- Testing - Verify heating element continuity and insulation
- Flooring - Install final flooring (tile, vinyl, laminate) over heating
- Thermostat - Install thermostat and temperature sensor
- Electrical - Install dedicated circuit and controls
- Commissioning - Test full system operation
- User Training - Explain operation and thermostat use

Flooring Compatibility
Electric underfloor heating works with:
Best Options:
- Ceramic tile (excellent heat transfer)
- Stone (excellent heat transfer)
- Vinyl/Luxury vinyl (good heat transfer)
- Engineered wood (reasonable heat transfer)
Acceptable Options:
- Laminate (adequate, but some debate)
- Carpet (suitable if low pile, low tog rating)
Avoid:
- Thick carpets (insulates against heat)
- Wooden floorboards (can warp with heat)
- Thick cork or rubber underlays
We advise on flooring selection to ensure compatibility and performance.
Running Costs & Savings
Typical Monthly Running Cost (1,500W system, 3 hours daily):
- 1,500W × 3 hours/day × 30 days = 135 kWh/month
- At £0.25/kWh typical = £33.75/month
Energy Savings Potential:
- Primary heating source: reduced by 10-20% (whole house)
- Supplementary heating: 20-30% savings common
- Zone control: significant savings if some rooms unused
- Smart thermostat integration: additional 10-15% savings
Payback Period:
- Modest bathroom system: 2-4 years (through comfort/water saving)
- Larger whole-house system: 5-10 years through energy savings
- Lifetime cost lower than radiator replacement cycles
Factors Affecting Running Costs:
- Insulation quality of property
- External temperature and climate
- Heating hours and temperature settings
- Usage patterns (occupancy hours)
- Electricity tariff rates

Frequently Asked Questions
QIs underfloor heating energy-efficient?
Yes, it's more efficient than radiators (heats from ground level). Provides 10-20% savings compared to radiator heating through even distribution and zone control.
QCan I install underfloor heating over existing floor?
Usually not practical (would raise floor height significantly). Best during renovation or in new construction.
QDoes underfloor heating work under carpet?
Yes, but requires low-pile, low-tog carpet (tog rating under 2.5). Thick carpets insulate against heat. We recommend tile/vinyl for bathrooms.
QWhat's the maximum safe floor temperature?
Typically 27-35°C (set by thermostat). Temperatures higher than this can damage flooring or cause discomfort.
QCan I use underfloor heating as only heating source?
Yes, but works best as primary heat source in well-insulated homes. Supplementary to central heating more common.
QHow quickly does underfloor heating warm up?
Typically 30-60 minutes to reach set temperature (longer than radiators, but stays warm longer when turned off).
QIs underfloor heating safe?
Yes, completely safe. RCD protection standard. Temperature-limited by thermostat. No exposed elements. Safe around children and pets.
QWhat about the long-term reliability?
Electric heating elements extremely reliable. Expected lifespan 20-30+ years. No moving parts to wear out.
