Every level runs wet underfloor heating rather than radiators. The practical difference is not warmth — it is that there is no furniture you cannot place, and no cold patch two metres from the wall.

The system is zoned per room with individual thermostats, so bedrooms can sit three degrees cooler than living space without anyone arguing about it.

Running costs

Underfloor runs at a lower flow temperature than radiators, which is why it pairs efficiently with the heat pump. Last winter the whole house averaged well under what a comparable radiator system would draw.

Control

Zones are scheduled from an app, with a physical dial in each room for anyone who would rather not use one.
