Why is the design temperature of an UFH system not being met?

If the design temperature of an underfloor heating system is not being achieve, you should check the following:

• Check all control valves are correctly installed in their correct orientation and that any remote sensors are installed and located in a suitable position.
• Check the temperature settings are as per design and adjust as necessary, depending on the water temperature control system used.
• Check the primary water temperature is not too low. This needs to be at least 10 degrees in excess of the UFH system water temperature
