Our Top List of Frequently Asked Questions
We regularly get asked lots of different and interesting questions about heat pumps including how they work, what installation costs, how much money they can save. Plumbing questions can be more focussed on how quickly repairs can be made, what servicing and repairs cost and how easy is it to replace radiators or to work on central heating pipes. Some frequently asked questions cover specific topics like these while others are more general and relate to differences between heat pumps and gas boilers for central heating or why water pipes are usually copper.

You can filter our lists by the type of service or products each question related to or simply scroll through our FAQ list.

Right now, the main support available is the Boiler Upgrade Scheme (BUS). This provides £7,500 towards the cost of installing a heat pump.
The grant is taken off the price before you pay anything, and we handle the application process on your behalf. It’s designed to make switching to renewable heating much more affordable for homeowners.
There may also be local or additional schemes depending on your area, which we can advise on during a survey.

Other factors to consider include:
Warranty coverage: Longer warranties provide extra peace of mind and can save money on future repairs.
Efficiency: Modern, energy efficient boilers may cost a little more initially but reduce running costs over time.
Installation quality: A professional, certified installation ensures your boiler performs safely and efficiently, preventing costly issues later.
We help you find the right boiler and installation plan to suit your budget while ensuring reliability and peace of mind.
Heat pumps are an energy efficient way to heat your home, but whether they’re suitable depends on your property and heating needs. Factors we consider include:
- Property size and insulation – well-insulated homes get the most benefit.
- Existing heating system – heat pumps can replace or work alongside certain systems.
- Hot water and heating demand, some properties need higher output systems.
Outdoor space – ground source heat pumps require space for underground loops, while air source heat pumps need a suitable external unit location.
At The Thermal Heat Company, we assess your property, explain your options, and help you choose the right heat pump system. We also guide you through the Boiler Upgrade Scheme (BUS) grant process to help make your project more affordable.
A full heat pump installation including the unit, hot-water cylinder (if needed), system upgrades, and professional installation typically costs around £20,000 for an average home.
However, with the £7,500 Boiler Upgrade Scheme (BUS) grant, this cost can be significantly reduced.
Most homeowners see their final cost brought down to around £12,500, depending on the property and any additional work required (such as radiator upgrades, electrical work, or changes to pipework).
Every home is different, so we always carry out a full heat loss survey and provide a detailed quote to show exactly what the grant covers and what your final contribution would be.
A heat pump works by taking the natural heat that’s already in the air or ground and turning it into usable heating for your home. Even on colder days, there’s still enough energy outside for the system to extract, upgrade and circulate through your radiators, underfloor heating, and hot-water cylinder.
Because heat pumps move heat rather than burn fuel, they run far more efficiently than traditional boilers, giving you reliable, low carbon heating all year round.
