Air Source

Air source heat pumps are a form of low carbon heating, they use the outside air to heat or cool your home. If you are switching from a coal or an electricity-based heating system, you can significantly reduce your carbon emissions. 

Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s important that your home is well insulated and draught-proofed to minimise heat loss. 

The term air source heating might seem odd. After all, the cold air outside is the reason most of us need heating in the first place. How can outside air possibly be used to heat our homes? 

The answer is by using a simple and effective technology which is both energy efficient and good for the environment too. Air source heating is growing in popularity thanks to its relatively low upfront costs, green credentials, and the prospect of saving money on your heating bills. 

Here’s how the process works – 

The main device used by an air source heating system is the air source heat pump. This is fitted to the outside of your home. It is usually fitted to the side or the back of a property. The air source heat pump itself looks like an air conditioning unit.  

The air source heat pump sucks in air from outside to heat a liquid refrigerant. It then uses electricity to power a pump which compresses this liquid to increase its temperature. This is then condensed back into a liquid to release the stored heat. 

This heated liquid is then pushed around your home either through radiators or via an underfloor heating system. Any liquid that is left-over is used in a hot water cylinder. This stored hot water can then be used for washing, showering, or bathing. It is a remarkably simple process. 

Air source heating systems are environmentally friendly and cost-effective and can provide you with both domestic heating and hot water. They are simple to install and apart from using a small amount of electricity have no carbon footprint at all.
