    Heater Inside the Jandy Power Center

    Hello. I will be closing our new pool for the first time and have a question regarding the best way to protect our costly Jandy Purelink Power Center over the winter. I am an engineer in the electrical construction industry and it is common practice to install a light bulb inside electrical equipment enclosures prior to them being energized. The heat from the bulb keeps the inside of the enclosure warm and dry.

    I am considering using a small light bulb (say 25 watts) inside of the enclosure to keep it dry over the winter months. Has anyone done this? Does anyone have any other suggestions to protect the Power Center?

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    I read this when you first posted it and was hoping someone would come along with a great idea. Apparently not!

    I too being a E² have experience with heating enclosures. We never use light bulbs but instead use purpose built enclosure heaters. Go to and you'll find some inexpensive ones with thermostats
