  • Combining Heat Pumps And Solar Panel Heating
Last updated: 22 March 2024

Combining Air Source Heat Pumps and Solar Panels: UK Guide

Combining Air Source Heat Pumps and Solar Panels
  • Solar panels and heat pumps can be combined to produce cheaper, more sustainable, and energy-independent heating and cooling.
  • A 3kW to 5kW solar system is sufficient to power the average UK home with a heat pump.
  • The cost of an air source heat pump and solar panels can be between £9,500 to £20,000 on average.
  • Solar panels and heat pumps combined can save between £1,250 to £2,100 annually.

As a heating and cooling system, heat pumps are already very efficient. But did you know you can go a step further in sustainable and renewable operations by combining air source heat pumps and solar panels to produce your own energy?

Since both solar panels and heat pumps are such an expensive investment, finding a trustworthy installer is crucial. A reliable installer can keep your costs low and ensure that the job is done right. The only problem is that finding one can be a hassle that takes days of research and calling up companies. If you don’t have time for that, our service can offer a far better solution.

By filling in a simple, 30-second form, we’ll provide you with the best prices from the best heat pump installers in your area.

Can solar panels be used to power a heat pump?

ASHP Solar Panels

Solar panels work very well with an air source heat pump system. Air source heat pumps are reliant on electricity and solar panels can diminish their operational costs while also making them more or less 100% sustainable. Under most circumstances, ASHPs require far less energy than a standard boiler, which means that they will put less load on solar panels and can even work at nighttime when paired with solar batteries.

Despite how little energy they can use, one of the only issues with heat pumps is that they can still be reliant on the energy grid, which diminishes their capabilities as a renewable energy source. With a solar-powered heat pump, that won’t be an issue.

There are certain features air to air heat pump systems lack that other versions of ASHPs can manage. Air to water heat pump can also be connected to underfloor heating and the radiators in your home. Although the former will require additional installation and underfloor heating costs.

How many solar panels do I need to power an air source heat pump?

The number of panels you need to power both your home and a heat pump can vary based on the size of your home and how much power your heat pump will use. The average home has 2 to 3 bedrooms and will need a 5kW heat pump and 4kW solar panels.

How many solar panels to power your house + heat pump?

2 to 3-bedroom house4kW panel system5kW8
3 to 4-bedroom house5kW panel system10kW10
4 to 5-bedroom house6kW panel system16kW13

Heat pump size doesn’t refer to the physical dimensions of the device but rather how high a heat output (measured in kW) it can manage. A 5kW heat pump can adequately heat up a space of up to 35m2 to 45 m2, making it a great option for smaller homes. Larger spaces may require a 10kW system or higher which will mean a higher air source heat pump price.

What is the cost of an air source heat pump and solar panels?

cost of an air source heat pump and solar panels

The cost of an air source heat pump and solar panels can be roughly between £7,000 to £35,000. This depends on the size of the solar panels and the power of the heat pump along with whether you can apply for the Boiler Upgrade Scheme. Solar panel and heat pump costs can also be mitigated by other heating and solar panel grants such as the 0% VAT policy and the ECO4 scheme.

16 kW£15,000£12,000 – £13,000£27,000 – £28,000£20,000 – £22,000

Solar panel cost and installation can be expensive but it’s also important to note that they illustrate the prices for powering your whole home with solar. You can, instead, also buy a modest set of panels to offset some of the costs rather than the whole home’s electricity. Solar panels for heat pump systems don’t need to always be as large as possible depending on your needs.

One way to help mitigate problems related to the cost of solar-powered heat pumps is to find a reliable installer. While this usually takes days of in-depth research and calling up companies, our service can streamline the process and reduce it down to filling out one 30-second form.

Is an air source heat pump with solar panels suitable for my home?

Is an air source heat pump with solar panels suitable for my home

The number of solar panels you can put on your home depends on your budget and how much roof space you have. Aside from that, heat pumps are less energy-intensive than other types of home electrical heating and cooling systems (unless they are badly insulated). This makes them less intensive for solar panels than electric boilers.

In terms of roof materials, there are quite a few good ones. Asphalt, or composite roofing, is potentially the best for installing solar. Its durability makes it well-suited for holding up an array. Metal standing seam roofs are also great and, due to the ease of installation they provide, can save money on costs.

Roofs should face south and, ideally, be tilted 30° to 50° for sunlight capture. Flat roofs can also work but then you’ll need to install brackets that hold your solar panels to an angle and a direction, which could cost more.

For heat pumps, you will ideally need an insulated home to feel the full effect of the installation. Air source heat pumps can be suitable for a wide range of homes compared to other types of heat pumps. Both water source and ground source heat pumps require more elaborate installations, requiring water bodies and free land respectively. This is also why water and ground source heat pump prices are much higher, often ten times.

Should you get an air source heat pump combined with solar panels?

While getting both solar panels and air source heat pumps can be expensive, the advantages can be great. The savings can be as high as £2,100 per year and you can be certain that you’re energy-independent. Assuming the cost of your setup is £14,000 (the lowest cost model), the savings over time can lead you to break even in between 7 to 8 years.

One of the best ways to reduce the cost of your solar panels and heat pumps is to find the right installer. Getting a reliable one means you are getting the best prices and the best service. The search for a good installer can be complicated as it requires days of deliberating over prices and calling up companies. Luckily, we provide a far more convenient and quicker way.
