Check em out guys. I used to work for a company that carried their products and I must admit, they are pretty cool.
I have the power planner 1 series on my fridge and freezer. Reduced our hydro bill by 30 bucks a month, the settings on the fridge and freezer have been reduced quite a bit, and they run cooler.
By running cooler, the life expectancy of the motors are increased by 50%.
*Note, that's not the company I worked for, it's not their site and I'm not trying to sell you guys anything. I'm just passing on some little known information on how to save money.
They will be coming out with a new product that does the entire house and you can monitor your savings in real time via your computer. We'll be getting one when it comes out.
