“Dismantling”.

Operating principle of heat pumps

Heat pumps operate on the same principle as a refriger-

ator: same technology, only with reversed benefits. The

refrigerator extracts heat from foods, which is released

into the room through fins on the back.

The heat pump extracts heat from our environment:

air, earth or ground water. The extracted heat is condi-

tioned in the unit and supplied to the heating water. Even

when it is extremely cold outside, the heat pump draws

enough heat to heat a house.

Example: drawing of a brine/water heat pump with floor

heating:

4/4 = usable energy

approx. 3/4 = environmental energy

approx. 1 ⁄4 = external

electrical energy


Area of use and heat source requirements

Taking into consideration the ambient conditions, limits

of use and the relevant regulations, every heat pump can

be used in new or existing heating systems.

“Technical data / scope of delivery” overview,

WATER TEMPERATURE / WATER QUANTITY

The water in the extraction well of the heat source

system must have a minimum temperature of 7 °C all

year round and may not exceed a temperature of 25°C.

Depending on the heat output required or its cooling

capacity as a relevant variable for dimensioning the heat

source, a minimum water rate is required, which must

be provided by the heat source as a continuous output.

Before installing the water/water heat pump, a pump test

should/must be carried out for at least 12 hours with

verification of a quasi-constantly lowered water table

(persistence) in order to provide information about

the quantity of water available. For efficient operation

of the well, during the initial start-up the nominal flow

rate must be adjusted on the heat source side. Any

appropriate components, which enable balancing are

to be installed in the pipe network here. The material

of the components used must be chosen according to

the water quality. The necessary flow rate (heat source

water rate) must meet the heat pump's requirements.

“Technical data/scope of supply” overview.

WATER QUALITY

In Germany the well must be designed and built to DIN

4021 and VDI 4640 (in other countries according to the

corresponding regulations). Wells may only be drilled

and built by drilling companies with a permit in accord-

ance with DVGW W120. The water quality of the heat

source is defined as normal groundwater. Ensure that

the suction and return pipe always extends below the

water level by sufficient depth, to ensure that oxygen

is not added to the water (risk of iron oxide deposits).

Please discuss the problem of iron oxide deposits with

your well builder. During the planning the quality of the

groundwater should be checked in advance as well as

possible (e.g. by asking the competent water authority

or searching for data on existing adjacent wells) and sub-

sequently verified by water analysis in the built produc-

tion well. The following table helps to assess the water

quality.

IMPORTANT A water analysis and pump test must be carried

out before installing the water/water heat pump.

NOTE: Water analyses are prepared by water test labo-

ratories. Initial information about possible use of

groundwater is available from your local water

management authority. A pump test provides

information as to whether a sufficient quantity

/ rate of water is available to cover the require-

ments for the heating output of your unit. The

minimum groundwater flow rate must at least be

available as a continuous output.

“Technical data/scope of supply” overview,

“Heat source flow rate” section.

EVALUATION OF THE WATER ANALYSIS

Water constituents - minimum requirement. The water

should be analysed in advance for the test values listed

below (table). An important criterion to be used for

taking water samples is the DVGW Standard, Technical

Notices, Leaflet W 112 and use of the technical rules

listed in it (DIN, EN and ISO standards).

Designation Limit

pH value > 6.8

Iron level < 0.2 mg / l

Manganese level < 0.1 mg / l

Chloride level < 300 mg / l

Free chlorine level < 3 mg / l

Turbidity none

Technical freedom from sand

< 0,1 ml sand per10 l pumped water

IMPORTANT If a value does not conform to the value listed

in the table, a water/water heat pump may not

be used. Direct operation of the unit in conjunc-

tion with surface water, wastewater, industrial

wastewater or mixtures of water and alkali solu-

tions, acids or chlorine is also not allowed.


Heat meteringIn addition to proof of the system's efficiency, the

EEWaermeG (German law on renewable energy heat)

also requires heat metering (referred to in the follow-

ing as WME). The WME is mandatory for air/water heat

pumps. For brine/ water and water/water heat pumps, a

WME must be installed for flow temperatures ≥ 35 °C.

The WME must record the total thermal energy output

(heating and domestic hot water) in the building. In the

case of heat pumps with heat metering the analysis is

carried out via the controller. This displays the thermal

energy output into the heating system in kWh.

NOTE. Unit variants with or without heat metering are

available.

Operation

ENERGY SAVING USE OF THE HEAT PUMP HEATING

By deciding to purchase a heat pump or a heat pump sys-

tem you are making a long-term contribution to protect-

ing the environment through low emissions and reduced

primary energy use.

You can operate and control the heat pump system with

the control panel of the heating and heat pump control-

ler.

NOTE. Make sure that the control settings are correct.

Operating manual of the heating and heat pump

controller.

