Air Source Heat Pumps
(ASHPs)
A cleaner, smarter way to heat your home.
What Is an Air Source Heat Pump?
An air source heat pump (ASHP) – also known as an air-to-water heat pump – extracts renewable heat from the outdoor air and transfers it into your home. This heat is then used to:
-
Warm your home through radiators or underfloor heating
-
Heat a hot water cylinder for your taps, showers, and baths
ASHPs work efficiently all year round, even at low outdoor temperatures, providing a reliable and sustainable heating solution.
Benefits of installing an Air Source Heat Pump
Renewable Heating Using Natural Thermal Energy
Modern heat pumps operate quietly, have a sleek, contemporary design, and are suitable for both new builds and existing homes.
Air source heat pumps collect thermal energy from the air and amplify it using electricity. For every unit of electricity used, a heat pump can typically produce 3–4 units of heat, making them significantly more efficient than traditional oil or gas boilers.
Why they’re efficient:
-
They extract renewable heat from outdoor air
-
They use a finely finned evaporator coil to maximise energy absorption
-
They significantly reduce reliance on fossil fuels
This means lower running costs, reduced carbon emissions, and greater energy security for your home or business.
One Single Energy Bill
When you switch to a heat pump, all your home’s energy use – lighting, appliances, heating, and hot water – is powered by one electricity bill.
This makes budgeting easier and supports long-term savings, especially when paired with:
-
Low-rate electric tariffs
-
Solar PV panels
-
Smart energy management systems
Heat pumps also help reduce your carbon footprint by replacing oil, LPG, or solid fuel heating systems with a clean alternative.
Domestic Installations Tailored to You
We provide air source heat pump installation for both residential and commercial properties.
For homes, our priority is maximising efficiency and lowering ongoing costs. Typical domestic installations use an 8–10 kW system, depending on your property size, insulation levels, and heat demand.
Before installation, our team will assess:
-
Your heating and hot water needs
-
Your current system
-
Your home’s insulation levels
-
Your eligibility for grants or incentives (if applicable)
This ensures your heat pump performs at maximum efficiency from day one.
