Underfloor heating Insulation Boards - worth it or not

[KevBristol]

Hi, Im after a bit of advice re underfloor heating insulation boards.
Im getting electric ufh in my bathroom. Total area is approx 5sqm. The bathroom is above the kitchen.
Is it worth getting the insuation boards or will it be OK just to lay the cable on ply using the primer that comes in the kit.
The floor is going to be tiled.
Cheers - Kev

I would get the insulation boards if I were you. These will ensure you get the heat where you want it.
