I ask because the boxes with the sewer dump and fill valves is heated, but I donít see how the fresh water tank can be heated given itís location.
Any input appreciated. Thanks.
Your fresh, gray and black tanks can also have heat pads installed beneath the tanks. These are typically pretty small (less than 1 s.f.) and most of them run on 120V so you need shore power or genny running.
The heated wet bay is heated to keep your stuff from freezing when the RV is in use but not much help when stored as you're unlikely to run the furnace or AquaHot unit unless occupied.
When to worry? That depends on your comfort level with the way you're using your coach, where you're located and how long the ambient temps get below 32F.
