Air to water heat pump efficiency.

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. A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater. 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. 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.

Air to water heat pump systems. I recently ran an analysis of two heat pumps. However ground water heat pumps are more efficient. Keeping the working principles of an air to water heat pump in mind the decline in temperatures will affect the operating efficiency.

Air to water heat pump benefits. 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. This type of heat pump works best in moderate climates. 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.

An ashp works a bit like a refrigerator in reverse. 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. Connecting solar collectors to the heat pump system further increases efficiency and savings. 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.

Types of air source heat pumps there are two main types of air source heat pumps ashps. 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. Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days.
