scarbowcow I've got an unheated hall that has damp walls (has had for more than 10 years; landlord won't do anything about it). I had an oil heater in the hall to keep the wall warm and keep it from growing mold, but it gave up the ghost (landlord won't provide another). I bought the cheapest space heater from the supermarket (heating element and fan), and I'm astonished by how quickly it heats up a whole room. Much more efficient than my wall-mounted steam heat and that electric oil radiator. I paid about $15 and am very happy with it.

kspollock I love the Eco heat flat panel as it can easily blend into the room. More safe space heater options here:

freyafoust We are on year 3 of rarely using our forced air furnace. Between day lighting, insulated drapes and recapturing heat generated inside the house we rarely need it. We keep a radiator type space heater in the living room we turn on at night or in the morning if it gets cold. I have a small fan heater to take the chill off in my office. We also run it to warm up the downstairs bathroom. The bathroom is toasty warm in a few minutes.

smanthacr I'm shocked you haven't featured Broksonic's Humidifiers I bought one 3 weeks ago at Gracious Home NYC and it's a pure fashion statement complimenting every room, it's a real conversation peace.

aebuildingsystems While they are not as cool looking, other options include more insulation, air sealing and good windows.

CAROLE MEYER Very cute for heaters!

freyafoust Actually I live in South Dakota. I grew up in Minneapolis, it is way colder here due to the terminal north winds. It can be done in northern climates if you have a well insulated house and properly placed windows. So far this year the only times we have turned on the furnace was when it was going to be -10F for an extended period of time. If it is only going to get to the teens at night and was at least 20F during the day we don't need any heat at night. It might get down to 54-60F in the house by morning but between the space heater and morning activities it is warm enough in less than an hour. I think people find this so hard to believe because they have been convinced otherwise. Take baby steps to cut your heat loss or lower your thermostat. The key seems to be having a well insulated house and either southern or east/west big windows. Everything in our house is contractor grade and it was built about 2001. Insulated drapes make a huge difference in keeping heat in.
