.

The complex “Le Residenze” is a new building designed with

high quality standards, located in the historic center of Busto

Arsizio.

The building is rated “A” in Energy Performance Certificate,

due to the innovative design, which special attention to the

thermal insulation and advanced technology systems.

Four centralized heating systems have been designed, in

order to make independent the 4 stairwells of the building.

Four Baxi modular condensing generators (GMC) have been

installed combined with a solar system for the centralized

DHW production and ari/water heat pump. This system

permits to optimize the annual generation performances,

using the heat pump both for cooling and heating, in this

case, it works only this outdoor temperatures higher than

6°C, with working conditions which allow a high COP. The

boilers in cascade work when the outside temperature is

below 6°C, when the efficiency of the heat pump decreases

also due to the frequent defrosting cycles.

The choice of which heat generator was to work is

automatically done by means of electric diverter valves, while

the integration to the solar system to DHW production is

always effected by the condensing boilers.

The GMC outdoor installations allow to exploit the whole

surface of the building.

Inside the accommodations, Luna SAT RH (hydraulic

connections G3/4’’) or RHG1 (hydraulic connections G1’’)

have been mounted, according to the heating/cooling

requirements of the flat.

The consumption are recorded by a M-BUS transmission

network to which are connected the heat recorder and the

cold/hot water flow meters.

The flats are supplied with underfloor heating systems, while

fan coils are installed in false ceiling for summer cooling.

Diverter valves change from summer to winter mode. In

commercial premises, wall mounted fan coils serves both for

heating and cooling.
