The Technology

How an air source heat pump works

Simple technology, proven over decades. Here's what happens inside the unit.

1

A Fan Draws in Outside Air

The outdoor unit pulls air across a heat exchanger. Even at -20°C, there's usable heat energy in the air.

2

Refrigerant Absorbs the Heat

A refrigerant liquid circulates through the heat exchanger, absorbing warmth from the air and turning into a gas.

3

A Compressor Concentrates It

The compressor squeezes the gas, raising its temperature significantly — the same principle as a fridge, but in reverse.

4

Heat Goes to Your Home

The hot gas passes through a second heat exchanger, transferring heat to your radiators and hot water cylinder. For every 1kW of electricity used, you get 3-4kW of heat. No boiler comes close.

Compatibility

Works with your existing system

You don't need to rip out your current heating. An air source heat pump connects to what you already have.

  • Radiators — work fine with a heat pump. Some may need upsizing for optimal performance at lower flow temperatures. We check every radiator during the survey.
  • Underfloor heating — ideal pairing. UFH runs at low temperatures naturally, which is exactly what a heat pump delivers most efficiently.
  • Hot water — a hot water cylinder is included with every installation. Your domestic hot water is heated by the same system.

Frequently asked questions

Straight answers to common air source heat pump questions.

Do air source heat pumps work in cold weather?
Yes. Modern air source heat pumps extract heat from outside air down to -20°C. Even on the coldest UK winter days, an ASHP will heat your home and hot water reliably. Efficiency drops slightly in extreme cold, but the system compensates automatically.
Do they work with radiators?
Yes. Air source heat pumps work with standard radiators. Because heat pumps run at lower flow temperatures than gas boilers, some radiators may need upsizing to deliver the same heat output. We assess every radiator during the survey and only recommend changes where necessary. Many homes need no radiator changes at all.
How noisy are they?
Modern air source heat pumps operate at around 40-45dB — about the same as a fridge or a quiet conversation. Planning rules require units to be no louder than 42dB at the nearest property boundary. We position units carefully to minimise any impact.
Do I need planning permission?
Usually not. Air source heat pumps fall under permitted development rights in England, so most installations don't need planning permission. There are some conditions — the unit must be a certain distance from boundaries, and listed buildings or conservation areas may have restrictions. We check this during your free survey.
What size do I need?
It depends on your property — the size, insulation levels, number of radiators, and hot water demand. A typical 3-bed semi might need a 7-10kW system. We carry out a detailed heat loss calculation during the survey to determine exactly what your home needs. Getting the sizing right is critical for efficiency and comfort.
