This guys great, knows his shit

If you are doing a larger m² area can two mats be joined together to run from a single thermostat or is it better to install each matt separate?

[@bullychris]

They can be joined to a single thermostat. Just check the output you are trying to achieve.

[@davidprendergast9821]

So long as you're not exceeding the load rating of the supply or the thermostat. You can bring multiple mats into a junction box, connect them together in parallel before running a single cable to the thermostat's terminals. It's done this way so you don't end up overcrowding the terminals and causing loose connections and arc faults as a result.

Hi Could you please tell me what size notches trowel you are using just before laying the insulation boards at 5:00 timeline in this video. Thanks

[@theunderfloorheatingstore]

6mm square notch design. We sell this on our website if you search 'square notch trowel' in search bar

At 5:36 I’m laying these board with tile flexible adhesive on new concrete screed floor so question is need put screws and washers to secure the insulated board also. ? Thanks

[@theunderfloorheatingstore]

@@Skills_02 You don't necessarily have to, but if screws are impossible to fit you can use a glue that we have on our site

[@davidprendergast9821]

You only need to fix down with flexible tile adhesive onto concrete. No mechanical fixings are needed.

Are you leaving the lcd thermostat that low down on the ground ?

[@davidprendergast9821]

Yes, out of shot there are several backboxes with supply and network cables at the normal height. The homeowner didn't want the thermostat up there as well as it would look / be very cluttered. Where the thermostat runs on floor temperature using the probe anyway it doesn't really matter where it goes, especially as the one selected can be controlled from an app.

The stat is ip21 so could go in zone 3 for example

[@davidprendergast9821]

@@andrewlee4938 Agree that it would technically be within regs but it wouldn't be practical. It's a knowledge and wisdom scenario. Just because a tomato is a fruit, it shouldn't go in a fruit salad. The face has a grille that allows air in, the humid, post-shower air will enter the thermostat which will shorten it's lifespan.

I’ve just put 10mm of levelling compound down supplied by pro warm. How long do I leave to dry before I can turn heating on?

[@davidprendergast9821]

Leave ideally for 14 days, then turn on low and increase gradually. This is to avoid cracking any cementitious products that have been used.
