What temperature should underfloor heating be set to?
Floor surface temperature should be 25–29°C for comfort. Flow temperature from the boiler is typically 35–55°C — much lower than radiators, maximising efficiency.
What Temperature Should Underfloor Heating Be Set To?
Underfloor heating works at much lower temperatures than traditional radiators — this is one of its key efficiency advantages.
Recommended Settings
| Setting | Recommended Range | |---------|------------------| | Floor surface temperature | 25–29°C (max 27°C under furniture) | | Flow temperature (wet UFH) | 35–55°C | | Room thermostat setting | 19–22°C (typical comfort) |
Why Lower Flow Temperatures Are Better
- Condensing boilers are most efficient at low return temperatures
- Heat pump compatibility improves dramatically below 45°C
- Lower flow temperature = longer system life
Room-by-Room Considerations
- Bathrooms — can be set slightly higher (22–24°C room temp)
- Bedrooms — cooler settings aid sleep quality (18–20°C)
- Living areas — 20–22°C is standard
- Under furniture — limit floor temp to 27°C to prevent damage
Heatmiser Controls
With a Heatmiser neoHub system, each room is independently controlled and can have its own schedule, optimum start settings and holiday mode.
