    hot water radiant heat in bathroom

    When laying out pex tubing for HOT WATER radiant heat in tiled showers, can
    you expect the contractor to run loops in the concrete shower bed or at
    least along the wall?

    Just wondering because of the slope required for drainage.

    Thanks.

    expectations will get you nowhere.

    Ask the contractor.

    Then inspect the work before the concrete goes in.

    That depends on your layouot.
    You need to meet with your HVAC and concrete contractor to go over the install.

    How many times must one fix something before it is fixed?

    I would talk to a plumber. Try http://www.terrylove.com/forums/forumdisplay.php?f=6 and see if they can help. My "guess" is you can run it on walls but the floor is the way to go. Especially is it's on an exterior wall.

    I don't know about your area, but around here plumbers only know three things and hot water heating is not one of them.
    Karst means cave. So, I search for caves.

    the shower has to be framed out seperate from the rest of the room due to having to keep water in that area and not letting go anywhere besides the drain. the lines would have to run over the "step into" of the shower and then down into the shower. not an easy task. my shower has no radiant heat in the floor and my feet are warm during the whole process

    We ususally radiate one interior wall of the shower unless it is slab on grade, in which case, under the shower it goes.

    That's interesting, I never even thought of doing a wall. Do you put it
    behind the water proof board whose-name-I-can't-remember? I want to
    make sure that when I say I expect hot water loops run under the
    shower floor and along the exterior walls in the basement that the
    usual response should be "well of course" rather than "we never do that".

    I'm in St. Paul by the way. I'm hearing that the city is a little particular
    when it comes to hvac. I was interested in a weil mclain indirect
    DHW storage tank and apparently you "have to" use an Amtrol boilermate.
    I've never used either but the Amtrol seems less robust that a weil mclain
    and on paper the specs aren't as good but I'm not the inspector.

    The walls in the shower will work nicely with tubing run though them. Do a wall in the bath and hang a towel bar in front of it, it's a poor mans way to have heated towels.

    If it is going to be inspected in the cities it has to be double wall, even though the state does not require them and they are sold in 150 countries by Buderus without double wall.

    My biggest complaint with Amtrol is the awefull performance and hard service. Weil McLain is one of my favorite indirects! More than safe in a single wall model and last forever.

    I just installed a top down model last week and remembered why I still dislike them so, compared to any other brand. I imagine that is one of the reason they are bankrupt.

    I will put them in but under protest.

    That's such a clever idea; my wife would love that. Do you staple it
    to the studs or mount something in the wall? I'm wondering if our
    heating guy would be able to use the wall has the plumbing mounted in it
    without this costing a fortune - we're already over the budget and
    the backhoe hasn't even been ordered...

    Well that's even worse than I thought although they actually have
    exited bankruptcy. I'll have to nudge my general contractor to get
    the hvac vendor to find something else. Got a favorite double walled?

    Nice website. I bookmarked it in case my gc's sub death-rolls.
