In-floor, hot water (hydronic) radiant heat systems work well with hardwood floors when site conditions are managed according to manufacturers' recommendations. The opposite is true when conditions are not managed properly. Ambient relative humidity; air, surface and product temperature; subfloor and product moisture content, all must be maintained within specific ranges. Thermostat temperature controls for rooms must be connected to regulate heat 24/7. Without proper management and site control, thousands of dollars or perfectly good product and installation work can be quickly ruined. Surface temperature, as in this image, is most commonly overlooked. An overly hot surface can cause splits, checks, delamination, gaps and buckling in hardwood flooring . Many manufacturers, for example, advise a max surface temperature of 28c (82f). Always check the installation guidelines that (should) accompany the product. Avoid products that do not provide detailed installation guides. www.nfca.ca
