If you are new to the area and have solar assisted water heating for pool, spa or other......remember that when temperatures go below 39 degrees the roof panels are subect to freezing and damage. The panels are very thin and exposed high up subject to wind chill effects.

Your manufacturer should have guidelines for turning off the system and by-passing the water circulation to the panels.

WHy 39 degrees? That is what our manufacturer recommends as a cautious temperature to use. And 39 degrees with a slight breeze can easily be down to or below freezing.

If your pool system has an automatic controller it is most likely set to auto cycle the pumps during freezing temperture periods. Check your settings to be sure this feature is in fact enabled. If you do not have a controller on your system turn on all pumps during below freezing temperatures.

Wind chill factors are based on temperature loss on the human face at varying temperatures and climatic conditions like wind. There is a school of thought that suggests inanimate objects like car radiators and such are only affected by the base temperature. Prudent freeze prevention planning would suggest planning on the wind chill temperatures.

Any other winterizing tips (for pools, spas, faucets and plants, etc) used by others are appreciated.
