What’s the best type of heat pump?

The best type of heat pump depends on your property and budget. The two main types of heat pump – air source and ground source – offer efficient, eco-friendly heating. But, for most homes, air source heat pumps offer the best balance of performance, price, and ease of installation.

Air source heat pumps (ASHPs)

Air source heat pumps are the most popular choice for UK homes and businesses. They’re easier to install, more affordable, and ideal for most property types.

Ground source heat pumps (GSHPs)

These use underground pipes to extract heat from the earth. They’re more efficient but come with higher upfront costs and require outdoor space for trenching or boreholes.

What’s involved in a heat pump installation?

Installing a heat pump involves five main steps, all carried out by a qualified heat pump installer. Air source heat pump installations typically take 3–5 days with minimal disruption, while ground source systems take longer and are more complex due to groundworks.

1. Home survey

An expert assesses your property’s size, insulation, heating needs, and suitability for air or ground source systems.

2. System design

Your installer recommends the best heat pump type, size, and configuration based on your property.

3. Installation

Air source heat pumps involve fitting an outdoor unit, a hot water cylinder, heating controls, and radiator upgrades. Ground source systems need underground pipes installed, which takes more time and space.

4. Commissioning

The system is fully tested by your heat pump installer before being handed over with clear usage instructions.

5. Aftercare

Many installers offer servicing plans or performance monitoring for long-term peace of mind.

Heat Pump Installation Process

How do heat pump installations work?

Heat pump installations work by capturing heat from the outside environment and transferring it indoors to heat your home and water.

Air source heat pumps absorb heat from the air, while ground source heat pumps extract it from the ground. The system uses a compressor and refrigerant to boost the temperature, then distributes the heat through radiators, underfloor heating, or a hot water tank. Heat pumps run on electricity but are highly efficient, often producing three to four times more energy than they consume.

“I had Alex & Simon at my house. Hands down, they are the best workmen ever, by miles.”

They arrive on time, are polite, super clean & tidy in their work & cleaning up afterwards.

Spectacularly good work was carried out by them both.

They clearly take pride in the quality of work they do & their cleanliness in people’s home, which is sadly lacking for most tradespeople today who just don’t care how shoddy their work is or have no respect for people’s property.”

Heat pump installation FAQs

Have questions about heat pump installations? We’ve answered some of the most common ones here.

Is a heat pump worth the investment?

Yes, a heat pump is worth the investment for most UK homes and businesses. It offers lower running costs, high energy efficiency, and long-term savings compared to traditional heating systems. Heat pumps also reduce carbon emissions and may qualify for government grants, making them both cost-effective and environmentally friendly.

How much does a heat pump installation cost?

A typical air source heat pump installation costs between £10,000 and £15,000, depending on your property size, energy needs, and system complexity. However, you may be eligible for funding through the Boiler Upgrade Scheme, which can reduce the upfront cost by £7,500.

Do heat pumps work efficiently in winter?

Yes, heat pumps are designed to work efficiently in winter, even in temperatures as low as -15°C. Modern air source heat pumps absorb heat from the air and compress it to a usable temperature, delivering consistent heating all year round.

Is a heat pump more efficient than central heating?

Heat pumps can be more efficient than some traditional central heating systems, like gas boilers. This is because they use less energy to operate and tend to have lower running costs, though this does depend on your property.

Which homes are not suitable for heat pumps?

Homes with very poor insulation or limited outdoor space may not be ideal for heat pump installation. However, most properties can be made suitable with basic insulation upgrades and the right system design by a qualified installer.

What’s the process for installing a heat pump?

Heat pump installation involves a home survey, system design, professional fitting, and final commissioning. For air source heat pumps, the process usually takes 2–4 days and involves installing an outdoor unit and internal components such as a hot water cylinder and heating controls.

Are heat pumps noisy?

Not at all. While the outdoor unit might make a soft hum, it’s not something that would disturb you. In fact, most people say they’re more likely to notice the noise of traffic outside their home than a heat pump. Modern systems are designed with noise reduction in mind, making them perfect for homes in quieter areas.

How often do heat pumps need maintenance?

Heat pumps need annual maintenance to keep their performance and efficiency in check. This typically includes looking at refrigerant levels, filters, and electrical components. Regular servicing helps extend the lifespan of your system and keeps it running smoothly.
