Could a heat pump save you money?
The amount of money you could save from switching to a heat pump will depend on several factors. Keep in mind the upfront cost too. These factors include:
-
01
How well your house is insulated. Preventing the heat from escaping through your walls, roof and floors will make your home more energy efficient. Heat pumps deliver medium heat continuously. Therefore, your property will need to be well insulated to fully benefit from the heat pump's higher efficiency.
-
02
The climate where you live. Heat pumps can extract heat in temperatures as low as -15C. However, the amount of electricity required could increase in lower temperatures as the heat pump would need to work harder.
-
03
Your current heating system. Most heat pumps use radiators and underfloor heating. To avoid inefficiencies, you might need to adjust your heating system when installing a heat pump. For example, smaller radiators may make the heat pump work harder than larger radiators.
-
04
The type of heat pump. Being highly efficient, heat pumps use less energy than they produce. However, different types of heat pump are suitable for different types of homes and the results will vary. Depending on the size of the property, the surroundings and the amount of heat required.
Air-to-water heat pump
An air-to-water heat pump transfers heat from the outside air to water. It can then be used to heat your home through radiators or underfloor heating. An air-to-water heat pump can be used to heat your water. This is the most common heat pump in the UK.
The costs are between £7,000 and £13,000.

Ground-to-water heat pump
A ground-to-water heat pump (or geothermal heat pump) extracts heat from the ground into a fluid, which then heats up your radiators or underfloor heating. This heat pump can also heat your water.
The costs usually range between £14,000 and £19,000. However, the actual cost will depend on the type of your property and the required groundwork.

Air-to-air heat pump
An air-to-air heat pump is suitable for smaller properties. It uses a fan system for heating and cooling your home. However, air-to-air heat pumps don't heat water.
The advantages of air-to-air heat pumps are the easy installation and lower costs, which could be between £1,600 and £3,100.

The estimated costs of the different types of heat pump stated in this article were taken from the Energy Saving Trust.
Costs and support
Heat pumps can cost more than a boiler, but have lower operating costs.
To support the government's ambition to install only low carbon heating systems from 2025, financial support is available. This means you could be eligible for financial support to help you switch to a heat pump.

Energy efficiency
Heat pumps are highly efficient as they can generate between 3-4 times more energy than they consume.
The exact energy savings you might get will depend on your home's current heating system, which may also be efficient, and insulation.

Cleaner energy
Heat pumps can be powered by solar panels or other sources of renewable energy, which makes them a better option for the planet. Rather than burning fuel, heat pumps use electricity for power and produce more energy than they consume.
