water heater question

Yes, you need water in the rigs system.
If equipped make sure the winterizing water heater is on to allow water to enter the water heater.
You would not need to light the water heater in advance of a trip. You can light it when you get to your location. Takes 15-20 minutes to heat the water.

Why do you want to heat hot water? I will never understand that

After you've filled your fresh water tank & turned the pump on, the hot water heater tank fills automatically, which actually allows for more water in your fresh water tank afterwards.

You need to open water faucet valves to get the water to fill the water heater and the lines. It will not fill without turning on faucets to purge the air out.

Well, given that it's constantly and slowly cooling off, it does need to be heated up from hot-but-not-hot-enough back to hot-enough from time to time.

Make sense? ;)

The hot water heater police strike again.

It's a blending of "water heater" and "hot water tank."

What I will never understand is ridiculous replies such as this. Seriously? I mean, really?

Are you sure you have to light the water heater pilot for the other gas appliances to work?

That would be unusual. Even when the appliances were all manual control, each piece (range, furnace, fridge) had its own pilot light. Most often today, only the water heater and oven have pilots, everything else is spark ignition.

But yes, you do need to have water in the water heater if you are going to ignite it. Otherwise it can overheat, as the controls and protective devices are designed to measure water temperature.

The OP is new.
I think what he is saying is that the LP system is manual. He has a pilot for the water heater, refer and furnace run off propane.
Same as what you wrote in second paragraph, tatest
