Underfloor Heating Advice & Installation Support

Underfloor heating (UFH) is comfortable, frees up wall space and works particularly well with heat pumps and well-insulated floors — but the right system depends on the floor build-up and how the room is used. EvoHome Improvements helps homeowners across Hampshire and the South think through wet (hydronic) vs electric UFH, retrofit vs new build, insulation underneath, screed depth and warm-up time, floor finish suitability (tile, engineered wood, LVT, carpet), zoning and controls, and how UFH integrates with existing or proposed heating systems.

EvoHome Improvements advises and coordinates — independent vetted heating and electrical specialists carry out the physical installation, commissioning and certification. We do not quote fixed prices, exact timescales, guaranteed running costs or guaranteed warm-up performance without a proper survey. Underfloor heating provides the most comfortable and efficient way to heat a home, distributing warmth evenly across the entire floor surface at lower temperatures than radiators.

Combined with a heat pump, it represents the gold standard for modern home heating.\n\n## Electric vs Wet Systems\n\nElectric systems use heating mats or cables beneath the floor, ideal for single rooms or retrofits. Wet systems circulate warm water through pipes embedded in or beneath the floor, offering lower running costs for whole-house installations.

Wet systems pair perfectly with heat pumps due to their low flow temperature requirements (35–45°C).\n\n## Floor Build-Up\n\nThe total floor build-up depends on the system type. Electric mats add just 3–5mm, making them ideal for retrofits. Standard wet systems in screed add 65–75mm. Low-profile wet systems designed for retrofit add 15–25mm, avoiding the need to raise door thresholds.

\n\n## Compatibility with Floor Coverings\n\nTile, stone and polished concrete are ideal — they conduct heat efficiently and respond quickly. Engineered wood performs well with proper acclimatisation. Thick carpet with heavy underlay should be avoided as it insulates against the heat, reducing efficiency by up to 40%.\n\n## Hampshire Considerations\n\nHampshire's moderate climate makes underfloor heating particularly efficient.

The lower operating temperatures mean heat pumps achieve higher coefficients of performance, and the steady, even warmth suits the region's variable weather patterns.
