Efficient Renewable Heating
Understanding Heat Pumps
Discover how heat pumps work, how they can improve energy efficiency and what to consider before choosing a renewable heating system for your home or business.
Heat Pumps
How Do Heat Pumps Work?
Heat pumps transfer heat from the air or ground into your property, providing an efficient way to heat indoor spaces and, where suitable, hot water.
How it works
A heat pump extracts available heat from the air or ground and transfers it into your property through a controlled refrigeration cycle.
Air-to-Water and Air-to-Air
Air-to-water systems can work with radiators, underfloor heating and hot water. Air-to-air systems distribute warm air directly into rooms.
Insulation Matters
Good insulation helps your property retain heat, improve comfort and make better use of a heat pump system.
Works Well with Solar PV
Solar PV can help provide electricity for a heat pump during daylight hours, supporting a more efficient renewable energy system.
1. High Efficiency
Modern heat pumps are incredibly efficient, delivering between 3 and 6 units of heat energy for every single unit of electricity consumed.
2. Lower Running Costs
Because they use less energy to produce heat, heat pumps typically have much lower running costs compared to traditional fossil fuel boilers.
3. Year-Round Comfort
Many modern heat pump systems can reverse their operation, providing cooling in summer as well as heating in winter for year-round comfort.
4. Low Carbon & Future-Proof
Heat pumps use renewable energy from the air or ground, making them a low-carbon heating solution that supports sustainability and future regulations.
5. Boost to BER / Home Energy Rating
Installing a heat pump can significantly improve your home's BER by increasing overall energy efficiency and reducing emissions.
