I'm installing in a garden room onto OSB floor. There is 60mm insulation in the floor frame. Is the 6mm insulation plate still required as there is already insulation below the OSB?

I find the existing intelligent controller a bit difficult to use - is this a replacement, can it be fitted easily, and is there any change in functionality?

Hi, I have 2x C16 installed from two separate fused spurs in my house.
When the fused spur is switched on and the thermostat switch is off, then each thermostat is drawing off quite a bit of power (nearly as much as when both switched on) Any ideas why this is the case, or if there could be a problem?
Many thanks.

Hi - my thermostat was installed for underfloor heating about 18 months ago and has been working fine. However there the thermostat seems to have died and will no longer switch on. Is it likely to be an issue with the thermostat itself or something else. There are no other power issues around it.

As a manufacturer, we ensure a 50-year guarantee so unless the flooring has been badly damaged by an external source then it is highly unlikely a fault will develop. If the pipes are damaged, you can repair and rejoin, however, we would not recommend this if the damage is made during the installation phase.

We recommend a minimum of 1 day drying time per mm of screed fitted. This may vary between screed manufacturers, and a better guide may be supplied by them

Yes as long as you are self-levelling over the mat, or using a concrete backed insulation board below, then there is no issues. Tiles can be fitted directly on top.

I’m looking to use it behind the towel rail/radiator in the bathroom at the bottom so the heat radiates up to dry the towels in the summer & I can switch off the radiator from the gas boiler

Yes, we offer systems for all types of installation, old and new. When mixing systems in a property of this sort, we would recommend insulation as a priority, to avoid heating discrepancies where possible.
