A realistic example of combining these systems in a reasonably well-insulated home in Devon or Cornwall.
Property Type
4-bed Detached (reasonably well insulated)
System
Air Source Heat Pump + Underfloor Heating
Previous Heating
Oil Boiler + Radiators
Key Factor
Insulation level affects performance and running costs
During a ground floor renovation, many homeowners consider replacing older oil or gas systems with a heat pump and underfloor heating for better comfort and lower carbon emissions.
In this type of example, the property is typically reasonably well insulated, which makes a heat pump a more practical and efficient option.
When insulation levels are good, we often recommend pairing an air source heat pump with underfloor heating. This combination generally delivers even heat distribution and better efficiency. The Boiler Upgrade Scheme grant can also significantly reduce the net cost in eligible cases.
Homeowners often report more even and comfortable heating across the floor compared to traditional radiators.
When the property is reasonably well insulated, running costs are often competitive with previous systems, especially when replacing oil or LPG.
"The house feels much more comfortable now. The even heat from the floor is a noticeable improvement, though results depend heavily on how well the home is insulated."
When a property is reasonably well insulated, combining an air source heat pump with underfloor heating can deliver good comfort and efficiency. The Boiler Upgrade Scheme grant also helps reduce the overall investment in many cases. Results are generally better when insulation has already been addressed or is upgraded at the same time.
