To get an answer to that question, you should start with some other questions that will help determine just how efficiently you’re heating your home.
• Where is the warm air going? If you’ve got a leaky house, you’re costing yourself money, plain and simple. Heat ends up escaping and cold air keeps flowing in, which means you either turn up the thermostat or just shiver in your living room. The U.S. Department of Energy recommends getting an energy audit so you can find and seal the gaps.
• When is the heat on? Are you keeping the house at the same temperature all day and night? Even when you’re or sleeping or at work? There’s no reason to, and programmable thermostats mean you can still have a warm house when you wake up and when you get home.
• Am I maintaining my system? A lot of homeowners simply forget to do things such as changing their air filter regularly or getting periodic examinations of their furnace. These routine tasks can not only prevent more costly problems down the road, they can help you more effectively heat your home right now.
• Is my fireplace hurting more than it’s helping? It could be, if you always leave the damper open even when you don’t have a fire going. And, if you have the damper closed, a leak can make it yet another place where warm air gets out and cold air seeps in. Check the seal around your damper, and consider using a chimney balloon when you aren’t using the fireplace.
Taking some time to answer these questions can increase your efficiency, decrease your bills and perhaps even prompt another, more pleasant question this winter: “Is it too warm in here?”
