You guys are going to think that i am a real piker. I live in the San Francisco bay area and recently installed a pellet stove in my shop.

The older i get it seems that i become less and less tolerant to the cold. I have a small 850 sqft shop and it gets down into the mid 50's over night. With the pellet stove i just go out first thing in the morning and hit the run button, go have breakfast and by the time i am done the temp is up to around 60/62. It is wonderful!!
