Some Advice For Tiling Kitchen

[Swindiff]

I know it would be cheaper to run, but for my situation just to much of a pita to install 🙁

Look into this Schluter system, it radically reduces height of required screed, it's a wet system as opposed to electric. So although initially more expensive, far more economical running costs.
Sounds ideal for your situation.

That does look interesting, cheers. I have emailed them to find out prices, am dreading what they will come up with lol

Electric it is then lol. Over 4 grand for that system. About 10 times the price of in screed electric heating. No way I could justify spending that sort of money on it. Cheers anyway.

So all the flooring is now up. I can manage to get in 50mm of insulation and 60mm of screed. Just wanted to check my plans with guys in the know that may have done this before. Floor is block and beam construction rather than a poured concrete base, see image.

Lay a DPM over the block and beam concrete floor, leave plenty up the walls

Lay Celotex 50mm insulation. Which should I use? The most common seems to be Ga4000, but I have also read that Celotex tuff-R GA3000 is suited to underfloor heating (fibres to give extra strength) is this necessary?

Tape all the joints in the Celotex, should I use the proper celotex tape, or are you just paying for the name, will general aluminium tape do?

Should I have another sheet of plastic here. I have read a 500ga seperation later on top of the insulation is a good idea?

Install the in screed heating system. I have come across a few (3 links here), which is best, or are they all much the same?

Install expansion foam around the walls to allow the screed to expand when heated

Screed over up to a level of 60mm. I will be installing a fiber screed for added strength for expansion and contraction of the heated floor.

Am I missing anything, any tips?

Cheers

Don't know why my photo links are not working. Tried one from google drive and facebook

Edit: Posted as a link rather than an image seems to work

Also considering something like this, really depends on what the guy who is changing my boiler says. Wondering if the pump will fit in same cupboard as the boiler and if it will how quiet it is.

This is what I have come up with for the Polypipe system. Any obvious errors?

Should I post this in a different forum, its more underfloor heating at the minute rather than tiling?
