Air To Water Heat Pump Efficiency

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.

Air to water heat pump efficiency.

Air to water heat pump systems. 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. I recently ran an analysis of two heat pumps. A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater.

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. However ground water heat pumps are more efficient. 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. 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 benefits. 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. 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. 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.

An ashp works a bit like a refrigerator in reverse. 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. 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. This type of heat pump works best in moderate climates.

Using this scale commercial air source heat pump efficiency can be as high as 4 whereas ground source heat pumps can reach up to 5. Connecting solar collectors to the heat pump system further increases efficiency and savings. Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days.
