Snow Stair Detail

Zman Member Posts: 7,543
Does someone have a detail for snowmelt in stairs they would be willing to share?
It will be 5/8" hepex tubing. I thought I had one saved but am having trouble finding it.

    I've always been impressed with Johns snowmelt design and detail at ART in upstate NY.
    He shares about 10 snowmelt jobs at his site.


    I liked the MultiCor method with tube running up and down the stairs.

    I recommend at least 4 tubes across a tread and one close to the nose of the tread as it has two cold surfaces to warm.

    Keeping the tube up in the pour is critical. You want 1- 1-1/2 times the aggregate size above the tube, so at least 1-1/2" of concrete above the tube.

    It takes a lot of careful prep work to get it right, having the plumber work with the concrete form guys is a key to getting it right.

    I love your profile pic. Are you gonna connect warm water to that bed frame?
