Today's thrifty tip is keep your thermostat lower to conserve heat. For each degree lower it will save you 2% on your heating bill according to most institutes. I don't run my heater as much during the winter since I live in sub-tropical weather. When I do have to run it, then I keep it set at 65 degrees during the day. It does get chilly in the house so I just wear warm clothing. At night I still keep it around 65 degrees. Many experts say you should turn the heat down to 55-60 degrees at night. My husband would never go for this. I am on natural gas so my bills aren't extremely high. There are many days we don't even turn on the heat like yesterday and today. My monthly average over the course of a year is right under $50/month. I pay $25 during the summer months for my gas water heater, dryer, and stove. I don't use the dryer that much either except during winter.
Investing in a programmable thermostat is another great way to keep your house energy efficient. If no one is in the house during the day, then you program it to keep the house cooler during the winter and warmer in summer. You can also program it to have it start warming the house up right before you wake up in the mornings. Have it get colder when it's time for bed. I need to invest in one for myself.
