Tankless water heater

[jbranontn]

Just returned from maiden trip in our 2011Wildcat 5th wheel 302RLS. I have a question about my tankless water heater. First, after de-winterizing and sanitizing the fresh water tank, i filled it back up. I then went out and flipped switch on outside inside water heater panel. Is there anything else i needed to do before getting hot water? I ask because when turned on hot water. The water heater started making a loud noise when it kicked on. Is it normal to be so loud? I immediately cut it off because wasn't sure i had done everything correctly.

I have 2 tankless, LP, water heaters in my home, but not in my RV. Neither makes any noise except for the LP burner. Is yours electric or gas? I believe electric heaters have expansion noises associated with them, but am not sure. Be a little more explicit with your post.

My wife and I are seriously looking into RVing 5th wheel toy hauler and truck, the tankless water heater was or is a question I have, are they really worth the effort to install into an rv?

In my opinion for Boondocking or dry camping no because you tend to use more water. but if you stay in full service campgrounds than they are ok I have a 10 gallon gas/electric on mine and it is more than enough for us and believe me my wife uses alot of hot water.

As a stationary fulltimer, I can definitely see the pros to having a tankless water heater...Could do laundry, take long showers in the cold, winter mornings, run dishwasher often, fill up our hot tub inside our unit. Okay that last one is a pipe dream.

If our 12 gallon Suburban ever goes out, I might just go the tankless way.

Do they provide instant hot water? If they do, I would think that in a boondocking situation, less water would be used with one because there is no waisting that 1/2 gallon of water waiting for the hot to show up in the shower or either of the sinks.

I have had a tankless in a previous home and it was very good. In the RV I like the fact that I don't have to use my propane when hooked up to power. We have never had an issue with lack of hot water and we have a clothes washer.

dmorse68 =They DO NOT provide instant hot water at the faucet. Nothing does. The water in the line between heater of any sort and faucet has to come out before hot can get there. Unless you plumb in a recirculating pump. That's fairly easy in a S&B but not so much in an rv.
I also would rather use the parks electricity and not my propane. Good luck on your choice.

Makes sense. Thank you for that.
