How do Air source heat pumps (ASHP) work?
Posted on February 16th, 2023 by James Eades
Air source heat pumps (ASHPs) have gained popularity in recent years as an alternative heating source for homes and buildings. ASHPs use the principles of heat transfer to extract warmth from the air outside and transfer it to the interior of a building. In this article, we will explore how an air source heat pump works and its benefits as a heating source.
What is an Air Source Heat Pump?
An air source heat pump is a heating system that extracts heat from the air outside and transfers it into a building. It does not generate heat, but instead concentrates it and moves it from one location to another. ASHPs consist of two main components: the outdoor unit and the indoor unit. The outdoor unit contains a fan, compressor, and heat exchanger,
How Does an Air Source Heat Pump Work?
During the heating cycle, the outdoor unit draws in the air from outside, which flows over the heat exchanger. The heat exchanger contains a refrigerant that absorbs the heat from the outside air and becomes a gas. The compressor then compresses the gas, which raises its temperature. The hot gas is then transfers its heat to your heating system via the heat exchanger.
Why is an Air Source Heat Pump an Excellent Choice for Your Home?
There are several reasons why an air source heat pump is an excellent choice for heating your home. Firstly, ASHPs are highly energy-efficient, which means they can provide heat using less energy than traditional heating systems. This can result in lower energy bills and reduced carbon emissions.
Secondly, ASHPs are versatile and can be used to provide heat in a variety of settings. They can be used for underfloor heating, radiators, or as part of a bivalent central heating system.
Finally, ASHPs are easy to install and maintain they have fewer moving parts than traditional heating systems, which can reduce the risk of breakdowns and maintenance costs.
Air source heat pumps are an innovative and cost-effective heating solution for your home. They work by extracting heat from the outside air and transferring it inside, which makes them highly efficient and environmentally friendly. If you’re considering replacing your traditional heating system or looking for an energy-efficient alternative to heat your home, an air source heat pump is an excellent choice. It provides warmth throughout the year and is easy to install and maintain, making it a convenient and practical option for any home or building.
