My wife and I purchased a house in 2015 and remodel it. The roof is 25 years old and needs to be replaced. We have patched it up and have been holding off because I knew this was coming. Everything in the house is LED and Engerystar, etc. The 2 big power items are the hot tub and the heated floor in the bathroom. My power bill in my area has 3 levels and the 1st level is not enough for any reasonable usage. With the fully efficient house, removing the hot tub and heat floor I am still pushed to the 3 level of pricing which make my bill $300 per month. This as my new roof + the power wall is a no brainer for me. Where do I sign up ;)