To ensure that your heat pump or heat pump system

operates efficiently and in an environmentally friendly

way in heating mode, please pay particular attention to

the following:

€ ENERGY SAVING TIP Avoid unnecessarily high flow temperatures.

The lower the flow temperature on the heating

water side the more efficient the system.

€ ENERGY SAVING TIP Preferably use purge ventilation. Compared to

continuously open windows, this form of ventila-

tion (fully opening windows for a short period,

two to three times a day) reduces energy con-

sumption and your heating bill.

Care of the unitYou can clean the outer surfaces of the unit with a damp

cloth and proprietary household cleaning products.

Do not use cleaning or care products that contain abra-

sives, acids and/or chlorine. Such products would irrepa-

rably damage the surfaces and could also cause technical

damage to the unit.

Maintenance of the unitThe cooling circuit of the heat pump requires no regu-

lar maintenance.

According to EU regulation (EC) 517/2014, leak

inspections and maintenance of a log book are required

by law for certain heat pumps!

Log book for heat pumps, Section “Information

on use of the log book”.

The components of the heating circuit and the heat

source (valves, expansion vessels, circulation pumps, fil-

ters, dirt traps) should be tested and cleaned as needed,

however, at least annually, by qualified personnel (heat-

ing or refrigerating system fitters).

It is best to arrange a maintenance agreement with a

heating installation company. The company will arrange

the necessary regular maintenance work.

CLEANING AND FLUSHING UNIT COMPONENTS

CAUTION! Unit components may be cleaned and

flushed only by customer service person-

nel authorised by the manufacturer. Use

only liquids recommended by the manu-

facturer.

After flushing the condenser with chemi-

cal cleaning agent, any residues must be

neutralised and the system intensively

flushed with water. Always note and follow

the technical data of the respective heat

exchanger manufacturer.


MalfunctionsIn the event of a malfunction, you can detect the cause

of the malfunction via the diagnostics program of the

heating and heat pump controller.

Use of modern, energy-efficient heat pump systems

is becoming increasingly widespread. Their ingenious

technology enables these systems to achieve very good

efficiencies. The decreasing space available for heat gen-

erators has led to the development of compact units

with increasingly smaller cross-sections and high capaci-

ties. This means the complexity of the systems and the

material diversity are also increasing, which plays an

important role especially in their corrosion behaviour.

The heating water not only affects the efficiency of the

system, but also the life of the heat generator and the

heating components of a system.

The guide values of VDI 2035 Part I and Part II must

therefore be complied with as minimum requirements

for proper operation of the systems. Our practical expe-

rience has shown that the safest, most reliable and fault-

free running is achieved with so-called low-salt operation.

VDI 2035 Part I provides important information and

recommendations regarding scaling and its prevention in

heating and domestic hot water heating systems.

VDI 2035 Part II primarily deals with the requirements

for reducing heating water corrosion in hot water heat-

ing systems.

PRINCIPLES OF PART I AND PART II

The occurrence of scaling and corrosion damage in hot

water heating systems is low, if

- proper planning, design and commissioning is carried

out

- the system is closed in corrosion terms

- adequately dimensioned pressurising is integrated

- the guide values for the heating water are complied

with

- and regular servicing and maintenance are carried out.

A system log should be kept, in which the relevant plan-

ning & design data is entered (VDI 2035).

DAMAGE THAT CAN OCCUR IN CASE OF FAILURE TO

COMPLY WITH THE ABOVE

- Malfunctions and the failure of components (e.g.

pumps, valves)

- Internal and external leaks (e.g. from heat exchangers)

- Cross-section reduction and blockaging of compo-

nents (e.g. heat exchanger, pipes, pumps)

- Material fatigue

- Gas bubbles and gas cushion formation (cavitation)

- Negative effect on heat transfer (formation of coat-

ings, deposits) and associated noises (e.g. boiling

noises, flow noises)

LIMESCALE – THE ENERGY KILLER

Filling with untreated drinking water inevitably leads to

the precipitation of all calcium as scale. The consequence:

limescale deposits form on the heat transfer surfaces of

the heating. The efficiency falls and the energy costs rise.

A rule of thumb is that 1 millimetre of limescale deposit

causes an efficiency loss of 10%. In extreme cases it can

even cause damage to the heat exchangers.

WATER SOFTENING TO VDI 2035 – PART I

If the water is softened in accordance with the VDI 2035

guidelines before it is used to fill the heating system, no

scale can form. This effectively and permanently prevents

limescale deposits and the resulting negative effects on

the entire heating system.


CORROSION – AN UNDERESTIMATED PROBLEM

VDI 2035, Part II, deals with the problem of corrosion.

Softening the heating water can prove to be insufficient.

