Is it a bad idea?

Ed, I'm sure you're a great installer and have allot of knowledge, but it's pretty rude to come on a forum and call a regular poster a liar straight up.

Allot of wax's have melted over the years. How do you think the standard was formed?

    Radiant under toilet.

    Is it a bad idea to run radiant under toilet location? I usually don't like running heat near toilets due to condensation, but it would make my life alot easier if I didn't have to go around it. Toilet is also positioned on outside wall. Running such low temps I don't believe it should be a problem but want to do the right thing. Anyone have any experience with this? Installation is quicktrack on floor, cementboard, and tile.

    Thanks in advance.

    Typically it's a bad idea in any case. However, these new neoprene seals solve that problem. We have been supplying them on our houses to the plumbers at no cost. They appreciate it and we don't have to lie awake at night worrying about wax seals! And it also gives us more surface area in the bathroom which can be a problem with so many cabinets.

    Typically, wax gaskets sit on floor flanges that are on the surface of the finish floor. Radiant floor surfaces run around 80-85*, I have yet to see a wax gasket melt away at that temp. I usually keep one or two gaskets in the truck all year, it probably gets well over 100* in my truck in the summer, and they still have not melted away.

    That being said I try to stay at least 6" away from the flange, no problems yet.

    melting temp

    Just did a quick search, toilet wax gaskets are mede with beeswax.
    Beeswax melts at 144* F-147* F, so as long as your surface temperatures are below that, no problems.

    I am less worried about thewax ring melting. In fact that thought never even crossed my mind. I am more worried about tank sweating. I have installed baseboard behind toilet at 180 and never once had a problem with a wax ring. I understan your concern as radiant is technically below and can effect ring but, that is not my real concern. Will a tank sweat with floor temps around 95 degrees?

    The only thing that makes the tank sweat is a cold tank (from cold feed water) and a moist room. Unless your radiation is leaking there shouldn't be any more moisture is the room. The biggest source for moisture is probably the shower. Keep that out of the room and you shouldn't have much of a problem.

    In reality, if the tank gets a bit warm it would be less likely to sweat!

    I wish I was that fortunate!! But yes, I have seen a wax melt before. Just because the floor surface area is 80-85, it doesn't mean that the wax is 80-85 because it has a nice little air bubble of insulation around it so the heat can't dissipate as easily as it could have otherwise dissipated uncovered.

    You are probly right though Sing in that a properly designed system won't have any failures. I guess the instance where I saw one melt was a little extreme in that the original installer had 140 degree water being supplied to a 4" slab with tile.

    melting wax

    please stop. You actually saw a wax ring melt on a radiant floor? Stop. Where did this bs get started?

    Toto toilets

    Some toto toilets and those dual flush coroma's have unique anchoring systems that are far away from the flange/t-bolts requiring bolts into the floor and don't forget bidets
