Atwood Furnace Durability

I am a recent full time boondocker and have concerns about the reliability of the Atwood Hydro furnace. At 45 degrees it seems fime, but down in the 30's I feel like I'm stressing the system. When it runs 6 or 7 times an hour is that too much?

Note: When I have city power I use an auxiliary space heater. I've looked at the portable "Mr Heater"s, but they seem too big in size and heat capacity for a 19' Bambi Safari. Thanks

I've run mine in -10 F. It runs continuously for a couple hours until the trailer warms up in weather like that. I don't worry about "stressing" it.

They don't last forever -- there's cumulative deterioration of the burner and heat exchanger with every hour of operations, just like a home furnace -- but they do last a long time. Years, decades in many cases.

Cycling on and off is not a problem for your furnace. It is how the temperature is and was meant to be controlled. You do not need to worry about it.

Many thinks. It will be 26 degrees in Lone Pine, CA tomorrow - I'll sleep better now.

We have used the furnace in our 2002 19' Bambi for many years in temperatures ranging as low as 9 F. The furnace has needed a couple of new control boards and sail switches, but not as a result of heavy use.

As you stated that you are a "full time boondocker", I would think that the power demands the furnace makes on your batteries/solar/generator system would be more important than wearing out the furnace. If you haven't checked into catalytic heaters, give them a look.

I have a 160 watt Zamp solar setup, which has had no problem restoring full batteries so far (but I've only been in the desert sun since I bot it), and I thought the Mr Heater "Portable" was to big - but I should at least get the "Little Buddy" for backup (and rainy says).

Depending upon your battery bank, a couple of cold nights with the furnace running like you describe, and two cloudy days, you'll probably need that backup.
