form of underfloor heating can be very effective and the best way of looking after a timber floor throughout its lifetime, if you do it right.

Recent changes to SAP have had the

effect of giving a building a better energy rating if it has UFH in a timber floor than if it has UFH in screed/concrete. The improvement in SAP is sufficient that, if a house has timber UFH which is powered using a ground-source heat pump, a house which would otherwise be rated Level C could instead have the potential to be rated Level B. The most important reason for this is because timber floor constructions have lower thermal mass than screed/concrete and this enables timber UFH to change heating power output more quickly and with a smaller injection of thermal energy. However it is important to make

liquid screeds are laid over the top. Fixing clip-plates across the top of the insulation and then plugging the pipe into these protects the pipe and holds it securely in place while the screed or concrete is laid.

Many buildings in this country are now constructed with timber floors. There are some flooring companies and even some

underfloor heating suppliers who say that underfloor heating should not be used in a timber floor because timber is a poor thermal conductor.

This is because they have either not used the correct form of underfloor heating in the past or simply because they don't have it in their product portfolio. The truth is that the correct

sure you choose the right underfloor heating system for timber floors. Not all systems work in the same way some require very high water temperatures to be effective. So it is important to ask the supplier for independent heat output test data to make sure it will provide enough heat, especially when using a heat pump.
