What is an air source Heat Pump?
-
A heat pump takes energy from the outside air and uses it to heat your home and hot water.
-
Works in all seasons (even cold weather!)
-
Uses electricity but produces much more heat in return
-
A greener, more efficient alternative to gas or oil
How Do They Work?
-
The pump absorbs heat from the air into a fluid
-
A compressor increases the temperature
-
That heat is transferred to your radiators, underfloor heating and hot water
👉 Most systems create 75% of heat from outside air and only need 25% electricity.
Where Will It Be Fitted?
-
The Outdoor unit: a fan unit fitted to the side of your property (wall or floor mounted)
-
The Indoor cylinder: stores your hot water and connects to your heating system
In most homes, a simple monobloc system is fine. If space is tricky, a split system can be installed further away.
What Does It Cost?
-
Not as much as you think – and often less than sticking with fossil fuels.
-
More heat produced than electricity used (this is called the Coefficient of Performance, or CoP)
-
Example: A system with a CoP of 4 gives you 4 units of heat for every 1 unit of electricity used
-
That means lower running costs and better energy efficiency

What is a Ground Source Heat Pump?
-
Ground Source Heat Pumps use natural heat stored in the ground to provide heating and hot water for your home.
-
Reliable, renewable and efficient
-
Works year-round in all weather
-
A smart way to cut your bills and carbon footprint
How Do They Work?
-
A mixture of water and anti-freeze circulates through underground pipes (ground loop)
-
The ground’s natural heat is absorbed and passed into the system
-
A compressor boosts the temperature
-
That heat is used for radiators, underfloor heating and hot water
👉 For every 1kW of electricity used, a GSHP can produce around 4kW of heat – that’s 400% efficiency.
Installation & Lifespan
-
Timeframe: Around a week indoors, with external groundworks depending on design
-
Lifespan: Ground loop lasts 50-100 years, heat pump unit around 20-25 years
-
Once fitted, the system requires very little maintenance
Benefits at a Glance

What Will Be Installed?
-
Outdoor ground collectors: buried underground in trenches or boreholes
-
Indoor unit & cylinder: provides heating and hot water
-
Usually includes upgraded radiators, valves and pipework for maximum efficiency
-
Full compliance with MCS, RECC and building regulations is built into the design
Cost & Incentives
-
Installation costs vary, but are often less than you might think
-
Eligible for the Government’s £7,500 Boiler Upgrade Scheme grant
-
Long-term savings on fuel bills compared to oil, LPG or gas
