Air It Out: You know those lovely ceiling fans that keep you cool during the summer? Reversing their spin in the winter (clockwise) pushes the hot air that's rising back down to your level. Genius! (Fact: For abbbbout two years I didn't understand the reverse air flow game and had my ceiling fans blasting hot air on me in, like, July. Sometimes, I think it's a miracle that I graduated from high school.) While you're at it, consider a humidifier, which helps the air hold moisture and warmth and has the added benefit of soothing your dry winter skin.
Bleed Your Radiators: Yup. This is another thing that took me about two years of home ownership to figure out. (Seriously, I'm just winging life .... like all the time.) Bleeding your radiator not only keeps you from, you know, destroying your expensive boiler, it also keeps you house WAY more cozy and your appliances using way less energy along the way.
Bundle Up: I know it's a big "duh," but throwing on an extra pair of socks or a sweatshirt will likely keep you from cranking up the thermostat a few degrees here and there. I'm not proud of it, but there was a winter when I slept in a woolen cap. What? And don't forget to turn down the heat a bit when you go to bed - You don't need it going full blast when you're snoozing!
So there you have it. Some basic tips for keeping your home cozy and your energy bills lower. AND with all the savings you rack up, perhaps a winter escape to a sunnier climate could be in the offing!
