Do I need insulation under electric underfloor heating?

When fitting underfloor heating where should you fit insulation?

Place the insulation as neatly as possible and tape the joints to prevent screed from making its way underneath. If you are installing a wet system, the pipe fixing system should then be fitted on top of the insulation at a 90-degree angle relative to the direction in which the pipes will be laid.

Can you use Celotex with underfloor heating?

We recommend the use of Kingspan Thermafloor TF70 or Celotex FF4000 or GA4000 high performance thermal insulation under all our underfloor heating systems. These boards have a high compressive strength and high thermal resistance and are foil faced boards manufactured from rigid polyisocyanurate (PIR).

Do you need to put insulation under underfloor heating?

Insulation is a crucial consideration for UFH. Ideally there should be suitable insulation below the underfloor heating pipe to resist the heat going downwards. As you would expect, you need as much heat as possible to flow upwards and into the room.

Can you put electric underfloor heating on floorboards?

Underfloor heating can be placed on top of floorboards, or any other type of subfloor you require. In this case, a modern electric system would be best, as it can simply be laid out across the existing floorboards before the new floor surface is installed on top of it.

Can you lay underfloor heating on chipboard?

I wouldn’t run it on chipboard simply because it’s not an ideal substrate to tile onto and will be more prone to expansion / contraction than ply. If you want to, rip up existing T+G floor (e.g. if levels are an issue) lay 18mm Far Eastern WBP ply.

Can you put underfloor heating on existing concrete floor?

The simple answer is that adding underfloor heating over an existing concrete floor is usually impractical. … With relatively inexpensive-to-fit electric underfloor heating, the build-up above the insulation can be small, but running costs are normally prohibitively high.
