Choosing between electric and water-based underfloor heating depends on your home build stage, room size, and energy source. Remote controlled thermostats with WiFi heating control make both systems smarter, letting you adjust temperatures from your phone anywhere. Repenic thermostat models match each type perfectly for UK homes in early construction phases.

Comparing Electric and Water Heating Methods
Electric underfloor heating uses mats or cables embedded in the floor to generate heat directly from electricity. This system suits bathrooms, kitchens, or small rooms up to 20 square meters, offering quick warm-up in 15 to 30 minutes. Water-based underfloor heating, or wet systems, circulates heated water through pipes connected to your boiler, ideal for whole-house setups over 50 square meters.
Water systems run at lower temperatures around 35 to 45 degrees Celsius, pairing well with heat pumps for efficiency. Electric options hit 25 to 31 degrees but spike running costs since electricity costs more than gas per kWh. For new builds, water underfloor heating integrates seamlessly during screed pouring, while electric fits retrofits with minimal disruption.
Both deliver even heat from floor level, reducing cold spots and improving air quality over radiators. Remote controlled thermostats enhance user control, with WiFi heating control apps scheduling boosts for morning routines or evenings.
Load Requirements for Each System
Electric underfloor heating demands 100 to 200 watts per square meter, depending on insulation and room use. Bathrooms often need 150W/m² for tiled floors, while conservatories hit 200W/m² to combat heat loss. Zoning multiple mats keeps loads balanced, avoiding circuit overloads in older UK wiring.
Water-based systems require lower electrical loads for pumps, typically 50 to 100 watts total, as the boiler handles main heating. Flow rates of 1 to 2 liters per minute per loop ensure even distribution without high power draws. OpenTherm protocols optimize boiler modulation, cutting gas use by 10 to 15 percent.
Load calculations matter early in builds—electric pulls direct from mains, risking 13-amp fuses, while water ties into existing central heating. Remote controlled thermostat compatibility checks voltage and relay ratings to prevent faults.
Repenic Thermostat Models for Electric Heating
Repenic's RE-WiFi-E model excels for electric underfloor heating with remote controlled thermostat features. This WiFi heating control unit handles 16-amp loads, supporting mats up to 150W/m² across zoned rooms. App-based geofencing activates heat as you arrive home, with open window detection pausing output.
Floor sensors integrate precisely, maintaining 21-degree setpoints without overshoot. UK plug-and-play design fits standard back boxes, ideal for London renovations or Manchester new builds. Energy reports track kWh usage, helping cut bills by scheduling off-peak boosts.
Pair it with Repenic RE-Dual for hybrid rooms blending electric mats and radiators. Voice control via Alexa or Google Home adds hands-free WiFi heating control convenience.
Repenic Controllers for Water-Based Systems
For water underfloor heating, Repenic RE-OpenTherm suits boilers with remote controlled thermostat precision. This model modulates water flow via OpenTherm, reducing pump runtime by 20 percent compared to on-off controls. WiFi heating control lets you tweak curves remotely for underfloor plus towel rails.
It supports multiple zones across Bristol homes or Edinburgh extensions, with load relays up to 10 amps for actuators. Adaptive algorithms learn your habits, pre-heating slabs overnight for even warmth by morning.
The RE-Hydro-Pro variant adds pressure monitoring for long pipe runs in Birmingham projects. Both offer seven-day programming through intuitive apps, ensuring water underfloor heating efficiency year-round.
