The problem that I see with the tankless is not 39 but 32 39 is a safety buffer.. They hold a small amount of water... and can be damaged if it freezes.
now an Atwood or Suburban tank type. if it's 10 below zero the burner keeps the water HOT, and liquid (so long as it is turned on) and contrary to the myth hot water does not freeze at all (it has to get cold first) (The myth is it freezes faster.. NO IT DOES NOT) so so long as the water heater is operating it can not freeze. but the Tankless.. Can so you need to keep them above freezing.
