QUESTION:We boondocked it this weekend out in the tweeds. We had a fabulous time in
the mountains. We stayed at a free camp-ground and we basically owned the
entire area. No-one else there except our group of three RVs was there..
One thing that was very apparent to me is how hard my furnace works. It was
on more then off during the cold nights. One of the others that came along
had a larger furnace and his was on only for short periods (often on but
would bring the RV to temp *much* quicker.. My thought is, a better furnace
will save battery power as the blower, basically, is constantly running on
mine when it's cold outside..
Quite honestly, my last RV had a much better furnace. It was very quiet and
the heat coming out of the vents was hot, not just warm. In my newer RV the
furnace does not seem as robust and the vent heat seems only Luke warm, not
very warm to the touch thus the blower has to run for ever to heat the
inside.. Also, my current furnace is much louder; it almost sounds like a
hair dryer. I believe my last RV had a squirrel cage blower which was much,
much quieter..
It boils down to this: Is a upgrade to a higher end furnace common? Can
someone who has done this recommend a retrofit and tell me some specifics?
ANSWER: It may not be the furnace, but rather the adjustment on the
thermostat. That is to say it may be set too wide, your RV cools off
more, then the heat runs longer and takes it up to high. There have been
several posts here over the years on how to adjust this (I don't recall
the exacts, so I'm not going to try)
An option might be a cat heater. The one we had on the old RV worked
very well. It was thermostatically controlled and run as needed, buy
didn't put the load on the battery that the "real' furnace does. It was
an Olympic 6100ET (the ET part means it's electronic, they also have
manual ones)
