Installation Guide to Air Source Heat Pumps for Homeowners
Air Source Heat Pumps
Air source heat pumps (ASHPs) are rapidly becoming a popular choice for homeowners seeking to reduce their carbon footprint while keeping energy bills manageable. These systems provide an energy-efficient solution to both heating and cooling needs. Unlike traditional heating methods, which often rely on fossil fuels, air source heat pumps extract heat from the outside air, even in cooler temperatures, and transfer it indoors. This process allows them to heat a home efficiently and with minimal environmental impact. While typically used for heating in colder months, air source heat pumps can also work in reverse, cooling the home during warmer weather, making them a year-round solution.
What is an Air Source Heat Pump?
An air source heat pump is a device that transfers heat from the outside air into your home or vice versa, depending on the season. The technology behind ASHPs is similar to that of a refrigerator, except it works in reverse. It extracts heat from the outside air (even when it’s chilly) and uses a refrigerant to transport the heat inside, where it is released into the home. This process makes it an extremely efficient way to heat a home. During warmer months, the process can be reversed, and the ASHP can act as an air conditioner, drawing heat out of the home and cooling it down.
