With winter here and us still in the cold north country the protection of our coach’s water and sewer system is critical. We don’t want to deal with broken pipes, hoses and tanks costing hundreds, if not thousands of dollars to repair.
Our coach came with a Wet Bay heating system … a thermostatically controlled electric (DC) space heater. But, that 12v heater gave up the ghost a long time ago. We never really worried about it, because we winterized by moving south to warmer climate for the last five winters. But this year business obligations kept us in the north far later than we’ve ever stayed before since full-timing.
How I Replaced Our RV Wet Bay Heater
So, to help deal with the climatic conditions I had to come up with a way to do what the coach’s system used to do. Sure, I could have replaced that RV Wet Bay Heater with another one. But they are expensive and I found a cheaper, better solution. Here it is:
You need four things:
- An EasyHeat or other thermostatically controlled outlet. These come on when the temperature they are subjected to reaches 38°F and shut off when the temp hits 50°F. Thus it will cycle the space heater on and off as demand requires.
- A wireless Indoor/Outdoor Thermometer. We installed the main unit inside to track the temperature in the rear area of our coach. I hung the wireless remote sensor in the wet bay to monitor the temp inside the compartment. This was to make sure the heater was working.
- A compact (personal) 110v electric space heater. These little heaters draw just a couple of amps and easily heat up a small space, such as a wet bay or a bathroom inside the RV.
- Power Source: I sourced the power from an outlet inside our rear engine compartment that is for the engine block heater. It’s on its own 20 amp circuit, so I can deactivate it if I need to from inside at the circuit breaker panel. You could plug your extension cord directly into the power pedestal if there is a 15/20 amp outlet available.
Whether you’re a diehard gotta’ stay in the cold north RVer or are somewhere in the south enduring an unseasonable cold snap, this setup could help you. Stay warm, stay safe and Happy RVing!
