Air Source Heat Pump Water Heaters

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

Air source heat pump water heaters.

Install them in a space with excess heat such as a furnace room. Cool exhaust air can be exhausted to the room or outdoors. That means that a hpwh cools the space where it is located. 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.

I recently ran an analysis of two heat pumps. Using an air source heat pump heat pump water heaters hpwhs extract heat out of the air where they are located to heat the water. That s a good thing in the summer it doubles as air conditioning but in the winter it s not so helpful. That s why you get the most out of it when you pair it with an air source heat pump because they are a very efficient heat source when combined.

However this is not the only reason that our heat pumps are industry leading for hydronic heating and cooling applications. The system consists of a standard single speed air source heat pump sized to the heating load rather than the usual smaller summer cooling load. Heat pump water heaters require installation in locations that remain in the 40º 90ºf 4 4º 32 2ºc range year round and provide at least 1 000 cubic feet 28 3 cubic meters of air space around the water heater. These units range in capacity from 25 000 btu to 250 000 btu generating 50 to 550 gallons of hot water per hour.

An air to water heat pump water heater uses the air in the house to generate hot water so the more efficient the air heating system is the more efficient the hot water heater will be. Connecting solar collectors to the heat pump system further increases efficiency and savings. They absorb heat and transfer it to another medium. Air source heat pump water heaters an energy and cost saving option air source hpwhs remove hot humid air from laundries or other high heat areas cooling those areas while essentially providing free water heating energy.

The heat pump is connected to a large heavily insulated tank of water that the heat pump heats or cools depending on the season of the year. Heat pumps work similarly to a refrigerator. Air source heat pump and solar water heating combined the arctic heat pump is already the most energy efficient air source heat pump for cold climates on the market in north america.