The pH value can significantly exceed the limit of 10. pH

values higher than 11 can set in, which even damage rub-

ber seals. The VDI 2035, Part 1 guidelines are fulfilled;

however, VDI 2035, Part 2 suggests a pH value between

8.2 and maximum 10.

If aluminium materials are used, which is the case in

many modern heating systems, a pH value of 8.5 must

not be exceeded! Because otherwise there is a threat of

corrosion – aluminium is attacked without the presence

of oxygen. Therefore, apart from softening the heating

fill and make-up water, the heating water should also be

appropriately conditioned. This is the only way to com-

ply with the VDI 2035 requirements and the recommen-

dations and installation instructions of the heat pump

manufacturer.

Part 2 of VDI 2035 also refers to the reduction in total

salt content (conductivity). The risk of corrosion is far

lower if deionised water is used than is the case if the

system is operated with salty, i.e. softened water.

Even if the water has been softened beforehand, it con-

tains dissolved, corrosive salts, which act as electrolytes

due to the use of different materials in the heating sys-

tem and therefore accelerate corrosion processes. This

can ultimately result in pitting.

ON THE SAFE SIDE WITH LOW-SALT OPERATION

The problems listed above do not occur at all with low-

salt operation, as the heating water contains neither

corrosive

salts such as sulphates, chlorides and nitrates nor alkalis-

ing sodium hydrogen carbonate. The corrosive proper-

ties of deionised water are very low and in addition, scale

cannot form in the boiler. This is the ideal approach for

closed heating circuits, in particular, because low oxygen

input into the heating circuit can also be tolerated.

In general, when the system is filled with deionised

water, the pH value sets itself within the ideal range due

to “self-alkalinisation”. If necessary, a pH value of 8.2

can be very easily alkalised by adding chemicals. In this

way, optimum protection of the entire heating system is

achieved.

MONITORING

Analytical recording and monitoring of the relevant

water values and the added active conditioning sub-

stances is of decisive importance. Therefore, they

should be monitored regularly using appropriate water

test equipment.

FLUSH AND FILL THE HEATING CIRCUIT AND

THE DOMESTIC HOT WATER TANK

Place a bleeder (vent) at the highest point of the

heating circuit in the heating water outlet (flow)…

If necessary, place a bleeder at the highest point

of the heating circuit in the heating water inlet

(return)…

Open unit, if closed…

“Transport to the installation location”, and

.

Flush and fill the unit via the filling and draining tap...

IMPORTANT Do not exceed a pressure of 2.5 bar when flush-

ing the unit. The drain line of the heating circuit

safety valve must be closed before flushing and

filling.

BLEEDING THE UNIT

The unit is bled automatically if the bleeder (vent valve)

of the safety assembly is open. If the heating circuit is

filled or drained, the venting valve of the safety assembly

opens.

BLEEDING THE CIRCULATION PUMP OF THE HEATING

CIRCUIT

Unscrew the screw cover in the middle of the circulation

pump until loose and close again after venting.

BLEEDING THE DOMESTIC HOT WATER TANK

To bleed the domestic hot water tank, the domestic hot

water charge circuit must be flushed separately.

To do this, manually switch the domestic hot water

changeover valve to domestic hot water charging. After

bleeding, return it to the initial position.


NOTE: Once the heat pump, heating circuit and domes-

tic hot water charging circuit have been flushed,

the bleeding program of the heating and heat

pump controller must be started, after the con-

trol panel has been installed.

If no further steps follow, install the front panel.

Insulating the hydraulic connections

NOTE. Insulate the heating circuit and the heat source

according to relevant local standards and guide-

lines.

Check all hydraulic connections for leaks. Perform

leak test…

Insulate all connections, vibration isolators, con-

nections and pipes of the heating circuit and the

heat source. Insulate the heat source so that it is

vapour-diffusion tight.

Installing the control panelThere are 4 each recesses at different heights in the

front panel of the unit for fastening the control panel:

1 four upper recesses

2 four lower recesses

There are 4 hooks at the rear of the control panel,

which are used to hook the control panel on the front

panel of the unit:

Hook the control panel's hooks into the recesses

of the front panel (either in the upper or lower

recesses)...

Example:

Control panel in upper recesses


Push down the hooked in control panel, until it

latches into place…

Push the control cable of the heating and heat

pump controller into the right-hand socket on the

underside of the control panel…

NOTE. A connection to a computer or a network can

be made via the left socket at the bottom of the

control panel, thereby allowing the heating and

heat pump controller to be controlled remotely

from there. This requires a shielded network

cable (category 6) to be laid through the unit

during the electrical connection work.

Operating manual for the heating and heat pump

controller, “Qualified technician” version, “Web

server” section.

If this network cable is available, insert the

network cable's RJ-45 connector into the left

socket of the control panel.

NOTE. The network cable can be exchanged at any

time. In order to be able to connect it, the

screen must first be removed.
