Your crossover valve is open.

No it's closed. I would think the electric would be enough to keep up then gas it it couldn't. Once water runs cold the gas comes on then heats water right up within 5 mins. Guess my old trailer had a higher wattage heater. Going to call dealer on Tuesday.

You may want to check the crossover valve again or perhaps if you have an outdoor shower, that the taps are shut off, and not just turned off at the handheld shower wand.

Either one allows cold water to be drawn into the hot water line, thus you do not have hot water for long until the cold water mixing in lowers the temp. This is a common thing when people state they don't have hot water for very long.

Posts #1 and #3 in the link I provided above may help. It's easy to mistake the position of the crossover valve, since the line it's on is vertical.

Turn the electeic gas and water off. Drain the HW tank. Flush it out, turn on water, go inside turn on the hot side of a faucet. Wait for a steady stream of water. Turn on electeic and gas. Wait 30 minutes and see what happens. I suspect you have a big air bubble in the HW tank. Yes, you need some dead air space, but too much and what your describing can happen.

We still think you probably have partially open bypass valve.
In rare cases folks have found the valve defective and the handle wasn't
turning the valve correctly.

IF you open the outside metal hatch at your water heater the brand
and model will be found inside. Wattage of heater is most likely 1400-1500
watts but we can't be sure unless you provide make and model of WH.

We tried everything with ours not heating on electric. Took it to the camper hospital this weekend (back to dealer) for it to be checked out.
