- Oil-filled heaters - I swear by these things. I've used them since I was in the dorms, and am convinced they're safe around pets & kids & furniture. I'm wary of the regular space heaters, but I love these things. For our 1200 sq ft home, we have 2- one in the living room/kitchen area and the other in our bedroom.
- Closed doors - For the areas without heaters (basically, the bedroom we use as an office, and the bedroom we use as a guest room/game room), we close the doors. We don't need to heat space we're not using, and these rooms don't get used very often- even less so with our new laptop.
- Baking - Cooking dinner in the oven as well as cooking treats results in warm food as well as warmth in the kitchen. When I'm done cooking, I crack the oven door and let the heat escape the oven into the rest of the house- I paid for the energy to produce that heat, so I might as well let it do double-duty!
- Window insulation kits - I had heard of these, but hadn't actually seen one until we were wandering around Menards one day. The kits were really cheap, so we picked up enough for the windows in our bedrooms and master bath. The plastic is amazingly invisible, and hopefully the extra layer is helping with drafts.
- People insulation - Wearing socks in the house does wonders.
- Other insulation - We wrapped our water heater in a water heater blanket, and have heated insulation on our pipes to prevent freezing (when we remember to turn it on!) A big-ticket, someday, wish-list item is new siding & insulation on at least the west side of the house (where the wind comes from!) I can dream...
- Hot drinks - Tea, chai, & hot chocolate make us warm inside.
All these allow us to be toasty warm in our old house in the winter, while still keeping the thermostat set fairly low. What strategies do you use?
