Heat pumps work by moving heat from one location to another using a small amount of energy
An air source heat pump (ASHP) takes warmth from the air outside and uses it to heat the water for your central heating system.
Air-source heat pumps are much more efficient than a gas boiler and will provide effective central heating without the emissions that come from burning fossil fuel in your home.
How the does an Air-Source Heat Pump work and whats make it super-low carbon?

There’s a number of system options, but the premise is the same: an air source heat pump takes heat from the air and boosts it to a higher temperature using a compressor. It then transfers the heat to the heating system in your home. Think of it like a fridge in reverse.
It’s a tried and tested technology, used widely across the world. The biggest user of heat pumps is Norway – demonstrating that the system works even when the temperature outside is seriously cold.
Step 1
External air – Air is drawn into the unit from the outside.
Step 2
Refrigerant tubes – The air passes over tubes filled with refrigerant.
Step 3
Compressor – The refrigerant warms up and turns from a liquid into a gas.
Step 4
Heat exchange – The hot gas now goes into a heat exchanger warms the water for your home heating system.
Step 5
Return to liquid – The refrigerant condenses back into a liquid and returns to the start of the cycle.
