Frequently Asked Questions
A heat pump doesn't make heat. It moves it. Using electricity, it pulls heat from the air outside your home and brings it inside.
Because it moves heat rather than generating it, a heat pump produces 3-5 units of heat for every 1 unit of electricity used. That's what makes it so efficient.
Main Types of Heat Pumps
-
Air-Source Heat Pumps (ASHP): The most common option, which extracts thermal energy from ambient outdoor air via an outdoor fan coil.
-
Ground-Source Heat Pumps (GSHP): Uses buried horizontal pipe trenches or deep vertical boreholes filled with a water-glycol mixture to extract stable heat energy from the earth.
-
Water-Source Heat Pumps (WSHP): Extracts thermal energy from nearby water bodies such as rivers or lakes using open or closed fluid loops.
Heat Delivery Methods
-
Air-to-Air Systems: Deliver heat or cooling via indoor fan coils, offering rapid temperature adjustments, air conditioning, and air filtration.
-
Air-to-Water Systems: Circulate heated water through radiators or underfloor heating, providing steady, consistent radiant heat.
Common System Configurations
-
Monoblock Systems: Houses all refrigerant components within a single outdoor unit, simplifying installation and eliminating the need for custom refrigerant lines inside the property.
-
Split Systems: Separates components between an outdoor unit and an indoor unit connected via refrigerant piping, providing setup flexibility for larger properties.
Not when engineered and set up correctly for your property. Because heat pumps operate at high efficiency, running costs can be significantly lower than a traditional gas or oil boiler. Systems designed to certified standards (such as Heat Geek guidelines) operate up to 50% more efficiently than the UK national average, helping keep your monthly energy bills consistently low.
Most UK homes are suitable for a heat pump. The key isn't the age or size of your home, it's how the system is designed around it. A well-designed installation will outperform a boiler in almost any home.
The total cost of a heat pump installation typically ranges between £12,000 and £18,000, depending on your property's size and heating requirements. However, with the UK Government's £7,500 Boiler Upgrade Scheme (BUS) grant applied, the net out-of-pocket cost for many homeowners is comparable to replacing an old boiler system.
In many cases, yes, especially when paired with specialised green energy tariffs, underfloor heating, or low-temperature radiators. When factoring in long-term gas price inflation, overall running costs depend heavily on system efficiency and your tariff structure, so it is worth looking closely at your options.You can use the Heat Geek Running Costs Calculator to get a clear idea of what your running costs could look like.
If you're thinking about switching to a heat pump, there's never been a better time. On top of the £7,500 Boiler Upgrade Scheme grant, many UK banks are now offering their mortgage customers exclusive cashback deals to help cover the cost of switching to greener home heating. You can view the latest bank cashback offers in this Heat Geek savings guide.
