Re: Electric under-floating-floor heating 9Aug 27, 2014 11:36 am Mcarthur, For timber floors, there should be a floor temperature sensor that limits the timber temperature to 27deg C. That value is based on the timber flooring being quarter sawn, engineered timber with moisture content of 8%-10%. 70W/sqm is possible if the room temperature was set to 20deg C. In addition expansion joints within the slab should be extended to floor surface level and for any areas greater than 40sqm and between door ways an expansion joint profile is recommended. Mate, I do roughly 5 installs a month for retro-fit hydronic between timber joists. If you have access under your floor - that will save you having to rip the flooring out. But, if you are changing the timber flooring anyway, it makes sense to go hydronic. I recently removed electrical floor heating that was costing a customer $3000/quarter for a 200sqm home running on a timer for on average 3-4 hours per day. The heat output varies of electric systems between 150-200 W/m2 (but only in bathrooms!!!). For a 10mm timber board, my calculations (I'm a Mechanical Engineer) show heat outputs of roughly 100-120W/m2. I'd be glad to assist if required, feel free to give me a call.
