REDUCE THE COSTS OF TAP WATER
HEATING BY 4-TIMES
Advantages of water heating with a heat pump
In addition to central heating, the heating of domestic hot water is the second largest expense in a household budget. After 21 years of market
presence, it has now become completely self-evident that domestic hot water heating by means of a heat pump is by far the most economical
solution. The comparison of costs for tap water heating (for an average family) with different energy products clearly confirms the above
statement in every respect.
Solar panels (SP) may be compared to the cheapest way of heating tap water, but only if installed in an ideal position. However, this only holds
true until we compare both investments. The investment in solar panels is normally twice as big as the investment in a tap water heat pump.

Costs of tap water heating for an average
family with different heating systems (EUR/year)
Why should we use a heat pump for tap water heating?
1. Cost savings in heating are increased by at least four times.
2. The most eco-friendly way of heating tap water – CO2 emissions are reduced by over 62%.
3. Really short reimbursement period of the investment (6 to 7 years) – if we exclude the costs of the water heater, which we need in any
case, then the reimbursement period is even shorter.
4. In addition to tap water heating, we also get the possibility of cooling smaller spaces, cellars or storage rooms, free of charge.
5. The possibility to use the heat pump throughout the entire year and to connect it to any heating boiler, since all heat pumps have an
additional built-in tube heat exchanger. The combination with a wood or biomass stove is particularly popular, because in the summer heat it
is very inconvenient to burn wood. It is much more convenient to simply use a heat pump to warm up water.
6. In comparison to the solar panels, the investment in a heat pump is half as big, warm water is provided throughout the whole year, irrespective
of the season, and there are no particular difficulties with the installation and maintenance.
7. The purchase of a heat pump is often subsidized by the state, which means that the investment is even more favourable and is refunded
even sooner.

SUPERIOR QUALITY AND BUILT-IN
TOP EQUIPMENT
Continuous development, over two decades of market presence and consideration
of the consumers‘ wishes made us realize that what was good only a few years ago,
today is not sufficient anymore. Now even the most basic Types have numerous
advantages and great built-in equipment.
Built-in equipment:
DE – TUBE large-surface condenser
External large-surface condenser is wound around the
outer side of the tank and enables a faster and more
even water heating. It prevents the accumulation of
lime scale, because a much larger surface is heated and
therefore smaller temperature differences are necessary.
Indirect heating also prevents leakage of the refrigerant
into the tap water. During the production, the pipe
system is filled with nitrogen, which prevents impurities
and moisture to break into the cooling system and this
is in fact the basis for a long lifespan of a heat pump
4
ENAMEL - C - 850
Do you still remember the enamelled pots, which
were practically indestructible and could only
be damaged mechanically (e.g. fall on the floor)?
For hot water tanks this is the most high quality
and durable protection. In Europe, almost 90% of
all hot water tanks sold in 2011 were coated with
enamel. Enamel is en entirely natural material.
When the enamel coated surfaces are fired (at
850°C), the enamel fuses with the basic sheet
metal into a smooth and uniform coating.
VARIO - TEX
MG - PROTECT
Thermostatic expansion valve. The heat pump has
to operate in extreme and changeable conditions,
since the water temperature ranges from 10 to
60°C. The temperature of the ambient air varies as
well. TXV enables a fast adaptation to such conditions and represents at the same time the basis for
an increased efficiency.
A built- in Mg anode, dimensioned according to
EN standards, provides a complete anti-corrosion
protection of the hot water tank. The entire inside
surface of the water heater and the heat exchanger are protected with high quality enamel. However, if by any chance a small part of the enamel
coating is damaged, the magnesium immediately
protects the damaged surface.
HEAT EXCHANGER
PU 50 - CLOSE
An extra built-in tube heat exchanger, integrated
in all water heaters (except 100 l), enables the
use of a secondary heating source, e.g. boiler
(wood, oil, gas, biomass) or the connection of
solar panels. Solar heat pumps even have two
integrated heat exchangers.
A high-quality, closed-cell PU insulation keeps
the water in the tank warm, even when the water
is not used. The PU insulation and the protective
sheet-metal cover of the tank form a compact
body with minimal heat losses.
XL - OPTI evaporator
RC – ROTARY compressor
Evaporator with enlarged fin spacing,
enlarged surface and optimal refrigerant
distribution enables an effective operation
even at low temperatures.
Highly efficient rotary compressor was developed
especially for tap water heat pumps. Compared
to piston compressors, the energy efficiency of
rotary compressors is over 30% higher. What
is more, the very construction of the rotor
guarantees still operation and a faultless start-up
even after several months of stand-by mode.
If there is no space on the floor, there is definitely space on the wall!
HEAT PUMPS IN THE BATHROOM
The latest versions of heat pumps with air duct are designed precisely for wall
installation. The applicability of heat pumps thus extended to virtually all possible
fields of use. They are also the only substitution for small capacity electric water
heaters. Such versions are suitable in the following cases:
For installation inside houses: in a bathroom, storage room or any other room, from which heat can be
recovered directly or it can be recovered from an adjoining room. The cooled air can be discharged into
the surroundings during winter or channelled back into the room during summer.
For all families of up to 4 members
For installation in houses, where otherwise long hot water and circulation pipework would be
necessary.
For installation in apartments and holiday houses.
Wall-mounted versions – simple installation, little space is necessary.
Ducted air – enables suction of the inlet air from different spaces and outlet of the cooled air back into
the same spaces or into the surroundings.
In the summer, the heat pump provides the cooling of spaces and by exploiting waste heat during
winter it enables the ventilation of spaces and elimination of moisture.
External large-surface condenser is placed on the outer side of the water tank, thus preventing the
accumulation of limescale on heating elements and ensuring a long lifespan and a long-lasting
efficiency, without unnecessary cleaning of the condenser.
Highly efficient rotary compressor enables a fast and silent operation; in connection with other
elements, it also guarantees high energy efficiency.

