Heated tanks..winter use

[Nicholsfamily05]

Have a quesrion that I have searched around and can't find the answer too.

We have a 2017 Sierra 377Flik, front living room, it has heated tanks but I can't find out if it has heated pipes. When we ordered it we chose every option we could but just no info on the lines.
I've emailed the company but have not gotten a response and I've asked the dealership and they weren't to sure.
An internet search didn't pull to much together. Some trailers I have come across do have it but some of the others only have the tank pads.

I want to use it for the next two months during the week basically as my job has opened up a major OT spot for that period or longer and since I live an hour away after working 16 hrs and having an hour ride there and back doesn't leave much time for sleep. We store our RV at my fathers place that has power and full hookups. I installed them when we lived there.
I could stay in the house but I don't want to bother my father coming in at 11:30 and getting up early each day for weeks on end.

Thanks in advance for the help.

I am actually less concerned about my waste tanks. Certainly have had my fresh water tank freeze and my fresh water lines. Last time I had to use both 12v and 120v of the combo pad to keep the fresh water flowing. Also built a circulating water system to prevent future freeze ups in the fresh water system. Nothing like going -10 with an open belly. I went with mostly 120v heaters as it would have been close to 60 amps at 12v to heat all four tanks. That amperage is not going through one switch.

100% of TANK HEATERS I have ever delt with .......Heat the WASTE TANKS......... keeps them from freezing so you can dump.:):W

NEVER EVER heard of Heated Fresh water tanks...or Lines. (Sewage or other)

12v tank heaters take 10 to 12 amps at 12 volts. Switch is commonly rated 15 amps.

Maybe they use a relay, high amp switch or these are 120 volt.

I installed these pads: www.ultraheat.com

I can't crawl under it. It's a sealed underbelly.
The dealer today said I should have pads on all my tanks. That's what the switch is for in the control panel.
He said as long as the furnace is on it will heat the area where my water lines are ran. Good idea in thinking but like I said I'd hate to just waste all that propane.
Been looking at hearing elements with a fan to feed that area instead of using a constant supple of propane. Electric would be easier.

Can you crawl underneath to see the bottom of the grey water and black water tanks?

You should be able to see the black electric heating pads on each tank if that is what is being used.

We have a single switch for our heated tanks. It turns both black heating pads on - one on the bottom of both the grey water tank and the black water tank.

Yes it is a single 12 volt switch but they stated i have them on all 4 of my tanks.

Hm means I may have some work this spring / summer wrapping some pipe or putting in an electric blower with a heat element down there.

The tank heaters would not be run off of propane, obviously aside from the actual water heater (for the hot water taps). If there's a separate switch for holding or fresh water tank heaters, they'd be electric heating pads of some sort.

If the plumbing is in a heated basement area, that would typically be heated from the propane furnace.

We are going down today to get her ready and I will check around and see about the bay opening.

There is a switch that says tank heaters next to all the other switches but only one.

That's why I was asking because the RV industry does some weird stuff and I wouldn't put it past them to just put the pads in and. It the heat tape.

Check for a heater duct opening. It really just looks like an open hole on the side or top of sewage bay. 😞

Mine had a heater duct opening on the top of the sewage bay out of view. What they did was split the bedroom heat vent duct work and diverted half of it to the sewage bay....that is what they considered heated pipes/tanks. :R

[time2roll]

Do you have a stack of switches for these heaters? No labels?

[DrewE]

I'd be rather surprised if they offered tank heaters but didn't have the plumbing run such that it could be used in freezing weather...otherwise, why bother with tank heaters? (Then again, the RV industry does some things that don't always make sense!)

You might check to see if there is a heater duct into the basement... My camper had a 2" corogated flex line into the basement but no air flow due to internal resistance, so I added a 4" duct from a spare furnace plenum outlet and the flow then was outstanding...
