Air To Water Heat Pump Efficiency

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.

Air to water heat pump efficiency.

This type of heat pump works best in moderate climates. 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. 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. 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.

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. An ashp works a bit like a refrigerator in reverse. A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater. Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days.

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

Connecting solar collectors to the heat pump system further increases efficiency and savings. 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. 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. 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.

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 benefits. I recently ran an analysis of two heat pumps.
