IF you still have the Newmar. Newmar back then used the Furnace as a heat vehicle for the Water Bay/Tank compartment. They used a extra 12 volt fan connected to the furnace duct to blow hot air to the Water bay. I have never seen a Newmar(motorized and not a King or London Aire)(1993 to 2009) use any Heated Pads for the water tank system. Are you positive they were not added after market? If you think you have them, where is the wall switch to activate those heaters? Doug

This is true, normally the basement heater will take care of the tanks. but when you don't run the furness, you plug in and turn on the pads.

and no, they are not an after market, they came as an option when the coach was bought.

Yes we have a wall switch in the bathroom to turn them on or off. it has a red glow light when they are on. I check them now and then.
I've never used them, we are normally not on the road in extreme cold weather, and when it is really cold we are home and the tanks are empty and pink added, and the water system is blown out.

I find that odd. I double checked the standards and options for your year model and it did not list ANY optional tank heaters. Doug

Our coach was a custom build for the first owners, They could have asked for the heaters to be part of the build.

I understand that. BUT, you have fallen for one of the BIGGEST mistakes RV owners make. YOU did NOT buy the unit new. So, when you post items about your RV, you should NEVER assume that what YOU have was standard or came with the unit new. I, on the other hand, serviced(we sold) Newmar from 1993 until 2008, and we sold a boat load of MADP especially from 1999 until about 2005. So, when you posted that, I was very surprised as I KNEW Newmar did not install 120 or 12 volt heat Pads on MADP back then. That is why I looked up the original Standards/Options Sheet for your Year. Now, Back them , Newmar would option off the sheet items for order if it fell within installation parameters. But, It IS possible that your 120 system was added by the selling dealer as Newmar would not have added it. Off the sheet options by Newmar back then would NOT include parts that Newmar did NOT have in stock for installation on the production line. Doug

I've known our coach from day 1, I helped the first owners buy it and pick it up. I know what has been done to it after that. So I do know that the tanks have never been worked on or anything added.
the heat pads were placed in the coach as built.
