A practical guide to choosing the right system for existing homes in Devon and Cornwall.
Underfloor heating is increasingly popular in renovation projects, but choosing the right system is more complicated than in new builds. The best option depends on your floor construction, how much disruption you can accept, and your budget.
Here’s a clear breakdown of the systems that work well in renovation projects.
Adding underfloor heating can raise floor levels, which may affect doors, skirting boards, and transitions between rooms. Keeping the build-up as low as possible is often a priority.
Some systems require lifting floorboards or removing existing flooring. If you're living in the property during the works, minimising disruption becomes very important.
Many older properties have a mix of solid concrete floors on the ground floor and suspended timber floors upstairs. Each requires a different approach.
Underfloor heating performs best with lower water temperatures. If you're installing it alongside a heat pump, this becomes even more important.
These systems are laid on top of an existing solid floor. They cause relatively little disruption and have a low build-up height.
Used in suspended timber floors where floorboards can be lifted. These systems sit between the joists and are a good option for period properties.
These combine structural support and underfloor heating. Useful when replacing floors during a renovation.
For most renovation projects in Devon and Cornwall, we generally recommend modern overlay systems on solid floors and between joist systems on suspended timber floors.
The right choice depends on your specific situation. Getting advice from someone experienced in both underfloor heating and renovation projects can help you avoid costly mistakes.
