I have some of this in my master bathroom. Is it common to do a whole floor this way? Is it electric heat or hot water heat? Looks like a large house you are building.
@randystreat We are building a "passive house" so the entire house is highly insulated. We'll use geothermal energy and it will be hot water circulating under the slab. It will be 5000 square feet for the house and another 1400 square feet for the heated garage.
