It is true that a radiator system will respond faster than a water underfloor heating system to temperature alterations but, as it stays on 24/7 with temperature setback, this is no longer an issue. It is cheaper and more efficient to run the system 24/7 than it is to heat it up once the screed has cooled down. Reducing the room temperature at night to 16°c will work well with any of our systems.

Normally, a boiler produces a water temperature of up to 82°c, this is fine for a radiator system, but too high for wet underfloor heating. Therefore, mixing valves need to be used. We use RWC mixing valves and Grundfos pumps with our mixer packs to ensure the water is at the optimum temperature.

The heating engineer needs to size the correct boiler for the heating system. Normally, 3 kW is added for the supply of hot water. When a quote is produced we will indicate how much heat the system can provide.

The heating engineer or Architect needs to calculate the estimated heat loss for your project. If the property is built to current  regulations, the underfloor heating system will provide enough heat. Watch out for old, poorly insulated buildings and  properties with single glazing, these might need additional heating, i.e. radiators combined with the underfloor heating system.

Every order of one of our systems comes complete with a full set of manuals, a hand sketch and project information.
