How about an electric immersion element as a heat source for in-floor radiant?
I called on a potential client today in climate zone 5 (Northern Ohio). He built his home 20+ years ago with double studded walls, fiberglass insulation and a passive solar design. The home is approximately 1800 sq ft on two floors. The main heat source is an in-floor radiant system installed in the floor of the lower level. There is no heat on the second floor. What struck me was the beautiful simplicity of the radiant system. There are four loops of 3/8" pex installed in aluminum covered plywood panels with additional plywood and a hardwood floor on top. One small Grundfos pump circulates the closed loop liquid which is heated by an 4500W immersion element housed in-line with the water flow. No storage tank.
I was struck by how simple and elegant this solution appeared but heating is not my field and I would love to see any comments that the experts out there can provide. What, if anything am I missing? The owner says that the system is able to keep up with demand and that it operates very efficiently. I asked for consumption data but that was not immediately available.
