UNDERFLOOR HEATING WITH MAXRAFT

Underfloor heating is not expensive to run when everything is designed correctly.

Either MAXRaft or MAXSlab can be specified with underfloor heating and they are a perfect combination. A fully insulated MAXRaft design will prevent heat loss at the edge of the slab where 80% of slab heat loss occurs and throughout the underneath of the floor.

Preventing the heat loss means the underfloor system isn't working as hard and can result in smaller units being specified and cost savings in both capital spend and running costs.

Underfloor heating is typically installed either directly onto the polystyrene (stapled) or tied to the top of the mesh. Where pipes are on top of the mesh a 120mm slab is typically required instead of the standard 100mm. It is best to talk directly to your Underfloor Heating supplier on which option they prefer to do.

 

 


This image highlights how underfloor heating can be expensive when a slab is not insulated correctly at the perimeter, such as with a MAXRaft system.
Here the house's underfloor heating system is heating the grass around the outside of the slab, which is expensive heat loss.
With a MAXRaft slab this would not occur saving up to 40% in running costs.
