I agree with your point about off = unrestricted. When my LWT went up to 48, it was in the process of raising the IAT from 21.5 to 22.5. The set po...
I don't think so. It takes about an hour or so to heat from mid 30s to 48.5. I would have though any residual peak from the HW would be long gone? B...
