How does a SunTouch electric radiant floor compare to a hydronic (water based) system?
In general, hydronic radiant systems are most often installed in New Construction, not remodels, especially whole houses. You need space in your floor (up to 1-1/2″ thick) for the tubes and a Boiler or water heating appliance and the pumps, valves, manifolds, expansion tank and fittings that accompany it; plus a mechanical room to hold this equipment. Hydronic systems allow you to choose the lowest cost fuel, which might be natural gas, oil, propane, solar, or electric. SunTouch is an electric system. SunTouch mats are used most often in smaller (less than 1500 Sq Ft) remodel environments, although we have done a Large project of almost 8,000 Sq Ft under Carpet. SunTouch is simpler than hydronic, takes up less space, goes in faster and for smaller areas, the per square foot cost is much lower. Once the system is installed, your floors will feel wonderful regardless of the approach you choose. Radiant Floor Heat is the best!
