So what kind are you guys using? Which ones are good and which ones suck. I bought a quarz kind with a fan. What Im looking for is to buy maybe 2 or 3 of them. Keep one in the living room, one in out bedroom and one in the kids room so I can lower the thermostat in the house and go more than 3 weeks before I have to keep filling the propane tank. From what im getting is the oil filled convection ones are probably the ones that would work best for what I want to do. Discuss.
