Air To Water Heat Pump In Floor Heating

An air to water heat pump typically costs 50 to 60 less to heat your home than a tradition fossil fuel system such as an oil or gas boiler.

Air to water heat pump in floor heating.

The ashp absorbs heat from the outside air into a liquid at a low temperature then the heat pump compressor increases the temperature of that heat. Air source heat pumps are a highly efficient way of heating your home providing a renewable energy alternative for homeowners. For example at 20f outdoor temperature a distribution system that can deliver the heating load of the building using 110f water would allow the heat pump to reach a cop of about 3 1 whereas a. Radiant floors typically require between 110 120 f supply temperature and larger systems can be as low as 80 90 f.

This is especially true for cop. In the condenser the hot liquid s heat is transferred to your heating and hot water circuits. Most home owners are familiar with the advantage of radiant floor heating versus centralized forced air heat but most home owners including builders have no idea that radiant floor cooling is possible and can be very cost effective for those building a home with hydronic heat. A geothermal heat pump would be an excellent heat source for radiant in floor heating particularly our w series heat pump.

Put simply the efficiency of an air to water heat pump is from 320 to 400 or more where as even a condensing boiler has an efficiency of only 92. The heat pump disconnect switch hpds must be closed to provide power to the heat pump. New build projects low temperature air to water heat pump. The lower the better the graphs in figures 2 and 3 imply the advantage of combining the air to water heat pump with a low temperature heating distribution system.

The air to water heat pump and circulator p1 are powered by a dedicated 240 120vac 30 amp circuit. How much you ll save depends on local propane and electricity rates but a geothermal heat pump is around 350 efficient while a propane boiler would be less than 100 efficient. Air to water heat pump benefits. Air to water heat pumps can even generate enough energy for you to earn money from them through the government s renewable heat incentive rhi scheme.

One of the most often overlooked areas of a hydronic air to water heat pump is the ability to cool as well as heat. Always verify the specific wiring requirements for the heat pump being used and ensure it is coordinated with the balance of system wiring. This low temperature system is a perfect combination for underfloor heating low temperature radiators or fan coils. The reason is simple the lower the design temperature the higher the performance of a heat pump.

Perhaps the best matched heating system for any heat pump is radiant floor hydronic heating.
