Hi,
I live on the coast of Maine and will be putting in an above ground
pool (probably 18 x 30) and it will reside under a 30 x 48 greenhouse,
about 12 feet at the peak. I have some ideas floating around in my
head about making an inexpensive solar heating device using black
plastic pipe on the inside of the greenhouse frame, but before I start
pestering you guys (and gals) about questions that arise, I was
wondering if you could point me in the direction of a good book or
source so that I can do some pertinent calculations to see if this is
feasible or not. I'm handy with tools, but have never tried to
calculate what it takes to heat such a large amount of water using
solar. While super high efficiency would be great, ie a commercial
unit, I'd much rather go inexpensive and simple, even if it didn't
heat as much or as quickly. Any help would be greatly appreciated.

Hi Pat,
You might take a look here:
http://www.builditsolar.com/Projects/PoolHeating/pool_heating.htm
The HP articles on pool heating basics provide some good basic info on
building a pool heating system.
There are a couple of out of the ordinary concepts for solar pool
collectors at the bottom of the page.
The one from Rutgers might be integrated into a greenhouse structure,
and would certainly be cheap.
The efficiencies that were measured on the collectors they built were
good.
