I bought the clear keyed covers at home depoe ten bucks, in isle by door locks!
My goal is to not turn our heat on until October 1 or when the plumber is able to get here to do the annual maintance on it (whichever comes LAST). Every time it kicks on I just think of all the money that is being burned!
Our house normally ranges around 65 degrees this time of year but today it got up to 72 because i was using the oven a lot. I'm not sure which costs more-electricity for the oven or oil for the furnace but at least with the oven I get something yummy to eat!
