I have received several emails concerning the heating system and how it
is tied into the cooling system. I understand that the coaches supplied
with preheat lines would be easy to tie into. The hot water simply runs
through the water heater to the fan coil. Since I dont have this
system, I dont know how it runs and will check out the manuals.
The hot water lines running to the original heater in the dash would
probably be a good place to look. It was raining too hard to look
yesterday. Maybe later tonight.
I am really excited about this project and think that an A/C and heater
in the rear is a good addition. I dont want to run the propane furnace
on the road and the wife and kids are always cold or hot. This way I
can let them set it. I also like the dual use of the thermostat. Saves
at least 3 oz of weight. By the way the fancoil only weighs about 10
lbs. The added coolant and hose will add to the weight but it is weight
well spent.
I purchased a 30,000 btu fancoil, heat only, single speed (8-1/2 x 8-1/2
x 8 approx) on Ebay for about $38 including shipping (I will look it up)
before I found the heat/AC unit. It is available to anyone who wants it
at my cost plus shipping. For anyone who doesnt need A/C (someone from
Vancouver, for example), it would put out a lot of heat.
