There are many ways to control an underfloor heating system.
First of all, almost any boiler can be used for underfloor heating. The most energy efficient system to use with underfloor heating is a condensing boiler. Note, if the underfloor heating system is going to be used with a combination boiler, always check with the boiler manufacturer that the flow can be fitted with a secondary pump. Our system also works very well with heat pumps.
Underfloor heating is self regulating if the building is properly insulated. Heat output is dependent on the temperature difference between the floor surface and the room temperature.
For underfloor heating, the temperature difference between the floor surface and air temperature is very small; even a slight change in room temperature can significantly alter the temperature difference and the underfloor heating compensates accordingly.
A practical example would be a dining room. First the dining room is completely empty and then when dinner is served, there are many people in the room giving out heat. The underfloor heating will automatically reduce the heat output and the warm water will simply heat another part of the building.
