Do I Always Need to Replace my Radiators for a Heat Pump?
No. Many existing radiators can work with a heat pump, but it depends on their size, condition, and how your current heating system is set up. At Thermal Earth, we carry out a full assessment and will advise on the best solution for you and your home.
Why Might Radiators Need to be Changed and How Will I Know?
Heat pumps typically run at lower water temperatures than traditional gas or oil boilers. To provide the same level of heat at lower temperatures, radiators often need a larger surface area. Smaller radiators may not emit enough heat. Thermal Earth will carry out a heat loss calculation and will determine which radiators need upgrading - if any.
What Happens if my Radiators are Too Small?
Possible solutions include:
Replacing some radiators with larger models
Adding extra radiators in certain rooms
Installing low-temperature or fan-assisted radiators
Often, only selected radiators need upgrading - not all of them!
Can I Avoid Changing Radiators by Improving Insulation?
Yes. Upgrading insulation in walls, roofs, floors, and windows reduces heat loss, which could allow existing radiators to perform adequately with a heat pump. Thermal Earth will work with you to look at all possible options.
Is Underfloor Heating Required for a Heat Pump?
No. Underfloor heating works very well with heat pumps because it operates at low temperatures, but a radiator system can also be effective when properly designed.
At Thermal Earth, we have installed hundreds of heat pimps - both with and without underfloor heating. Our experienced heat loss assessors will work with you to design the best performing solution tailored to your home.
Will Changing Radiators Increase Installation Costs?
It can increase upfront costs, but not all systems require radiator replacement. A survey will identify what is necessary before installation.
The Boiler Upgrade Scheme (BUS) will help reduce the cost of installation by £7,500
