Air To Water Heat Pump Efficiency

Air water heat pumps are otherwise similar to air air heat pumps but they transfer the extracted heat into a water heating circuit floor heating being the most efficient and they can also transfer heat into a domestic hot water tank for use in showers and hot water taps of the building.

Air to water heat pump efficiency.

Many high efficiency heat pumps are equipped with a desuperheater which recovers waste heat from the heat pump s cooling mode and uses it to heat water. Heating efficiency for air source electric heat pumps is indicated by the heating season performance factor hspf which is the total space heating required during the heating season expressed in btu divided by the total electrical energy consumed by the heat pump system during the same season expressed in watt hours. Air to water heat pump benefits. This means that for every unit of electricity you put in the heat pumps have the potential to produce 4 and 5 units of heat respectively.

Air to water heat pump systems. Many air source heat pumps are eligible for payment through the renewable heat incentive a government scheme that provides payments to homeowners who generate their own heat. However ground water heat pumps are more efficient. An ashp works a bit like a refrigerator in reverse.

The efficiency of an air to water heat pump is most optimal at 7 c as opposed to dry and cold locations where outside temperatures fall below 20 c. Keeping the working principles of an air to water heat pump in mind the decline in temperatures will affect the operating efficiency. Types of air source heat pumps there are two main types of air source heat pumps ashps. 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.

Work with an efficiency excellence network contractor to install your heat pump and get up to 6 000 back plus a 500 bonus for income eligible vermonters. This type of heat pump works best in moderate climates. A geothermal heat pump with an assumed seasonal average cop of 4 0 and a cold climate air to water heat pump with a seasonal average cop of 2 5. Not only do daikin heat pumps offer economical heating of residential and commercial settings they can also provide a total solution for domestic heating and hot water supply.

A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater. Connecting solar collectors to the heat pump system further increases efficiency and savings. 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.
