Wet underfloor heating review

All underfloor heating insulation requirements must comply to the latest building regulations. Normal screed can be used for underfloor heating systems.  No further additives are required. Anhydride screed can be 50 mm only.  It is very important to use a vapour barrier when using liquid screed for wet underfloor heating.

The best floor finish for underfloor heating water systems are tiles or a stone floor as these floor finishes have very low thermal resistance.  Use flexible fixing adhesive to avoid cracks.

Any type of boiler can be used for underfloor heating.  Mixing valves must be used to lower the temperature for the underfloor heating system.

Electric boilers can also be used with water underfloor heating.

For a domestic building the hot water demand is normally about 3 kW.

Underfloor heating water is best operated 24/7 every day of the heating season.  Night set-back is normally used to lower the temperature of the underfloor heating system during the night.  Maximum drop for night set back should not be higher than 6   degree C.

Our underfloor heating system can be fixed if there is a leak.  The underfloor heating pipework for the loop that has been damaged needs to be isolated and the floor surface exposed.  By using our underfloor heating coupler the leak can be fixed.
