How heat pumps work
A heat pump moves heat from warmer areas to cooler ones. It uses a small amount of energy to transfer heat, instead of creating it from scratch.
Heat pumps use a special fluid called refrigerant. This refrigerant absorbs heat from the outside air or ground and transfers it into the building for heating purposes. During summer, the process can be reversed to cool the building by removing heat from the inside and transferring it outside.
What types of heat pumps are there?
So, what are the different types of heat pumps? There are two main types of heat pumps and each uses a different heat source: air source heat pumps and ground source heat pumps.
Ground source heat pump
Ground source heat pumps (GSHP) extract heat from the ground using a network of underground pipes. These heat pumps are efficient and reliable, even in colder climates, making them a popular choice for home heating. A GSHP tends to be more expensive to install but offers lower operating costs and a steady heat supply.
Air source heat pumps
Air source heat pumps (ASHP) draw heat from the outside air and are suitable for homes or apartments in milder climates. Air sourced heat pumps can be easily installed. Although cost effective, they may not work as well in very cold weather.
How much do heat pumps cost?
With energy prices rising, it is only natural to look for tips on saving electricity at home. The cost of heat pumps varies according to the source and the maintenance of the two types of heat pumps.
The cost of installing a heat pump is typically between £5,000 to £45,000 with ongoing expenses on top of that. Air-to-water heat pumps usually begin at around £5,000, while ground-source heat pumps tend to cost between £13,000 and £35,000, with some reaching up to £45,000. The amount of energy a heat pump consumes will depend on factors such as the insulation of your home and its size.
Benefits of heat pumps
Heat pumps offer several benefits for homeowners looking for an energy-efficient heating solution. Here are some of the key advantages you can expect from heat pumps:
-
Energy efficient
They use less energy, leading to lower bills compared to traditional heating systems. -
Eco-friendly
Using renewable energy sources, heat pumps help reduce carbon emissions and are an environmentally friendly option. -
Versatile
Heat pumps can be used for both heating and cooling, making them a versatile option for UK homes in a variety of climates. -
Grants available
There are grants available, like the Boiler Upgrade Scheme, to help offset the costs of installing an air source heat pump.
Drawbacks of heat pumps
However, when deciding to switch to a heat pump system, be aware of some of their drawbacks too:
-
High upfront cost
The initial cost of installing a heat pump can be substantial, particularly for ground source heat pumps which can cost upwards of £13,000. -
Weather dependency
Air source heat pumps may struggle in extremely cold temperatures. -
Noise
Some heat pumps can be noisy, particularly outdoor units, which may concern homeowners. -
Maintenance
Heat pumps require regular maintenance to function optimally, which can be expensive and time-consuming. -
Limited use
Heat pumps may not be suitable for larger homes or commercial properties, as they may not be able to generate enough heat to meet the demand.
Installing a heat pump
Installing a heat pump in a house can be a big decision to make, and there are many factors to consider before you make the switch.
The type of heat pump impacts installation costs significantly. Ground source heat pumps are usually more expensive due to the need for underground pipes, while air source heat pumps are simpler and cheaper to install.
Whichever pump you choose, it’s best to ensure your home meets the necessary requirements for installation.
What are renewable heat incentives?
If you're looking for ways to reduce your carbon footprint and save money on your energy bills, you may want to consider the Renewable Heat Incentive (RHI). The RHI scheme is a UK government incentive to encourage the use of renewable heating technologies, like heat pumps.
The scheme provides financial incentives to encourage households and businesses to switch from traditional fossil fuel heating systems to renewable heating systems, such as air-source heat pumps or ground-source heat pumps.
To make the most of the RHI, you must install eligible renewable heating systems and register for the scheme. You'll then receive quarterly RHI payments for seven years based on the renewable heat your system produces. To qualify, the system must meet specific technical and environmental standards and be installed by a qualified professional.
Now that you understand heat pumps, their benefits, and their limitations, you can make a well-informed decision about installation. If you found this guide useful, be sure to check out more home tips and guides at AXA home insurance.
