Air To Water Heat Pump Efficiency

This type of heat pump works best in moderate climates.

Air to water heat pump efficiency.

Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days. 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 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. An ashp works a bit like a refrigerator in reverse.

Air to water heat pump systems. I recently ran an analysis of two heat pumps. 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. 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. 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. 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. 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.

A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater. Keeping the working principles of an air to water heat pump in mind the decline in temperatures will affect the operating 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. 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.

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