Wim lives in Massachuesttes and love to swim. Unfortunatly, the swimming season is short, and his pool is shaded most of the day. We decided to build a Solar Pool Heater. We found some 4x8 solar collectors (hot water panels) on craigslist. They are new-old stock, and sold cheap. So cheap in fact, that it was cheaper to buy these panels then to make our own collectors from scratch.
