Hydronic Heat Freeze Protection

[Fredward]

Just learned this yesterday. Did you know that if you turn on the Webasto system but don't turn on the interior heat exchangers, there is a thermostat in the wet bay that will run the Webasto and circulation pumps only when necessary to keep the bay from freezing? (Temperature is actually adjustable).

Those of you like me in the cold climates may find this useful.

This makes me think of something I haven't thought of before, for those with heated floors, how do you keep it from freezing if your RV is in storage and not being used for the winter? Does the in floor heat have antifreeze flowing through it or is the system actually electric heat wires in the floor?

Country Coaches with heated floors use an electric grid under the tile for heat. Coaches like Entegra use the coolant from the Aqua Hot flowing thru Pex tubing under the floors. Freezing of the coolant is not an issue assuming it is a proper mix. The heat transfer fluid used in Aqua Hot units is really just antifreeze but a safer (GRAS) version.

Fred-

Thanks for the great tip! I was not aware of this and have heated the entire coach a few times to o o keep things from freezing.
