Thermal Snap Disk
I have a thermal snap disk in my coach that works on 12 volts but the little heater does not work. I verified the defective heater by hooking it directly to the 12 volts, bypassing the snap disk. Wi...

A little explanation is in order. It's not an Aqua Hot. I keep my coach in my RV shed at home when not camping. I don't like to blow out my lines after every trip so I just want to keep the temperature in my wet bay above freezing while parked at home. I do have a couple of thermo cubes and am using them with my little 120 volt space heater. Presently I am running a dedicated 30 amp extension cord, from my shed, into my wet bay. My coach is plugged into a separate dedicated 50 amp line.
When deciding to run 120 volt heater instead of the 12 volt, I discovered I don't have a shore powered 120 volt outlet in any of my bays. The one that is there is running on the inverter (that seems unusual to me). I didn't think it would be a good idea to run the heater off the inverter and that's why I ran the 30 amp line into the wet bay. I know I don't need anything that big for the little space heater but it was what I had and am not using the 30 amp for anything anyway.
Now, to the point. I was thinking about wiring a 120 volt outlet (from the 50 amp coach power panel) into the area. Then wire the snap disk into the heater cord. That way I don't have to mess with the extra extension cord every time the temperature gets too cold. If I find a good 12 volt wet bay heater, I may eventually wire it back up. The one that isn't working is the "Back Seat Heater" and they get terrible reviews. Suggestions for a good one are welcome. BTW, I know I have power to the 12 volt line and I believe the snap disk is working fine. Just in case, I did buy another disk yesterday (thanks time2roll for the link). Apparently the snap disk don't care if it's 12 or 120 volts.
Just FYI, the 120 volt heater information. I have three 200 watt space heaters and two 250 watt space heaters. I think one will be enough for the wet bay and I didn't buy that many just for this project.
