Alright Chap's...!
Fair bit going on today.....but then again it is poet's day....so I left work a little earlier than usual.....(more on that later!).......
but today I am going to show you how we install an under floor heating system..........and here we go:
first of is.....make sure your mat will fit.......measure the area and DEDUCT 10% (as a rule of thumb!) from the whole area and round DOWNWARD.....
so if you have 4.6m2.....less 10%= 4.14 = (rounded down) 4.0m2 mat......
install the mat in neat runs and onto stage two.....
All heatmats have an "End"....this is thicker than the main "heat" wire....so it will need to be buried..........
so cut a hole in the insulation where it will end and ......
stuff it in!!!!
On some heatmats.......(these are warm up).......there will be some overlap of mesh.....(keep the heat wire at least 40mm apart from each other!)......like this...
on the heatmat I supply and fit thsi is never a problem on on warm up mats it is a constant issue....the answer is to take your time and trim it back!!!!
Like this: (and it will also give you the ability to apply gaffer tape across two runs and have them BOTH stuck to the floor!....warm up mat's dont stick very well IMO!)
If you need to bury tour "Cold Tail"......its the same procedure as the "end"........
This little bit of tube most people often overlook......
but it is the most important part of the installation......Because:
1. it is the most difficult to fit.
2. it is vital piece of futureproofing your underfloor heating install........
there are no guarentees without this tube!!!!!!!!!!!!
it needs to be cut to a length that will reach 50% into a heatwire run and up to your RCD....
in this case I needed to tape up the end......some manafacturer's proivide rubber bungs!.......
cut a channel in the floor and.......
stick it in.....
if your floor temp sensor ever fails you will be able to feed in a new one without having to damage the floor.................BONUS!
Finally coat with a cover of latex screed...this will encapsulate the heat wire and provide maximum heat spread from the wire.....as there will be no voids!!!
Best wishes
