6 gal water heater with heat exchanger?

I am getting ready to order a new water heater for my MH. I noticed that you can get a 6 gal Atwood that appears to be the same size and shape as the original that has a heat exchanger that circulates engine coolant thru the water heater and heats the water as you drive. Seems kike a good idea. When you arrive at your destination you have hot water. Does any one have any first hand experience with such a system? Does the engine water pump have sufficient flow to operate the system? Are there other drawbacks?

Mine works well. It's hooked in line (or series) with the heater. No additional load on the engine water pump. I'm not sure if there is a bypas valve to keep the water temp from getting too hot.

I wish mine had and electric element also. Cheaper (free) and quieter than propane.

When I replaced my water heater a couple yrs back, I guess I got the "fancy" Atwood. It is propane, electric and it has the engine coolant heating tube. The reason I got this one is that it also has the electronic start. Propane or electric heat up the water fairly quickly...I turn both on when I'm in a really big hurry!

This is just my personal feeling, but here goes...I have no plan to ever hook up the engine coolant tube. It is just one less water leak issue to deal with and I would never want to see a coolant leak in the galley and spread from there. It was a lot of work installing laminate flooring and carpet! . Again, just my personal preference.

Also was going to say, having the electric is nice. At the "ranch" property, we have full hookups and other then our yearly assessment payment, we only pay a small extra fee for electricity if we want to leave the RV plugged in while not there. So it's nice to not be using the propane up.

We do have a propane "filling station" at the property and basically sell it at coat to owners. Better then a round trip into town and back...80 miles. I'm rolling my eyes to myself at the moment though...in a good polite way...there are only two maintenance guys that I ask when I get propane. The others don't get it that the propane tank on the MH is not removable. They always say to just drop of my tanks and come back later. Even after the explanation, there is still a puzzled look on their faces. And of course it's a major pain to disconnect and drive over to the propane tank. Again I really like having the electric element!

Gosman,

You're in the Motorhome section of AirForum. Don't know if you'll get too many responses here to your question.

Hi,

Love the heat exchanger in mine. Dadstoy has pointed out the biggest concern with having the heat exchanger. In mine, there's about 70 feet of heater hose that would have to be replaced when it's time for replacement. I've camped a few times before realizing that I had heat exchanger. It's really nice NOT to have to turn on hot water heater until next day at camp.

I will say this, I do plan on converting mine to also have 120v heater element installed.

And yes, I do plan on keeping aux heater and heat exchanger on hot water heater. Hoping for an Alaska trip next summer, have a feeling, I may need aux heater once I get further north......

The heat exchanger in my now gone '83, 310 worked as advertised, made hot water while you had the engine running. Very hot water in fact, almost dangerously hot. I didn't consider it a great asset though, propane works well for me.

My former Airstreams had propane only water heaters, the new one has electric and propane. I really like having that choice - but having propane only wasn't a real problem. I do live in Virginia where winter normally lasts 5-8 weeks, but I can turn off the water heater and have at least warm water for 12 to 15 hours!

Plus, with propane six gallons will heat within 10 minutes on propane, 15 to 20 minutes. Both should be seven minutes or less. Seems like it's just one more thing to break... and solve something that isn't really a problem.

I bought the water heater with all three sources of heat. I intend to hook up the heat exchanger. I am just finishing a major floor repair, should install the waterheater in a week or so. Crazeevw; what kind of hose did they use to supply antifreeze to the heat exchanger?

So glad to find this thread. Just completed installing a new Atwood water heater.
It is gas , electric, and engine heated.
Surprising to see that the pipe from the engine cooling water on the heater is just welded to the outside of the tank and heats with heat transfer thru the skin of the tank.

My challenge is the electric supply to the heater. I pick up power for the heater at the main power box. Just tied into an existing breaker there. But the heater is too large a draw and keeps flipping it off.

Has anyone found a way to add a breaker into the main electrical box, its so crowded I'm not sure how to make one fit. Please post pics if you have made this happen.

Cheers Richard
