Your CPD: Questions – how to assess UFH systems

​Underfloor heating (UFH) systems have a range of heat outputs, which are dependant on several key variables

1. Name three variables that determine the heat output of a UFH system.

2. Which British Standard is used to calculate the heat output of a UFH system?

3. How can an installer determine the pipe centres in an existing UFH system?

4. Name two of the UFH system types covered in the CIPHE low temperature guide.

5. In a screed UFH system, what would a typical floor heat output be (in W/m²) if the MWT was 42°C and the UFH pipe distance was 250mm?

6. In a UFH system in aluminium plates (screed board intermediate layer), what would a typical floor heat output be (in W/m²) if the MWT was 45°C and the pipe distance was 250mm?
