Under floor (tile) heating

[LetsTryAgain]

Hi all.

Having to do some under floor work in the kitchen and using the opportunity to replace the carpet tiles with something a bit nicer.
Tiles will be going down after the work is complete and I'm wondering if you can get decent enough under floor heating to go through decent thickness tiles?
Any and all help appreciated.

Thanks, Stuart.

Tiled floors are ideal for under-floor heating! Almost every five-star hotel bathroom in the world will have tiled underfloor heating.

Does it matter that they're quite thick?
Well, I suppose they're maybe 1/3 of an inch thick so that's not terrible.
Basically, I don't want to go to the expense of putting it all in if it's not going to be felt in the room.

It will go through any tile thickness no problem, it's just a matter of setting it to come on earlier and turn off earlier depending on the thermal mass of the tiles above it - which you will find out once it's all done.
Make sure you have insulation underneath it though, or the electric bills will be even more extortionate than they will be anyway - there is no such thing as cheap and effective electric heating.

Thanks for the reply.
I have seen water underfloor heating kits, which I assume run off the central heating.

Do you think this will be a better (cheaper!!) option?
I am 'in' the central heating system anyway as a result of the work I am doing to the kitchen, so it wouldn't be much trouble.

I have had to remove a radiator, basically. So now wondering what would be the best way to heat the kitchen in the future.

Good afternoon gents.

Thanks for taking the time to respond; some very helpful points raised and questions asked!
Concrete floor, so I suppose I’m stuck with electric UFH in reality.
I’ve just ‘dug’ a 10” wide by 8” deep hole in that so I really don’t want to be doing that for the rest of the floor.
I’ll have another read or two through the responses and go from there.

Thanks again.

Is it a new enough house to have decent insulation under the slab, or is it concrete then soil?
You can have a groove for wet UFH cut into the slab, but that's only really worth doing if you have insulation already there - otherwise it'll be a big difference in floor height, or a bit of a bodge with ally heat spreader pates that will still just dump most of the heat into the ground.
https://www.outsourcedenergy.co.uk/in-cut-underflo... - never used this lot, just an example of how it can be done.

Thanks for all the help.
Nope, 30's house, and I've dug it out and got to soil.
The pipes (feed and waste) are sat within a 4 and a half inch pipe with two 90 degree ends so i can refill the hole with concrete but both the pipes remain free from it.

The point of removing the radiator is because it takes up space for 3 'appliances' which i'd rather have stuff in than big old radiator which I can't put anything in front of.

Will post/read more etc later.

• Later*

I was going to fit the radiator which I removed to the opposite wall, vertically.
The main reason for all this work is that due to an earlier extension, the layout isn't the best for the size of the room.
So rather than lose 3 appliance spaces under the counter due to a radiator, it's been removed.

Also, hadn't given the insulating boards any thought, to stop the heat just disappearing into the ground below!

Thanks, that'd be appreciated.
Where did you get your stuff from?
Is it possible to get a 'turn key' kit, as it were?

I've found this site, but it's difficult to know what items I need!
More research required I think.

I bought most of the kit from "the underfloor heating store" l. They supplied the low profile insulated sheets with pipe grooves, pipe, did the room layout, manifold etc...

This sounds like a 'wet' kit, is that right?
I like that the LP insulated boards had recesses in them for the pipes.
That will help keep the 'raise' in the heigh to a minimum.
What sort of size room did you do and is it any good?

Thanks, LTA.
