A new two-stage furnace?

Atwood is no longer producing the two stage furnaces. The RV manufacturers didn't want to spend the extra $, and chose instead to continue with what they have been using. I have contacted Stag, a supplier and they have some and now I am on the hunt for an RV dealer in Montana or Wyoming, to see what the actual costs would be. ( I am off to Mt and Wy in the next couple weeks, for three weeks.)

If anyone wants to suggest a good service centre in either Mt or Wy., I am all eyes...

They are excellent. If the temp is way off where you have it set it will come on on high speed until it is within a couple degrees of where you have it set. Then it will drop to half speed and half burn. Quieter than the hydronic heat systems. Constant even quiet heat. . An excellent drop in replacement for other Atwood furnaces. I've sold a few RV's with them and when my Atwoods die I'll replace them with these.

Good luck.

Gary, I think Golden's point is that he would rather have a furnace come on full force with maximum heat output for a shorter period of time, thus reducing the draw on his battery as the fan comes on. His thinking, I believe, is that a lower stage would need to cycle more often.

Yeah, Golden..all mine is boondocking too..never campgrounds, although for the next three weeks, that is going to change, anyway..back to the furnace...so, you don't think that a two stage would keep your unit warm? I am presuming that the temp would fall back, but perhaps not rapidly? I gotta call Atwood.

The two stage furnace was std eqpt in my former Lance 981Max TC. I loved it and wish I had it in this TT.

I do a lot of boondocking, and as such most of the time that the furnace is running is using precious battery power. And it is noisy. I would rather have a higher heat output for a very few minutes, then shut it off.

When not boondocking, I am in a campground with hookups, and then use a electric heater, and don't hear that fan at all!

Also when boondocking, my Olympic 6000 Btu catalytic heater is on if it is below 45F outside, and I don't cycle the furnace much, until below 25F outside.

So the two stage will not do me any good at all.