Excellent choice for every house!
COMPACT HEAT PUMPS
Compact types of HP for tap water heating are installed on 230
and 300-litre hot water tanks, which are coated with high-quality
enamel according to DIN 4753 (enamel is fired at 850°C until it fuses
with the basic material) and have a built-in Mg anode.
Thickness of the closed-cell PU insulation is 50 mm with a silver tinplate covering. The compact heat pump
is placed in a suitable room (e.g. boiler room, garage, storage room or basement), where we wish to achieve
a cooling effect (4 to 5°C). Water pipework, which enables the inlet of cold water and outlet of hot water, is
connected to the water tank. Additional heat exchanger, integrated in all heat pumps, can be used during winter
to heat tap water by means of a boiler. All compact heat pumps are also fitted with connections for the circulation
pump to heat water with a back-up source – boiler. Solar versions (S) have two additional heat exchanger.
These heat pump versions are also equipped with a rotary compressor, which enhances the heat pump’s energy
efficiency and prolongs its lifespan. An automatic anti-legionella programme is built-in as well. The water heaters
are fitted with an external large-surface heat exchanger, which reduces the accumulation of limestone.

Standard heat pumps
Compact heat pumps for large consumers
Heat pumps are fitted with an electronic
thermostat, which can be used to heat
water to the temperature of
60°C. To activate the legionella
protection, we simply press the
function key. These heat pumps
represent a good ratio between
the efficiency and price of the
heat pump.
Such heat pumps are intended for larger consumers of domestic hot water. They are thus
intended for those who waste over 300 l of water on a daily basis, such as: restaurants and
bars, apartments, hotels, schools, kindergartens, sport societies, etc. In such
cases, not only daily water consumption must be determined, but also the final
consumption of water – for instance in the course of one hour. This particular
data namely helps us choose the appropriate volume of the water heater.
450-litre water heaters are fitted with a hard, 50 mm thick PU insulation and a
built-in protection Mg anode. The heat pump must be installed in a room, large
enough to provide a sufficient amount of heat. If there is enough waste heat in a
room, then the size of the room is not relevant in itself.

