Air To Water Heat Pump Efficiency

Air to water heat pump benefits.

Air to water heat pump efficiency.

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. 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.

A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater. 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. Connecting solar collectors to the heat pump system further increases efficiency and savings. An ashp works a bit like a refrigerator in reverse.

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. This type of heat pump works best in moderate climates. Types of air source heat pumps there are two main types of air source heat pumps ashps. Keeping the working principles of an air to water heat pump in mind the decline in temperatures will affect the operating 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. I recently ran an analysis of two heat pumps. 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 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.

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. 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. Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days.
