in THE MAIN WALL
I have a customer that wants to install Warm board with a 2 1/2" solid bamboo flooring. Has any one used this combination before. The build up of the floor is 2 layers of 3/4" plywood, 5/8" Warm board and 5/8 bamboo flooring over 6" joist with R-90 insulation, have access under the house. Also using a Munchkin boiler, will I need use a mixing control for the loops under the bamboo, what's the best way to set the boiler for this type of flooring. Thanks in advance for all you guys advice.

    Works great

    I have done two jobs with bamboo. First was a warmboard the next a slab application.

    Curious about the floor though, two layers of 3/4 then WB??

    WB is generally 1-1/8" unless you have some of the old retro fit 5/8" product? Didn't think they offered that anymore.

    Also seems like a lot of load on 2X6 joists.

    A heatloss calc & design should spell out supply temperatures. Generally WB operates at very low temperatures with it's excellent heat transfer surface. No reason to use a mix valve, I'd run the Munchkin with it's internal outdoor reset function for optimun efficiency and comfort.
