FAQ
Can a heat pump provide all the heating, including showers and baths, without a backup boiler?
Yes! A well-designed, well-installed heat pump will provide all of your heating and hot water needs.
Is there funding available for heat pump installation?
Yes, there funding options available through the Home Energy Scotland (HES) Grant and Loan scheme. Visit https://www.homeenergyscotland.org/home-energy-scotland-grant-loan to find out more.
Can heat pumps effectively work with both radiators and underfloor heating, and should I replace existing radiators with larger ones or switch to underfloor heating?
Yes, heat pumps are compatible with both radiators and underfloor heating systems. When using radiators, it may be necessary to have slightly larger ones to ensure sufficient heat output at the lower flow temperatures required for optimal heat pump efficiency. While heat pumps can work with existing radiators, the decision to replace them with larger ones or switch to underfloor heating depends on the unique requirements of your home and the age and size of your radiators. Our experienced technical consultants will assess your situation and provide guidance on the most suitable installation for your project.
How much indoor space is needed for a heat pump system installation?
Heat pumps require more space compared to wall-hung boilers. It’s a good idea to plan a dedicated area for the equipment. Utility rooms, garages, basements, and detached outbuildings can serve as suitable plant rooms. A typical ground source system requires an area approximately 2m deep by 2m-2.5m wide. Air source systems require less space, usually about 1.5m deep by 1.5m wide, plus the outdoor fan unit.
Do I need planning permission to install a heat pump?
In most cases, the installation of a ground source heat pump is considered permitted development and does not require planning permission. A single air source heat pump is also usually considered permitted development, subject to certain criteria being met. However, if you live in a listed building or a conservation area, it’s best to check with your local council for any specific requirements.
How much does a heat pump system cost to install?
The cost of installing an air source heat pump usually ranges between £9,000 and £15,000, depending on factors such as the size, power, hot water storage requirements, and internet controllability. Ground source systems can cost from £15,000 to over £30,000, depending on the heat pump size, hot water cylinder, and the chosen loop or borehole system.
Are air source heat pumps noisy?
Modern air source heat pumps are designed to operate quietly and should not cause disturbances if installed properly. Planning regulations typically require the noise level at the nearest assessment point (usually your neighbour’s window) to be 42db or less, like the background noise in a library.
