Hi guys, a customer has asked me to look at installing underfloor heating for them. i am completely new to this and dont know where to start to be honest. I want to say no but i am also good friends with her husband and so feel as if i should do it for them.
They are having their old wooden floors plasterboarded over tomorrow and tiled in a few weeks time. i have read little bits about the heating but i want to know if anyone can point me to the key points.
IE: the old board doesnt have RCBO protection in it and i would probably struggle to get a new circuit pulled in anyway. Could i put it on the kitchen ring?
where do i even start with a system like this?
is it worth the hassle seeing as though i have never dealt with it?

Feedback much appreciated

Come off ring, Rcd fused connection unit then from there to the room start. U must install a temp sensor within the matting.

Depending on the loads of head heating ect
 
fcirst the ufh must be rcd protected, no ifs or buts. second, allow for about 1" rise in the floor level to allow for the insulating tiles under the ufh and the tiles over it, inc. the ufh itself. lastly, if it's all so new to you, eithewr turn it down or get someone with experience to shere the job. any problems after it's been tiled and you'll be facing a hefty bill.
 
yep im thinking of turning it down, sounds like too many potential traps.
as for the plasterboard over the old floor... my understanding is that the guy fitting the new kitchen is boarding over the existing wooden floorboards, as they are not all level, and then tiled.
its very strange. I have been told that it is plasterboard but i dont know.
thanks anyway guys, at least this means more time to revise for the 2395!

My advice is if you want to stay good friends,turn the job down, its not a particularly hard job to install underfloor heating but no way should you do it for the first time in a friends house.
Ps..no way on earth is anyone plasterboarding a FLOOR??? :)

i hope not, my mate isnt a light chap!!!
 
There is nothing to be frightened of, it is dead easy to install, go to your wholesaler and tell them what floor the heating mat is going on and under, tell them the square meterage, they will make a mat to suit the job, easy peasy, seriously, nothing to it.
 
It's more likely to be ply laid over the old floors.

Electric underfloor heating sounds good until it fails.

I've got 2 jobs this week looking at UF heating faults.

Both < 2 years old.

1 likely the controller 1 certainly the mat.

Both are customers I advised not to use electric UF heating.
 
You test the mat before covering it, if the mat then fails due to a badly laid floor then it is the floor layers problem, I have never had a mat fail, not once, think twice, measure twice and fit once properly.
 
LOL, I test the mat as per the instructions to make sure the reading is correct and all is okay, I then show the electriciansforums, once the floor is down I test again, if the mat fails then the electriciansforums pays for a new mat haha.
 
1 test mat out of box. Check resistance and insulation readings against data sent with mat.
2. After laying mat check both readings again.
3. Cover mat with slc and check third time. Then tiler can do his job.

Record all readings at each test. Mat instructions will probably tell you this anyway and have boxes to record readings of 1 to 3 at each stage.
