Underfloor Heating Systems for Residential Retrofit Projects

Retrofit projects require carefully selected underfloor heating systems that work within existing floor structures, height constraints, and lived-in environments.

Overlay (Low-Profile) System

Best for: Renovations, occupied homes, minimal floor height build-up
A low-profile retrofit system installed over existing subfloors using pre-routed insulation panels or trays. Heating pipes sit close to the finished floor level, allowing for efficient heat output with minimal disruption. Ideal for full-house retrofits, ground floors, and upstairs renovations where buildup height is limited.

Between-Joists System (Suspended Floors)

Best for: Timber joist floors and upper levels
Designed for suspended timber floors, this system fits heating pipes between joists and uses a dry or thin screed build-up to bring the floor to finished level. It delivers effective heat distribution without excessive floor height increase and is well suited to first floors and traditional timber constructions.

Screeded Tacker (Staple) System

Best for: Existing concrete slabs and solid ground floors
Where sufficient floor depth is available, heating pipes are stapled directly to insulation and encapsulated in flowing screed. This approach provides excellent thermal mass and even heat distribution, making it a strong option for major renovations where floors are being lifted or rebuilt.

Electric Underfloor Heating System

Best for: Bathrooms, small areas, heritage or limited-access spaces
A compact electric solution used where water-based systems aren’t practical. Typically installed beneath tiled floors in bathrooms, kitchens, or single rooms, it offers fast warm-up times with minimal floor build-up. Often specified as a supplementary system rather than whole-house heating.
