I have a customer doing a bathroom re-model and is installing a steam sauna/shower. The plumbing supplier has provided a 10KW generator that seems (IMO) really large. The shower stall is 3'x 5' x 7'-6" high. 2 walls, the floor and ceiling are insulated and 2 walls are glass. I think that he's shooting in the dark. My only concern is the home is served with a 200A main that also feeds a guest house on the premises. I'm in the process now of re-calculating the required service for the entire home. I believe that the 200 is going to be low. Does this heater sound large? 10KW = 34000btu/hr. I don't see how the temperature can be controlled correctly. This seems like enough steam to convert the whole house to a sauna. The home owner has confidence in the supplier although if I have to tell him that we've got to go to a 400A main, something's going to give. The last steam generator that I installed only required a 20A 120V supply. Any sauna experts out there?
