Heated Tanks?

OK so after I de-winterized we went up to Mt Charleston and started to get snowed on Friday and I started to sweat about freezing pipes----Temps never dropped as much as I thought so it was a non-issue---but what exactly does the heat element on the tanks actually heat? I know that sound ridiculous, but will it keep anything other than the tanks from freezing AND is it fresh, black and grey? How cold can we be out without damaging the plumbing system?
BTW I have a 28ds.....Thanks, Barry

To my knowledge, the waste, gray, and freshwater tanks have an electric heat blanket wrapped around them. The wall switch controls them and a factory default temp control tries to keep them 40 or above. I believe it turns on at about 36 and off at 45.
I have never seen or read of the pipes being protected. Though most are near or above the floor.

For the pipes, i let the faucet drip at night or hook up an air compressor and blow at the lines at 30 psi. You can find posts on how to do this.

In my limited experience the only thing that freaks me out a bit when it gets to freezing is the outside shower. Seems like that would get coldest.

During the spring when we get a couple last minute freezes after I've dewinterized, I'll leave the furnace on and set real low like 45F. This way, the furnace kicks on/off and the ducting that goes through the storage area keeps some of the heat going down there. For the heated tanks, there are pads under both black/grey tanks along with some heated wraps around the valves in the water bay. Also running your hot water heater those nights can help as I'm sure some of the heat stays in the compartment. Propane is cheap insurance on those days. Just my 2 cents. Ours is a 30DS, but same logic applies.

Kansas is right. The hot water tank compartment generates lots of heat. That compartment is supposed to have a panel on it with a round rat hole port behind the door. Most of us promptly remove that panel for access to the bypass knobs but I. Was told by my dealer that the entire bin all the way across to the fresh water fillers conducts heat from the hot water heater. Assuming you occasionally run your hot water to keep the hot water heater running , That heat combined with the pads under the tanks should keep you good.

My first year I carried a mini 60 watt spot light (the type that has a clamp on it) to keep in the water bay where the shower and fresh water connects. Keeping that on at night in the compartment generated more heat. For extended stay in cold climates you can get a heated plug in water hose too. So many accessories so little time........

Year one I had a wireless weather station with an outside Wireless remote temp sensor. I placed that remote in the bin and could tell what the temp was from inside the coach. It provided peace of mind one morning when we woke up in the parking lot of Foxwoods casino in CT and found three inches of snow had fallen overnight!

Now in year three I have started removing these extra items as I don't travel in cold temps for extended periods, they rarely get used.

Thanks all I really appreciate the help----yes I now travel with a portable 60-watt clip on light just in case.

If you have an "Arctic pac" there are heaters on the gray and black tank as well as on the elbows that lead up to the wafer valves in the sewage compartment. Not sure about the fresh water tanks.

Heated Tanks?

One hard lesson I've learned since joining this forum is that wide generalities are often wrong! For that reason, I make the point that the following info. relates to my 2015 Wildcat... may or may not relate to other units. I don't have an Arctic package specified on my build sheet, but I do have a line that says "12V HEATED TANK WARMERS". They don't wrap around the whole tank - at least not the FW tank. I took this picture after shoring up my FW tank to keep it from being jettisoned on our way to Goshen last summer. You can see that the FW tank 'warmer' pad (dark rectangle) is pretty small. Is it large enough to be effective? Dunno... haven't used my tank heaters.
