Radiant Heat under exotic woods?

Anyone had much experience?  Brazilian Cherry, Tiger wood (not the golfer),

Mahogany?  I want to tell the homeowner that it will be fine, would like some backing from completed jobs.

    Stay away from Brazilian Cherry

    I have a floor  that did not do well with B Cherry, I believe that the hard wood floor institute would not recommend this installation, the other woods I have no experience with as a flooring product. Good luck Mars

    woods work well

    providing the radiant system was designed properly. Haven't yet met a hardwood species I don't like for a radiant floor. Follow the RPA guidelines & you'll have no issues. We have thousands of square feet of radiant hardwood floors with not one single problem except for the occasional lunk-head puncturing tubing. Our contracts spell out who pays (the GC or owner) when tubing is damaged by other trades because they control the money-flow and can divert funds from the responsible party.

    The secret to success is in the design and control. I've seen and dealt with damaged hardwood floors when the installers ignored sensible guidelines while striving to be cheapest to win the bid. Hi-temps and hardwood-hi-moisture-content don't play nice.

    It's all in the stat!

    I personally use Upinor 501S stats to monitor floor temps and set a max to make sure the floors don't look like like a scaled down version of surf waves. Another good aspect of the setpoint stat is that you can maintain a constant floor temp which customers love. Is usually a quick upsell in a house installed by someone else!
