Underfloor Heating Pipe Layout
The pipe is laid at 200-300mm centres dependent upon design.
Care must be taken to protect the pipework whilst installing the screed. Finally the floor finish is laid. Underfloor heating works well with almost any floor finish; tiles, carpets (use carpets with a resistance of less than 0.15 m2K/W), timber floors, plastic etc. The floor coverings and the adhesive must be suitable for the temperatures that underfloor heating will provide, the maximum temperature they need to resist is 40°C.
Please Note:
Always check with the manufacturer of the floor covering if it can be used for underfloor heating. Timber floors need to have a moisture content below 10% to avoid shrinkage. The system must be operated for 21 days with a very low temperature to dry the screed, then the floor covering can be laid. Also note that the screed must be allowed to dry for 6 weeks before the underfloor heating is operated.
