Re: Air Conditioning & Heating
We have an old suburban in our RV. It heats good (22 ft Class C). These furnaces are notorious for sucking batteries dry over night when boondocking and being very inefficient when it comes to propane use. We tend to use electric space heaters but we are either paying for metered electric or its included in our site rental. We will use a hydronic system paired up with the old rear heat exchanger ducted under the bus. We will supplement that with a little LP blue Flame unit in our fireplace mantle. David says I was designing a heating system worthy of spending snowy, freezing winters in the mountains... we don't plan on "doing" snow anymore. We will head to TX where it's not cold for long periods of time and snow rarely happens.
We also have an RV rooftop AC unit (Coleman TSR 13,500 BTUs, also old... it can be powered with our 2.5KW genset... barely). It keeps up in 100+ temps. Doesn't freeze us out but keeps up. RV AC units are also very inefficient when it comes to power usage and limited on the BTUs. They are 110VAC so I can't really see the advantage of using an RV rooftop over a 100VAC home style AC unit if you can use one. And I dislike the AC unit "piddling" water all over the roof... it invariable dribbles on me somehow. We plan on installing a window unit under the bus and ducting it. The AC unit then can "piddle" water to it's heart's content underneath the bus. I know in NM, I will never step into a puddle from it.... the ground here just sucks water up like it never happened (rain storms are interesting out here... puddles tend to only last 5 or 10 minutes). I like the idea that if my AC unit craps out, Then all I have to do is stop at the local Wally World and grab one off the shelf and pop it in. Also I don't want to put any more holes or other stuff up on the roof than I absolutely have to.
