Air-water heat pumps are the sustainable replacements for
current gas boilers.
Heat pumps are known for their extremely high efficiency and
environmentally-friendly characteristics. The system is at least
four times more economical than a conventional gas boiler and emits
considerably less CO2.
The air-water heat pump effortlessly supplies hot water for central
heating and sanitary purposes the whole year round – and provides
cooling in the summer. Air-water heat pumps extract more than *5%
of the energy consumed from the outdoor air (to **0 °C). As a
result of the split setup of the heat pump,
the outdoor unit can easily be installed in the garden, on the
patio or on a flat roof. There is often enough room for the indoor
unit (the hydrokit) in a storeroom, the garage or the existing
boiler room. The coolant pipes between the two appliances will
bridge a distance of as far as *0 metres.
The efficiency of a heat pump is expressed as its Coefficient of
Performance (the ratio of the useful heat to the energy input,
COP). Because DUWACO’s air-water heat pumps heat water on the
basis of a low temperature, a high COP value is achieved (the lower
the water temperature, the higher the COP value). In practice,
water of an average temperature of *5 to *0 °C is delivered.
Heat pumps achieve the highest COP values if they are used in
combination with wall and floor heating.
DUWACO supplies two models of air-water heat pumps, the
specifications of which are given below.
The advantages of air-water heat pumps are as follows:
- up to *0% more economical with regard to energy costs than
natural gas systems (in combination with solar panels, the savings
may even be as high as *5%!);
- *0% cheaper than a system that uses ground drilling;
- yield extra savings as a gas connection is no longer
needed;
- top efficiency, 4 times more than the best condensing
boilers;
- no fire or CO hazard;
- multifunctional, since the system can be connected to wall and
high efficiency radiators;
- contribute to a large reduction in CO2 emission and other
harmful substances;
- double function: heating in the winter, cooling in the
summer;
- *-year manufacturer’s warranty;
- the *-year manufacturer’s warranty can be extended by a
maintenance contract of 5, 8, *2 or *5 years
