I’m no expert but I think you need to put levelling compound at 10mm thick over the heating wire first before any floor finish. The 10mm levelling compound dissipates heat evenly.

Hi Ed, Using our 160W/m² electric underfloor heating mats, you certainly can lay lino over the top, providing you first lay at least 10mm flexible self levelling compound. We hope that helps, but if we can offer any more advise, our friendly technical team are always on hand to help. Just give us a call today on 01772 761333. Thanks, The Snug Team.

spread adhesive under mat, lay mat, spread adhesive on tile. best result

yes you can. i did and it turned out fine

Hi Andrea, Thanks for watching our video, we trust you found it helpful. Our boards are absolutely fine to be used on either concrete or wooden floors, so you won't have a problem. If you are using the boards on a concrete floor, we would recommend fixing the boards down with flexible tile adhesive. Feel free to give us a call on 01772 761333 for more advice or if you have any questions about choosing the right underfloor heating solution for your project. Many thanks, The Snug Team.

Hi David, Our levelling compound is made by Rocatex. The fibre-reinforced self-levelling compound gives heating mats and cables extra protection - ideal before you begin tiling the floors on a project. Why don't you give us a call on 01772 761333 to discuss your project? We would love to hear from you.

What is your application voltage? 120 vac? or 24vac control? Self sensing, don't forget that. Regulated along the run.

Does it matter, it did the job!

Have you listened to the video ?

@@shirleycarter9210 no, too long to listen to.

Hi Joe These boards were put down straight onto a wood base, if you are putting them on a concrete base you would need to drill and rawl plug.

@@firsttraceheating or use tile adhesive?

Hi Patrick, they are a thermal construction board that we (snug) sell and are available and any electrical or wholesaler. Our part codes are Thermboard-6 for 6mm thick and Thermboard-10 for 10mm thick.

@@firsttraceheating thank you

@@firsttraceheating Are these thermal boards resistent to high temperatures of the electric mat?

Hi Tom, Happy to give advise on your installation. If you would like to call us we'll go through things in detail with you.

No you don't want to install under any units, you can install up to them but not under them.

Thanks for your comment, it can be part of the ring main but we would recommend that you install a fused spur and then connect that to the controller. That way you have local isolation. An RCD should be on the circuit somewhere, whether that is by the board or an RCD fused spur. If it is coming off a ring main you would want to use 2.5mm2.

@@firsttraceheating Thanks for explanation. Is it just specifically used in bathrooms or they can be used all over the house?

@@hamidbazmi7948 It can be used in any room in the house. The mat in the video is designed specifically for under tiles, if you have other floor finishes then we mats to suit as well.

@@firsttraceheating Thanks again. I guess with 100_300W it would very cheap and efficient to run it.

If we run underheating system throughout the house, do we still need radiator?

It all depends on how dusty the surface is. the primer is there to absorb the dust so that the levelling compound or tile adhesive can get a better bond to the subfloor.

Hi James, The boards want to be fixed down somehow, in the video we used screws and washers as the subfloor was wood. Fixing with boards using a tile adhesive is also ok as long as its flexible tile adhesive.

Yes you should test the mat at 3 stages, firstly when its on the roll, then once the mat has been aid and then finally after you have tiled. You should get the same readings on all 3.

not true I am afraid. You need to spread it from the lowest place.

As a rule of thumb 30% of your heat will be lost when insulation boards are not used.

Thank you. Is there any alternative to insulation boards? These would raise the floor level of our retro fit in ensuite

The system will still work fine without insulation boards. The boards just make your running costs lower and your heat up times quicker. The boards come in both 6mm and 10mm. Unfortunately there isn't a thinner product that will do same job as the insulation board.

firsttraceheating aerogel Matting? in sizes of 1mm 5mm and 10mm thicknesses

Not that I know of, the issue would be the number of variations in tiles and also the floor heating cable has to be in one continuous length so you would need 15 different variations of the same tile to suit different room sizes. Times that by 200 different tiles a shop may have and the cost would make it not viable.

Thanks for the comments! Yes you can place tile adhesive directly on top of the floor heating. The levelling compound is only an option as it helps protect the cable from being damaged during tiling.

Hi Michael, We would recommend that you remove the laminate unless you would be placing another laminate over the top. As the wood will move you really don't want to be leaving that down if you are going to be putting a screed or tiles over the top.

Hi Ian, Are you struggling with measuring you room or with the selection of the mat size? The easiest way to work out your free space is to get your full room size then minus off your units i.e. bath, toilet, sink, shower. Then once you have this measurement deduct 10% and go to the next mat size down. If your free space is 10.5m2 You would want a 9m2 mat. If in doubt you always go for a smaller mat than bigger mat as you can not cut the cable. I hope this helps, any more questions please let us know and we'll be happy to help.

Yes you would run the levelling compound right up to the soil pipe as the tiler will be tiling to that point. Where ever you have tiles you want the subfloor (floor heated or not) to be an even height otherwise the tiler will need to build up the floor with adhesive which is more labour intensive.

firsttraceheating does the power supply go to a low level spur ie socket height? Or directly to the controller?

firsttraceheating 1 second ago Ideally you want the power to come from the mains, to a fused spur then to the controller. That way if you ever have to isolate the underfloor heating you can without isolating the whole ring main.

firsttraceheating thanks
