Water Tank Temp

[DWallinger]

I am taking possession of a new Galleria that has the polar package that is supposed to work down to 5 degrees. While the fresh water tank has a heating pad, it's located beneath the van floor. I'd like to add a tank internal water temperature probe that would attach to a thermometer gauge with an alarm that would be triggered when the water temp is just above freezing. I'd prefer an internal probe but would settle for an external "adhesive" sensor. I've searched Google and Amazon without success. Any suggestions?

Depending on the Galleria model, the grey tank is under the floor, too.

Check out the Coachmen Galleria Class B RV Facebook Group for lots of folks with lots of experience providing lots of good information and support.

That is easy.

Put it on the water heater. That will tell you it doesn’t need to be on. I use it to set water temp so I don’t need to waste water setting the temp. 103F works in my B, 93F works in my C

Not so easy. On the Coachmen Galleria the Truma Combi (furnace and hot water heater combined)
is used. It is inside the coach. His water tank is outside and under the coach. He wants to protect it from freezing. 103F and/or 93F have no use for that purpose.

I would probably simply insert a tee fitting in the line between the tank and the pump, as near as possible to the tank. Then just epoxy the aquarium sensor into the third branch of the tee so that it is immersed in the water coming from the tank. The temperature in the pipe is more relevant than that of the tank anyway, since the pipes will freeze long before the tank.

Just strap it to the line under insulation.
