The heat pump draws free energy from the air and uses it to heat and cool the building or prepare domestic hot water.

Air source heat pumps have gained popularity in domestic heating owing to their efficiency and sustainability. These pumps work by drawing warmth from the outdoor air and using it to regulate indoor temperatures, making them a suitable option for both new and existing homes. The use of renewable energy sources like heat pumps allows homeowners to achieve cost-effective and dependable heating while decreasing their carbon footprint. Investing in heat pumps is an excellent way to introduce sustainable heating solutions into homes and represents a wise choice for those seeking a dependable and cost-effective heating alternative.


Q&A on air source heat pump

  • Q. Will a heat pump provide all the heat you need in the winter?

    A. Heat pumps generally become less effective below ambient temperatures of 35 to 40 degrees Fahrenheit. Below that, it may be necessary to replenish the heat provided by the heat pump.

  • Q: How expensive are heat pumps?

    A: The initial cost of heat pump equipment can be 10-15% more than a unit that uses natural gas or LP Gas for heating, but the difference is minimal compared to the cost of a natural gas or LP Gas service setup.

  • Q: Do the heat pumps have to exchange heat with the outside air?

    A: No. Different models of heat pumps can exchange heat with ground water, making them less susceptible to external air temperatures..However, ground water heat pumps are somewhat more expensive to install.

  • Q: How do I know if my electric heat is on when I use my heat pump?

    A: Most heat pump thermostats have a small light or icon that lights up when the supplemental electric heater is in use.

  • Q: On really cold days, my heat pump sometimes has steam coming out of it..Why?

    A: When this condition occurs, your heat pump is going through a "defrost" cycle. Outdoor coils can freeze over on cold, wet days..When this occurs, the defrost control senses it and automatically initiates a defrost cycle. To perform defrosting, the reverse valve is switched on, and the unit is effectively in cooling mode for the time being..The hot refrigerant gas now flowing through the outdoor coils melts away the ice, and the resulting steam is created by the evaporation of the water..A defrost can last from one to 10 minutes, depending on the unit and conditions..Electric supplemental heaters are automatically activated during this time to temper the indoor air..Expect slightly cooler discharge air during this period.
