How An Air Source Heat Pump Works

Using an air source heat pump to heat your home is more eco-friendly, more energy efficient, and can be highly cost-effective. Essentially, when using an air source heat pump, you can make your own - renewable - energy, thus saving money.
When you use an air source heat pump, the heat will be delivered to your home at a lower temperature than using an oil or gas boiler. Although this means such a pump will have to be run for a longer time to get up to the right temperature, it is still cheaper than using other kinds of heating. If you need to replace your boiler, a great way to make it more affordable to run would be to ensure the new boiler can use an air source heat pump. Of course, you'll still need to ensure your home is adequately insulated, otherwise you'll lose more heat than usual, however.
The air source heat pump uses a compressor that takes heat from the air and raises its temperature. Once it reaches the right temperature, the energy will be transferred to your heating system; this is essentially the opposite of how a fridge works. To get to the right temperature, the warm air is first turned into a cool liquid refrigerant, compressed, heated up, and turned back into liquid once it reaches a specific temperature. This liquid is your fuel which runs through your boiler and allows you to heat your home and hot water. You can safely store anything you don't use.

You will need to use energy to make the pump work since it requires power, but when you offset this energy cost against the savings you can make using the air source heat pump, you should still save money using this eco-friendly method of heating a property.
