If you’ve been looking into energy-efficient ways to heat your home, you’ve probably come across air source heat pumps. With rising energy costs and more homeowners looking for greener heating solutions, heat pumps are becoming increasingly popular across the UK.
But how do they actually work? Are they expensive to run? And are they right for homes here in Lancashire?
In this guide, we’ll answer some of the most common questions homeowners ask before installing an air source heat pump.
How Does an Air Source Heat Pump Work?
An air source heat pump works by taking heat from the outside air and using it to warm your home and hot water.
Even when it feels cold outside, the air still contains heat energy. A heat pump captures that energy and transfers it into your home using a refrigerant system, compressor, and heat exchanger.
In simple terms, it works a bit like a fridge—but in reverse.
Instead of removing heat from inside your home, it pulls heat from outside and uses it to:
- Heat your radiators
- Power underfloor heating
- Provide hot water for your home
Because it moves heat rather than creating it by burning fuel, it can be far more energy efficient than traditional heating systems.
Do Air Source Heat Pumps Work in Winter?
Yes—they’re designed to work all year round, including during UK winters.
Modern air source heat pumps can continue extracting heat even when outside temperatures drop below freezing. This makes them a great option for homes across Lancashire, Preston, and surrounding areas.
The better insulated your home is, the more efficiently your heat pump is likely to perform during colder months.
What Are the Downsides of Having a Heat Pump?
Like any heating system, air source heat pumps aren’t perfect for every property.
Some things to consider include:
Higher Upfront Installation Cost
In some cases, homeowners may qualify for support through the UK Government Boiler Upgrade Scheme, which can help reduce installation costs.
Best Performance in Well-Insulated Homes
Heat pumps work most efficiently in homes with good insulation, modern windows, and reduced heat loss.
Installation Space
You’ll need suitable outdoor space for the external unit.
That said, many homeowners find the long-term energy savings and lower carbon footprint make the investment worthwhile. According to the Energy Saving Trust, air source heat pumps can provide an efficient low-carbon alternative to traditional heating systems.

How Much Does an Air Source Heat Pump Cost?
The cost of installing an air source heat pump can vary depending on:
- Property size
- Existing heating system
- Insulation levels
- Pipework and radiator upgrades
- Hot water cylinder requirements
Every home is different, which is why professional advice is important before choosing the right system.
How Much Does It Cost to Run a Heat Pump?
Running costs depend on:
- Your electricity tariff
- Home insulation
- Temperature settings
- Size of the property
- How often the system runs
Because heat pumps are highly efficient, many homeowners find they offer lower running costs compared with older electric heating systems or inefficient boilers.
What Are Some of the Leading Heat Pump Brands?
There are several trusted manufacturers in the UK market, including:
- Daikin
- Mitsubishi Electric
- Vaillant
- Samsung
- Panasonic
The best system for your home will depend on your property size, heating requirements, and budget.
Are Air Source Heat Pumps Worth It?
For many homeowners, yes.
Air source heat pumps can offer:
- Lower carbon emissions
- Improved energy efficiency
- Reduced reliance on fossil fuels
- Consistent heating throughout the year
- Potential long-term energy savings
They can be especially effective when combined with good insulation and modern heating controls.
