The heated floors work just fine, but they are slow to get hot. On my Anthem, it might take 24 hours (or more)nfor them to get warm enough that I didn't need any other form of heat. However, it is going to take the diesel burner of the AquaHot to effectively warm or keep the floors warm. So, if you are traveling or on the move, you have to keep the diesel heat going all the time.
The floor heat is not electric.... it is produced by circulating warm fluid. If you see a coach being built, pex is run in flowing zig zag pattern through the floor joists. The a whiole, there are cold spots but eventually the floor warms evenly.
If we stayed in the same place for longer times I would use the floor heat more, but when we travel, we rarely stay more than a week anywhere and I find that the diesel fired warm water radiators with fans blowing over them the better option.
