Air source heating pumps absorb heat from the outside air. This heat can then be used to heat a variety of things in your house ranging from the basic radiators and hot water to underfloor heating systems, or warm air convectors. The air source heat pump will be able to extract the heat from the air similar to the way that fridges extract heat from its inside. Heat can be extracted from the air from temperatures as low of -15° C. Overall, heat pumps will have some impact on the environment as they still need electricity to run, but the heat they extract from the ground, air, or water is constantly being naturally renewed.
What are the benefits of using Air heaters?
It will lower your fuel bills this winter, especially if you are replacing conventional electric heating. It could also become a potential source of income for you through the UK government’s new Renewable Heat incentive. Your carbon footprint will drop significantly dependant on which fuel you are replacing. There are also no fuel deliveries needed which will save you both time and a lot of money. It can heat both your home and your water, again saving money and with its simplistic design, minimal maintenance is required. And it is easier to install than a ground source based heat pump.
The main difference between gas/oil boilers and air heaters is that the heat pumps deliver heat at lower temperature over longer periods of time which can be useful in the winter when homes need to be constantly heated. The radiators might not feel as hot to touch as with gas and oil boilers due to this lower heat emission.
How do air heaters work?
The heat from the air is firstly absorbed at a low temperatures and converted into a fluid. It is this fluid that is then passed through a compressor where its temperature is then increased and transferred to the heating system or the hot water circuit within the house. Because of this, there are two main systems; air to water and air to air. The Air to water system will distribute heat through the wet central heating system in the house. This system is ideal for under floor heating or larger radiators as they emit a lower temperature for large periods of time. The air to air system is different in that it produces warm air which is able to circulate by fans to heat your home.
