Does anyone have any experience with this? Can the switch be wired into it's own circuit at the inverter so the system will work while traveling and or plugged into shore power? Thanx in advance.
In my RV, the tanks are located within a heated basement compartment. The furnace has a 2" air duct to the area near the tanks.
My guess is the tank heaters need to go below the tanks, and in my RV that would require lifting them about 1/2". The easiest way I can think of would be to put in slats about 1/2" thick to raise the tank slightly without disconnecting all the lines. However it might dislodge the toilet tank fitting.
I am glad that I have heat from the furnace. A 100 watt heater will only put out 340 Btu's per hour and take out about 10 amp hours from the battery through the inverter - so a 100 AH battery would be discharged overnight for each heater that is installed.
It would be much easier to run a water line from the water heater back to the fresh water tank, so you could take 6 gallons from the hot water tank at 140F to heat the 60 gallon water in the tank that was 40F to 55F. That would allow the tank to not freeze overnight without depleting the battery, and add 6,000 Btu's to the water tank in 5 minutes.

uhmm Thanks for the info but I was refering to the heated pads that stick on the bottom of the holding tanks......very low current which alows you to run them on 12v while not plugged in....but charging from the tv.
I've got three of them on my rig. They are wired off the coach battery with three auto-reset c/b's and then through switches near the main electric panel. The pads have built in 34 degree thermo switches so they only consume battery amps when it is needed.