Use the benefits of excess heat!
HEAT PUMPS WITH AIR DUCT SYSTEM
Heat pumps with air duct system enable not only the preparation
of hot domestic water, but also the cooling of selected spaces. Air
ducts (pipes) run from the point of the air intake, through the heat
pump to the point, where the air is discharged. The overall length of
the duct system cannot exceed 10 m. The heat pumps also have an
integrated function (antilegionella programme) to activate periodical
overheating of tap water to 60°C (heating with compressor).
These heat pumps are also equipped with an external large-surface condenser and a highly efficient rotary
compressor, which was developed especially for tap water heat pumps. Compared to piston compressors, the
energy efficiency of rotary compressors is over 30% higher. What is more, the very construction of the rotor
guarantees still operation and a faultless start-up even after several months of stand-by mode, which ensures a
long lifespan of the device. A thermal expansion valve is built-in by the manufacturer as well. All these advantages
guarantee an extremely high COP value of 3,7. An integrated 1,5 kW electric heater is optional. The “OPTITRONIC”
regulation is installed in all heat pump versions.
>> Cooling of a neighbouring room.
Low-temperature HP, capable of operating even at -10°C
(NT versions)
>> Air intake from a neighbouring room.
Air duct heat pumps for large consumers
If we wish to heat tap water even when the temperature of the inlet
air drops under +7°C, then a HP type with defrost function, capable
of operating even at -10°C of the inlet air, is available. Of
course, simultaneously with the inlet air temperature drop,
the heating capacity of the heat pump decreases as well,
in which case we can additionally activate the built-in
electric heater. Low-temperature heat pumps are especially
convenient for installation in passive and low-energy
houses, where the extraction of the outside air is possible.
Heat pumps of large capacities require a considerable amount of
waste heat in order to operate effectively and without disturbance.
Since we do not always have a room large enough at disposal, the
warm inlet air can be supplied from other rooms, while
the cold outlet air is discharged into the surroundings.
If tap water is heated solely outside the heating season
(mainly summer holiday apartments or various tourist
facilities) then the ambient air is sufficient for the
operation of the heat pump. Inside the building we only
need a small room for the installation of the device.
450-litre water heaters are fitted with a hard, 50 mm
thick PU insulation and have a built-in protection anode.

Energy-saving heating – make use of an existing water heater!
INDEPENDENT HEAT PUMP UNITS
FOR TAP WATER HEATING
Heat pumps for tap water heating – without the water heater
If you already have an installed water heater (200 litres or more), an independent heat pump unit can be attached to the existing heating system.
First the heat pump unit is installed into a room that we wish to cool. Then a water connection – R 1/2” (or more for over 2 kW of power) of up to
15 m is established between the heat pump and the water heater. The connection system also includes a circulation pump, an expansion vessel
and a safety valve.

Heat is the source of comfort
With the classic radiator heating we heat the indoor air, while the floor and wall heating warm up the body. If floor heating is combined with
a heat pump, we can achieve a pleasant, warm feeling already at a 2°C lower temperature. Lower temperature means, of course, that the heat
necessities are reduced by 5 to 8 %, which additionally increases your savings. Since the operation of heat pumps is almost soundless, you can
easily indulge in the new comfort.
No extra cleaning or acquiring of space
By installing a heat pump, worries about oil or gas supply are gone forever. You will never have to clean your furnace or stove again, or measure
emissions. Only a regular yearly inspection of the system is recommendable, carried out by our experts. The installation is also very simple, since
only a smaller room is necessary for the placement of the heat pump and no chimney.
Cooling in hot days
Certain types of heat pumps also enable the cooling of spaces. All air-source heat pumps are available in reversible version and enable space
cooling. Water-source and ground-source heat pumps have a passive cooling station for space cooling, where energy is only needed for the
operation of the circulation pump.
Subsidized purchase
Due to numerous advantages, most countries allocate subventions for the purchase of such heating systems. The investment costs therefore
generally do not exceed the costs for the purchase of comparable, classical heating systems. By the help of such support, it is possible to buy
such heating system with the savings from the heating alone.
Eco-friendly operation
Heating with fossil fuels (oil, gas) causes an enormous quantity of dangerous and harmful emissions, such as sulphur dioxide (SO2), carbon
dioxide (CO2), soot, etc. All harmful emissions, especially CO2, encourage and increase the greenhouse effect, which is substantially altering
our climatic conditions. Consequently, hailstorms, floods, long-lasting periods of heat and drought, colder or warmer winters, etc are more
and more frequent. To preserve our environment for future generations, we must think in advance and consider the future today by gradually
reducing the release of emissions into the atmosphere. By using heat pumps we are able to make one step forward, since they are one of the
most ecological heating systems.
The future is secured
The energy that is needed for a heat pump is right outside your door in the surrounding area, while other, standard energy sources like oil
and gas are further away and depend on world crises of the economic systems. Those sources are limited by their quantity and accordingly,
with the reduction of supplies, the prices of these energy sources constantly grow. A heat pump, on the other hand, assures you safe future by
exploiting the energy from purely natural sources and, above all, guarantees acceptable costs.

