I just finished putting in a Do It Yourself radiant heat (hot water) system in my bathroom, documented here:
Thanks. You can reply to this address, it's a spam address, but I'll check it for the next couple weeks.
Looks okay but a couple of points.
1) did you leave any air space between the insulation and the copper tubing?2) Soldering a copper line in an enclosed space is something I don't like to do.
You probably did okay with the copper, but for the future job, I consider using PEX. You also want to think about reducing the water pressure in the system. I think the system will last longer.
BTW, did you install any kind of check valve on the water supply line?
Yeah. There's about 3 inches of "air space" below the tubing and above the insulation, and about 3 inches of "air space" above the tubing and the floor above.
YOU ARE RUNNING POTABLE WATER THROUGH THIS SYSTEM WITH NO CHECKVALVE?
Oh...shit..thats almost funny, if it wasnt so sad.
I'm sorry, I misunderstood.
The answer to your question is "no".
My only thought was that I wondered why you pulled up the sub-floor? Why not just put tube over the sub-floor in a layer of mortar and set the tiles on top? Some drawbacks could be extra floor thickness and maybe you wanted to add extra insulation below - I guess.
I'm going to do my whole house (I'm in the middle of a major renovation) with a thin slab. I'm wondering what DYIs do? I want to minimize weight and thickness.
Thanks R
Congratulations for completing the project. I have seen heated bathroom floor using electric mesh (net) underneath the tiles. I dont know which one is more (energy) efficient and conventional?
Iam still scared of soldering (lead) or welding. Once I get off that point (or get hold to the toys/tools) I may try.
Good Job.
Sam.
