As I read through this
thread on radiant flooring, a couple things come to mind. One is, no
manifold would be required, since the size of the floor is so small.
Typically, a manifold is required for square footage over 250 sq ft. The
nature of radiant heat is a very nice, even temperature (at 110 or so degrees),
but has slow recovery (doesn't react very fast). Electrical needs (or
propane needs) to run it would be pretty high, so boondocking would be difficult
for any length of time. But something that would be really cool, which
I've installed in houses, is a chiller system, in which cold (refrigerated)
water cools the floor surface. If someone could rig up a refrigerator
condensing coil that is propane fired, that would be large enough to cool around
200 sq ft, then you've really got something. So if you're going to do
radiant floor heating, why not radiant floor cooling at the same
time?
There is a company that makes in-line,
propane-fired hot water heaters. Something like that might cut down on the
time it takes to heat up a floor. Otherwise, you'll have to drive down the
road with the heat turned on for several hours, so the coach will be warm when
you reach your stopping point.
