The ending of summer has arrived and with it comes the urgency to get ready for winter. Having a pool during the winter makes for much trouble. You almost always need to drain it, and make it winter ready. To update your pool and keep it open this winter, why not install a raypak pool heater to warm the water during those cool times? I think it's cool to drive by a pool in the winter and see the steam rising from the water in the crisp air.
