Water Heater

Hi,

I generally do not use propane to run the water heater.

If you leave it on, and draw no water, the unit will cycle on for about 15 minutes every four hours, once the water is hot (mine is a 10 gallon US).

So, if I'm plugged in at a friends home, I'll turn the water heater on first thing in the morning. By the time I've finished breakfast there is ample warm water to do the dishes. Then I have a shower. Then the heater is turned off. That leaves enough water to do the dishes at lunch and supper as well as for hand washing.

At a campground where power is included in the lot rental, I'm a bit lazy and just leave the heater on.

Because I want full wattage from electric heating devices, I find myself using an autoformer a lot.

In my TT even when plugged in I leave it off unless needed. I think it's probably because I mostly boondock and the sight of an illuminated switch being left on bothers me.

If on 50 amp we always use electric and leave it on. And do not use propane unless the weather (and incoming water) is cold. Then we run both electric and propane for faster recovery rate.

If on 30 amp we use propane and not electric to reduce chance of tripping the 30 amp breaker.

If we have 50 amps available, on. If less on as needed.

I thought I responded to this already but don't see the post.
We always use propane to heat the water and use the electric as a backup.
I have had to replace much of the electric system in our water heater and don't want to subject it to every day use.

Always on...

On electric, we leave it on.

I leave it on.

leave it on, it,ll shut itself off as the temp rises to its set point.

if plugged in the WH is on 24/7.
