Plus another one for the Buddy Heater -- love my Mr. Heater. On a full cylinder, I've found it will run for about 6 hrs on Low and it heats the studio/snake room (a small spare bedroom) to the upper 70s when it's cold out, low 80s when mild. Also, we have a woodstove against the adjoining wall, which helps tremendously. We avoided an outage last night, but lost power to the storm the day before . . . it's a relief to have a plan with everything ready to go. Especially after once losing power for 7 and a half days in the 2007 wind storm and relying entirely on the woodstove when the propane ran out. Not fun but very doable. Depending on where you are, a small generator set on the porch to run a couple heat lamps or an RPH can also work in a pinch. But, yeah. Buddy Heater.
