How Do Air Source Heat Pumps Work? Your Guide to Sustainable Heating in London & The South East
As the UK transitions to cleaner energy, more homeowners are looking for sustainable alternatives to traditional heating systems. One technology that’s gaining traction—particularly across Greater London, Kent, and the South East—is the Air Source Heat Pump (ASHP).
At Harvard Renewables, we believe in educating our customers on the technology we install, so they feel confident in making environmentally and economically sound decisions.
In this article, we’ll explain exactly how Air Source Heat Pumps work, why they’re so effective, and what to consider when choosing a system.

What Is an Air Source Heat Pump?
An Air Source Heat Pump is a low-carbon heating system that captures thermal energy from the outside air—even when it’s cold—and converts it into heat for your home and hot water. It works similarly to a refrigerator, but in reverse. Instead of pushing heat out, it draws warmth in and amplifies it.
Here’s a simple breakdown of how the process works:
- Heat Absorption – The system draws in outside air and passes it over a refrigerant fluid.
- Compression – The fluid is compressed, raising its temperature.
- Heat Exchange – The now-warm fluid is used to heat water or air that circulates through your home.
- Distribution – This heat is delivered via underfloor heating, radiators, or a hot water cylinder.
Because the system uses electricity only to power the heat pump, and not to generate heat itself, it’s incredibly energy efficient—delivering up to three times more heat energy than it consumes in electricity.
