I believe raising the efficiency of a trailer furnace from 75% to 90% is a balancing act between initial cost and the cost of operation. It appears that the majority of RV owners are not fulltiming and are mainly camping in moderate weather. Saving 15% on fuel costs is relative to the amount of fuel being consumed. If one consumes only a couple of tanks of propane a year , ,is a 15 % fuel savings that significant ?
I agree. I would prefer higher efficiency, but it is not an important factor for typical RV use.
Gotta agree and taking the unit up to 90% plus would also open up the acidic condensate issue. Dumping it out on the ground might be unpopular. :nonono:
Yes, this is one of the issues with condensing furnaces in residential use, but I don't know why the condensate couldn't just go in the grey wastewater tank.
It's my impression the most desired upgrade would be a whisper quiet fan.
I agree.
The next for me would be using separate motors on the draft inducer and main blower (like every home furnace), so neither would run unnecessarily.
All Escapes are getting the new Atwood; only the 21's present location has to be changed.
True - Reace explained this early on.
.....especially at people talking about everything else except the issue with the 21's furnace being relocated.
I'm not sure what the issue here might be. If only the facts reported in the original post are allowed to be discussed, there should be no discussion of appearance at all, even the 21', because Bob only mentioned size and the consequence on drawers of the move.
The only thing I noticed being discussed other than the differences in the old and new furnaces, and the effect on installation in Escape trailers, was other properties of furnaces. Given that Bob's original post mentioned "other suitable replacements of the same size", this doesn't seem unreasonable to me.
No other model is affected by this new heater and as such those with 17/19 & 5.0 TA don't have to consider the domino effect on aesthetics or storage.
I don't think that's quite true. The face of the furnace (which some people seem to find unattractive) will still look different in every model; the proportions are different so every model's cabinets will change at least slightly. I don't understand why the reportedly unattractive grill being visible from the door of the 21' would be relevant, yet the same grill being visible from the door of every other model would be irrelevant.
