Just had a conservatory built and thinking of installing some underfloor electric heating but have a few questions .

1. the room is about 12 square meter , most kits are 6 max , do we need 2 or is 1 suficient ?

2. The floor has been insulated to the max , and then screeded , do we still need to add insulation underneath the heating or can i just stick to the concrete .

3. finally , we are thinking of laminate flooring as a finish , what do we need in between the heating and the laminate ?

thanks , going to B and Q in the week , but a bit of knowledge before hand could help save a bit of time and money

I’d have thought about it BEFORE you built it…

If you only use 1 kit, the tiles won’t get very warm. Depending on the switching capacity of the thermostat, you might be able to put 2 loops into 1 stat.
You can put the loops straight onto the concrete and tile straight over, use a good flexible adhesive (BAL) and make sure the tiles are suitable for UF heating.

finished flooring is not in yet .

Is it the prmary heating source ? :/

Not sure why you think you can only go up to 6m ?

or look at their ebay page which sometimes has the same product cheaper

I would look online at a specialist – it will be cheaper than B&Q and they will supply a suitable thermostat kit for that area.

We bought ours direct from Enerfoil 10 years ago, it was great quality and good instructions. All still fine now according to pals who bought the house off us.

All still fine

Yep of course it is …. what can go wrong? … it’s just copper wire.

Well that’s my take on it…. get the cheapest you can find, no point paying a premium for any kind of “brand” …??

The thermostats are more than wire – and can go wrong. Enerfoil were seriously cheap, much less than local diy chains.

whats the worst that could happen – y’know leccy n all…

but if your happy with that just import no name chinese shite off of ali baba – cut out all the middle men, no point in going half assed.

If its good enough for the Beeny …. its good enough for me 😀

thanks all .

Late reply.
I have done this in my Conny.
Was struggling with depth due to French doors opening into Conny so only had so much room.
Have a measure up. What you need is this.
Line out floor with thick Bacofoil.
Lay on top Tile backing boards the Cement/Fibre type otherwise you’re wasting your time as half of the heat will go down.
I had to fit Flat cable as its thinner than the round stuff. X2 to cover floor area.
Then lay some Laminate foam or the thicker type underlay if room allows.
Next you can get different thicknesses of Laminate again depending on room.
I went down the thicker underlay, thinner Laminate route and have a 2mm gap under the open doors.
After all that I ban the wife from flicking the switch as its to costly to run. 😀

Hold on. Never mind the quality of the wire and all that OP.

You’ve gone and (1) built a conservatory and (2) are thinking of putting heating in it?

It would be less aggro to cut out the middle man and keep yourself and the sky warm by burning piles of £20 notes….

Shouldn’t electric underfloor heating be sunk into the screed not laid on top of it???????

I used these heating mats from this place http://www.underfloorheatingworld.co.uk/under-laminate-heating/1sqm-under-wood–laminate-floo/

Dead simple to do you lay insulation mats (supplied as part of kit) straight on top of concrete, then heating film mats that are about 1mm thickyou probably need 3 or 4 from memory they are 3 metres long and 1 metre wide but you supply them a diagram of your conservatory and they work out how many you need. Then just a moisture barrier on top (again supplied) and then your laminate. With laminate you are only supposed to run your heating to 27 degrees which doesn’t sound much but it heats mine fine and floor is a lovely temperature to walk on.

You’ll need an electrician obviously to wire the mats up to the mains and the thermostat but was a very easy job to do.
