Water heating mat

[Christophe]

The V3V in a pinch we can do without; in thermal and delta of T ° which can the least can the most ... will just not have to walk barefoot

Otherwise integrating it into the carpet with a "fixed adjustable" bypass would be an easy solution.

The idea is not bad at all, it would not be unpleasant, but to sum up

- thickness problem
- problem with chair legs and heels
- 3-way valve
- watch your feet in the inlet pipes

what else ?

problem with chair legs and heels

...Yes
Perhaps design a carpet with many pipes, which will allow to plug a number by crushing ...?, Without cutting the entire circuit; short work with pipes in parallel..or other ... a bit like the venous circuit of the human body.
Thickness..yes, it's also a small problem; but hey, there are very thick Persian rugs too.
For Cristophe, are you talking about an electric carpet ... has there already been any work on profitability in this area on econo? (already for those who have photovoltaic sensors, it may be profitable)

Good evening, I had already had this kind of idea but with a mattress to be warm in bed, for the carpet there are flexible and very hard materials to avoid crushing the pipes with chairs or other furniture

the idea of ​​the mattress connected to central heating was an idea of ​​an ongoing project in college but it was a long time ago, in my class others had the idea of ​​armchairs or sofa heated in this way

[Grelinette]

I also think that the idea is interesting and can surely be improved.
For example one can imagine a kind of tiling whose tiles (of shape, size and variable thickness) contain a tubular network and interlock with each other so that they can cover any surface.

It also makes me think of solar panels: a few years ago talking with a specialist, I said jokingly that the ideal would be solar tiles that fit together and connect electrically to recover the current produced. Like this, no need to install PV panels, just remove original tiles and replace them with solar tiles of the same profile.
At the time the specialist had told me that it did not seem possible to him as a concept but I saw on the internet that it has been released since.

Like what, between the turf, the heated floor in tiling or carpet, the roof in pv tiles ... we can transform a house!

I do not think where I remember it more, cold I would say that the gain over the year compared to a convector will not be amazing (really fishy: 30%?) And I think much lower than that of a good reversible heat pump (COP> 3).

The gain would be mainly in terms of comfort, for example, having your feet warm in a bathroom.

Otherwise I think we could estimate the gain by comparing a house with conventional radiators and an equivalent with LV installation and PCs ...

[Flytox]

If originally it was a glaring problem of space, there is also the solution to put the radiator (all flat) on the back of the door. All it takes is a flexible fixing of the pipes and a good hinge.

+1
I would add problem of loss in the ground ...
A heated floor is placed on an insulator so that energy heats the room instead of the floor ...
The problem can therefore arise here too.

Yes, I had thought of that, nothing prevents putting an insulating end to the bottom of the carpet

[elephant]

Yep! this carpet will soon become a podium!

[dedeleco]

All you have to do is take the solar thermal collector in Christophe's summer PDM for swimming pool and pass lukewarm hot water through it to heat it up !!!
Cheap !!!
