We are renovating an old stone house and planning on having under floor heating on the ground floor. I know ceramic tiling works very well with this heating (which is what# will be in the kitchen), but we'd like to have wooden floors in the living room. Are there problems/issues with under floor heating? Our builder thought there might be warping if the moisture content of the wood is too high - we live in a very humid climate (Ireland) - similar to Oregon - if that is also an issue.
