Heat Outputs

When designing conventional heating systems it is necessary to know the required heat output to determine the size of the heat emitter. When designing an underfloor heating system, the heat emitter is the floor area and is fixed.

The heat output achieved is a direct relationship between the difference in floor surface temperature and room air temperature. The floor construction, floor covering material, pipe size, pipe spacing (or pipe centres), and the temperature of water circulating through the UFH pipes are major factors that determine the floor surface temperature.
