Water heater update

New tank heater installed, fit and finish looks really nice. Did have concerns when it wasn't clear where the switches would be, original thought was outside with the unit. Our suggestion was above the unit in the closet, not ideal but certainly better than heading outside to turn it.
Was thrilled to see that they managed to exchange the old controls with the new in the bathroom. Very nicely done!!
Also managed to sell the old one to a plumber who explained that he no longer installs tankless water heaters because the vast majority he needs to remove and replace. His take is only a small percentage of the population wants/needs hot water for a long duration, where these things excel. Most of us are repeated start stop users where tank heaters reign supreme.
We fill our fresh tank and sit for 3-4 days, no additional water supply or septic until we leave, a tankless will never excel when water is carefully used to last the duration.
Looking forward to warmer temperatures and hot water.

Nice! You'll be glad you made the change. Tankless is a nice concept but doesn't work for dry camping.

Unknown switch

I have a black switch in the bathroom to the left of the thermostat for the water heater. I have a 35UN. Anyone remember what it is for?

Fireman - in my 2015 35UN that switch turns on the EFE. (Emergency Fart Evacuator) The ceiling mounted fan above toilet.

If fan does not come on when you flip the switch - look up at fan, see the black rocker switch in corner of frame, flip this rocker switch and the wall switch should now operate the fan. Leave the rocker switch in on position and use wall switch for fan control.

The fan also does a good job of removing shower humidity too!

Also made the swap

Our dealer swapped out our Girard tankless for a Suburban 6-gallon (SW46DE). It fit into the existing opening without cutting and the LP on/off control replaced the old Girard control knob in the bathroom.

We just returned from our first trip with it. The first six nights were off the grid. The propane burner needed about 20-22 minutes to heat the tank completely. Then we could take two, back-to-back showers without the LP burner ever reigniting.

After those nights boondocking, we stayed three days in a state park with 30 amp service. As soon as I hooked up, I turned on the electric element and had plenty of hot water at any time.

The fridge and water heater together used very little propane. The LP gage was slightly above 5/8 when we left home and slightly below 5/8 when we returned.

I would not return to a tankless water heater --- period. It was the first time in 20 months of ownership (82 nights camping) that we've had no problems, frustrations or hiccups with hot water.

I just don't see the reason for a tankless water heater EVER. Why would you want to have to use your propane for hot water when you are hooked up at a campground to the park's electricity which you have already paid for? Yes, I do boondock some and starting tomorrow I will be for 5 days at Talladega. My propane will work fine and then I'm back to electricity which is already paid for. I did just fill up one empty propane tank so I'm good to go.

Something for everyone.

We do not plan to boondock but once every blue moon. I for one really like the tankless water heater!

I have not used it using the on board water pump, but when hooked to city water it is fantastic IMO. If I take a 15 minute shower no big deal, wife comes behind me and takes another 15 minute shower shaving her legs then the grand child come in for another 15 minutes. We then wash dishes from breakfast and we have nice hot water the entire time.

If three more people wanted to shower no problem, the hot water keeps coming.

If water is being used elsewhere in the coach at the same time the water temp will vary in the shower, only negative I've seen. It does take a little time to get hot but so does our home, I guess I'm used to it.

We just got back from three nights at an RV resort, it was six showers, two nights cooking on the grill (I hook directly to the on board propane to grill), cooled the frig before the trip on propane, washed dishes etc. and I used less then 2 gallons of propane. *I* do not consider that an expense, I actually thought that was very good.

Don't get me wrong, for boondocking I can see where the tank heaters may be a benefit, for me though I'll stick with tankless.

Flame suit on

truma aqua-go


did you ever look into the Truma Aqua-Go
supposedly has Constant, Instant, hot water..

Truma AquaGo® provides instant hot water while on the road

from rvforum:
I have a few friends in Europe who have used Truma products and they say they are excellent. The little I have learned about this particular design is that it should work exactly as advertised. Have any of you heard or read anything about it yet? I first saw it in RV-PRO magazine. They will be rolling out to dealers and manufacturers this spring and summer.
