Keeping Heating Costs in Check

With oil prices out of control, I have implemented a plan to reduce my oil bill.
1. Keep the thermostat at 64 degrees. With sweaters, long pants, and socks, it is quite comfortable.
2. During the weekend and evenings, I start a fire. With the insert in the fireplace, it keeps the downstairs warm enough to keep the boiler from firing off.
3. Insulation. Using materials from home depot, I have insulated the pipes in the basement.
