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...s*it..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.