WHICH HEAT SOURCE TO CHOOSE – WATER, GROUND OR AIR?
The one that is available and has at the same time the highest average annual
temperature. From the energetic point of view, the most favourable energy source
is certainly ground water, if it is available in sufficient quantity and quality, since its
average annual temperature is around +10°C. Such systems can reach a COP of over
5 – this signifies the highest savings.
If there is no ground water at disposal, but there is an area of sufficient size that is available, then this source can be exploited by placing a
horizontal collector or a vertical probe. Such systems can reach a COP value of about 4. If, however, none of the previously mentioned energy
sources are at disposal, we can still exploit the outside air as the heat source, which is available in unlimited quantities. Air-source systems can
reach a COP of over 3,5 and in the coastal area even over 4.
What is the recommended heat pump capacity?
For new buildings, the heat pump capacities are calculated already in the construction plan. They depend mainly on the size of the building and
the quality of the insulation. Thus, the required heating capacities of new buildings with quality insulation generally do not exceed 50 W per m2
of the heating area + 200 W per person for tap water heating (houses with heat recovery require max. 35 W/m2). Insofar the calculation of the
heating needs in an existing building has not yet been made, the easiest way to do that is on the basis of the annual consumption of oil or gas
used for heating. An example of such calculation is given in the table below.

Which heating system should you chose?
If you are starting to build a house, then there is only one decision – choose a low-temperature heating system, i.e. floor heating (which also
signifies the highest housing comfort) in all spaces. In addition to the floor heating, you can also install for example bathroom radiators or
convectors, if you also intend to cool the spaces. The important thing is, that this additional equipment cannot cause the inlet temperature to
increase. The lower the required inlet temperature in the system, the higher the COP value and by that savings of the heating costs are reduced
as well. If the temperature of the inlet water increases by 1°C, the consumption increases by 2,5 %.
In case you have an existing building with installed radiators, it is of course possible to use these radiators, however the heating costs will not
be reduced as much. In such buildings with an existing radiator system, the installation of high-temperature heat pumps is recommendable. In
certain cases we can also choose a low-temperature heat pump, but we must be sure that the required inlet temperature does not have to be
higher than 55°C.

The heat of the air is immense!
AIR/WATER HEAT PUMPS
Even cold air is full of energy
The air is an inexhaustible source of energy and it can be found everywhere. The latest versions of air/water heat pumps allow the heating at
an outside air temperature of -25°C. Even at a very low air temperature the COP is still higher than 2, which represents 50% of energy savings.
There is no need to bore a well or to install a horizontal collector; therefore these types of pumps are the cheapest. Even the installation and
maintenance are easy and inexpensive. According to statistic data about temperature changes, it can be concluded that there are only few days
with the temperature below -5°C, which means that the annual performance factor of these pumps is above 3.5.
Recommended ways of building a heating system
These types of heat pumps are usually planed in such a way that they alone cover all the heat losses of a building up to -5°C of the outside air
temperature. Below this limit, the heat pump can work together with another heat source. More than 98% of heat needs are covered in such a
way. As another heat source, an electric heater is usually used in new buildings, yet in existing buildings with a good conventional heat source
only this can be used. An electric control system enables a simple positioning of a bivalent point – this is the point of switching to another heat
source.
>> A HP independently heats a house with a floor heating and tap water
!
Advantages of air/water heat pumps:
compared to systems ground/water and water/water, low investment costs
are crucial, since there is no need to build a primary system (a collector or
wells)
a simple and inexpensive installment and further maintenance of the
system (all parts are easy to get)
a small room required for the system and its installments
no special licenses required for the building

Silent and simple!
COMPACT AIR/WATER HEAT PUMPS FOR
OUTDOOR INSTALLATION
The installation of these heat pumps is very simple, since they are placed entirely
outside a building. They are particularly convenient for smaller houses, where the
space for a boiler room is generally very limited.
Heat pumps are placed on a concrete support, through which insulated hot water connecting tubes are led to the heating system in the boiler room.
Additionally, an electric lead wire and communication wire (UTP) to the electric control system in the boiler room is needed as well.
The operating range is from -20°C to +35°C. The maximum temperature of the heated water is 55°C.

When radiators are not a problem anymore!
HIGH-TEMPERATURE
HEAT PUMPS AIR/WATER
Living in a house with a conventional heating system (oil, heating gas, etc.)
makes you aware of high heating costs. If you are able to reduce these costs
for more than 50% while heating with heat pumps, then you will use this
opportunity for sure.
You might have heard that this is impossible, if you heat your house with radiators. Yet this
is not the case. All you have to do is to choose a suitable heat pump. High-temperature heat
pumps, reaching the temperatures of the inlet water higher than 65°C that are suitable for
houses with radiators. It is true that the efficiency of heat pumps at such high temperatures
is somewhat lower, however, you do not need to heat so much, since you have an integrated
weather-controlled regulation, adjusting the necessary water temperature according to the
outside air temperature. This means that you will need the highest water temperature only in
10 to15 coldest winter days.

