UFH Installed from Below ?

[58stand]

I've seen that there's a system for Under Floor Heating that can be installed from below. Anyone got experience ?

I've a beautiful Encaustic floor tiled hallway that needs warmed up ! Brrrrrr

 

[Zebra]

Weird! How?!

where? how? I'm also intrigued...!

obviously if access was feasible, heat transfer between the material encasing the UFH elements and the base of the tiles would be poor I imagine...

I'm having visions of a Heath Robinson illustration.

Can you provide more details? I'd love to see how it's done.

 

[TheForge]

It’ll be a between the joist installation,
I think one system is called Aluplate.

But this is a solid floor.........?

Anyway, ufh below a wood floor is bonkers.
Wood is an insulator.

UFH under something doesn't work.
UFH in screed, concrete, limecrete, whatever..........bliss.

Wow. Surprised no one had heard of this, there seems to be loads of outfits doing it.

I have a basement under the hall, so access relatively easy and a LOT easier than lifting the floor tiles ! I'm not looking for output to heat the place, more to take the edge off when walking around bare footed or suchlike.

It is obviously a proven system albeit perhaps a little inefficient, I just wondered if anyone had installed and could recommend or otherwise.

Radiantec type systems are very widely used under wooden floors in America - just watch a few episodes of 'This Old House' ...

Proven by who?

Looks like it may do an ok job of heating the room below...

I cannot see how this will transfer any meaningful heat to a slab sat above the pipes. I'd save the money and buy a nice rug...

. . . or a pair of socks.

Could really push the boat out and get slippers too... Although, our new puppy loves eating slippers so we are back to just thick socks!

What makes you think no-one has heard of it? I have, and similar systems.......and they are a desperately inefficient way of space heating. It simply doesn't work well enough to justify the effort. The best that can be achieved is to warm the floor slightly, but not the room. I am an architect, and have had countless projects where clients wanted to retro-fit underfloor heating in suspended floors. Those few that have resisted my persuasion have all regretted it. The whole idea is fundamentally flawed.........to the point of being, frankly, ridiculous.

Mike, do you know if there are any reports or studies of such systems? I'd like to read up on them before I discount them, because I'm buying a listed property which has no heating in half of it, and the flooring in it is a mix of wood floorboards and parquet flooring. So looking into all the options of heating the house.

 

[MikeG]

No, I've never needed anyone else's opinion of these things when my own experience has been so entirely negative. If you've fallen off your bike 4 or 5 times, and it's hurt like hell every time, you don't need someone's study to tell you that falling off a bike causes pain.

Hope the purchase goes well.

Ufh is not a means of heating a wooden floor. Wood is an insulator. It does not transmit heat. The notion is marketed by cynical characters looking for mug customers. Don't be one of them.
And If you could shoehorn it under vintage parquet, it would eventually warp and loosen the parquet.

Radiators... cast iron of course... in rooms with parquet or where you don't wish to lift the boards, drop the pipes from upstairs, in the corner in boxing or behind full-length curtains. After a while you won't notice them.
Then along the skirting in proper old-fashioned skirting clips https://www.colglo.co.uk/productlist.php?category=Brass_and_Chromeplate_Skirting_Clips which can be painted or not.

Sure, but I just figured that as there seem to be quite a few people selling these systems, that there might have been some reports covering it's efficiency or lack thereof. I like to do as much research as I can where possible.

My dad DIYed an UFH system under marble tiles back in 1981, and that was efficient.

Thanks for the point about wood being in insulator, I had not really thought about that. Or the parquet warping. Guess I can discount that option then.

Thanks for the ideas. There are internal shutters on the windows, so no curtains, and boxing in the corners wont be suitable I think, as the rooms with parquet have nice oak-leaf cornicing.

Mmmm, but curtains could be introduced... ?... and as to the boxing, http://www.wheatleyplasterwork.co.uk/ornamental-plaster-products ...'Reproducing cornices to match current installations is an expertise of our team!'

Ditto the skirting and picture rail, then once the room is papered, the boxing will vanish.

Bit of a hassle, but need only be done once.

When the Lloyds 1921 building was demolished in the 70s, I bought several yards of the oak parquet, ignorant of the fact that it had been bedded in hot bitumen. In addition to being on the backs, the bitumen had flowed into the joints. I dare say it could have been rescued, but was quite beyond me and my blowlamp at the time. Eventually sold it. I hope it had a second life. Do like a nice bit of proper inch-thick parquet.
