Atwood Heat Exchanger Capacity

[john yurtinus]

I've been searching and searching and can't find anything indicating the heating capacity (BTUs or whatever) of the heat exchanger in any of these
tanks (Atwood, OEM, or the replacements at Applied).

Does anybody know a rough order of magnitude capacity on these exchangers? Or how long it takes to heat a tank of water with engine heat?

15 or 20 minutes driving heats ours

Your 6 gal Atwood is 8,800 BTU

It's 8800 BTU/hr from the propane burner, I'm trying to figure what the engine heat exchanger does. If it's 15 to 20 minutes, that's a bit faster than
the propane burner - maybe safe to say somewhere north of 10kbtu/hr but not 20k.

So to come clean on my ulterior motive behind this question, I'm contemplating if it's feasible to use an RV water heater to drive a hydronic heating
system. There are systems from Ardi and others that couple a giant boiler with a smaller hot water tank, but they cost an arm and six legs. It sounds
like the exchanger in the cheaper RV/Marine heaters can pull enough heat from the tank, though the burner in the heater wouldn't be able to keep up,
and I suspect it'd struggle with the high duty cycle.

I don't like the hydronic setup = there isn't any place you can stand in a blast of hot air when you come in from the cold.

Johnny,

Sound like you, like me, grew up backing up to an open fireplace!

Hah! I'm the opposite - I hate how a forced air furnace dries everything out.

How fast does the waterheater get hot?? Depends on how agressive your right foot is.

I keep forgetting Ken H's replies show as mail as well as here - and get answered as mail
We were uptown - we had a fireplace and a floor furnace. Stand on the grate in the morning to dress.