Termotronic TT - 3000
Super EVI
High-temperature heat pumps have a built-in special EVI compressor
and an additional heat exchanger, which makes the following
possible:
to reach high heating temperatures (65°C)
to work at very low outside air temperatures (-25°C)
the minimum reduction of power at lower outside air temperatures
and at higher temperatures of the heating water
the improvement of energy efficiency of a HP at conditions stated
above (compared to low-temperature HP)
Weather-controlled heat pump regulation ensures a desired
temperature in a house all the time by working with the lowest
possible temperature of heating water. Only in this way the highest
possible annual COP can be achieved – representing higher savings
and reduced heating costs.

Energy from a home garden!
HEAT SOURCE – GROUND
Ground/water heat pumps
Ground-source heat pumps exploit thermal energy stored in the rocks or soil. An enormous amount of solar energy that is stored in the soil can
easily be used for space or tap water heating. The amount of solar energy that can be extracted from the soil depends on the composition of
the soil, on the heat pump capacity, and the manner of the source exploitation (horizontal collector or vertical probe). The energy is extracted
by means water (+ antifreeze agent) which circulates in a closed piping system laid at a depth of 110 – 130 cm (horizontal collector); in case of
a vertical probe, the tubular probes are placed into boreholes at a depth of 60 – 140 m. the circulating water transfers heat to the heat pump,
which transforms this heat to a higher temperature level (to 55°C) by the help of added electrical energy; the returned water is cooled by
approximately 4°C).
Horizontal ground collector
If there is enough land not build on at disposal (around the house or in the immediate vicinity), a horizontal collector is the best decision. Regular
PE pipes are placed at a depth of approximately 120 cm, the distance between individual pipes being 70 cm. the required length of the pipes
depends on the quality of the soil. The more humid the soil, the more heat can be extracted from it and therefore the length of the pipes is
shorter. Usually, the average is used for the calculation – that is 20 W/m of pipes (for a 10 kW heat pump about 500 m of pipes is needed). If the
soil is sandy, the factor is only 10 W/m.
The required surface (in m2) = approximate heating capacity of the heat pump (in kW) x 35 or approximately 2x heating area of the building (the
exact area is defined during the excavation works).
Vertical probes
If there is not enough land available for a horizontal collector, the drilling of boreholes and exploitation of the rocks is possible. The length of the
probe depends on the heating capacity of the installed heat pump. Required length of the probe (in m) = approximate heating capacity of the
heat pump (in kW) x 14 (this is an approximate calculation – the exact length is defined when drilling

The most efficient heat source!
HEAT SOURCE – UNDERGROUND WATER
Living with the groundwater energy
Ground water is a very suitable energy source for the exploitation with a heat pump. Its main advantage is a relatively constant temperature
level (between +7 and +12°C). To be able to exploit ground water we need to drill two boreholes into the ground – one for the extraction of
water and one to return the water into the ground. A submersible pump into the extraction well pushes the water through the heat pump,
which then extracts thermal energy from the water, and returns it (cooled by a few °C – from 2 to 4) back into the ground through the second
borehole, which is about 15 to 20 m away. The amount of water in the borehole must be sufficient for continuous operation even at the highest
heat necessities. To extract ground water we need a water permit and a chemical analysis of the water before any work is done. Due to a
relatively high temperature, the ground water is an ideal heat source with the highest energy efficiency (based on the annual average), since it
reaches a very high COP.
Water-source heat pumps are able to produce large heating capacities even in case of small outdoor dimensions. A special plate heat exchanger
made from stainless steel contributes to the robust and innovative construction.

Passive cooling
Passive cooling is possible with
water-source HP and ground-source
HP with a vertical probe. The cooling
is performed by pumping the cold
source (groundwater, water stored in
a probe) through an intermediate heat
exchanger that cools water for the
room cooling. The cooling of spaces
is usually performed with the help
of convectors (most effective), which
also reduce humidity, or by means of a

Large consumers have the highest savings!
HEAT PUPMS OF LARGE CAPACITIES
In order to heat large buildings, we need heat pumps with large heating capacities.
This can be achieved by linking together several small heat pumps into a cascade or
by simply choosing a large capacity heat pump.
Heat pumps (reversible designs) can also be used for cooling. In case of a smaller need for cooling, only passive cooling is possible as well
(water-source heat pumps or ground-source heat pumps with vertical probes). If we exploit surface waters or if the quality of the ground water is
insufficient, an additional heat exchanger must be built in.
