Long time/ repeat lurker -- Because I keep thinking coal may be my solution.
My situation: 1750sf two building well insulated Studio in Bucks County Pennsylvania. It's my second residence -- so the studio is not occupied all the time. I currently have a 32K BTU propane heater (hot air) and two 220V electric heaters. I run the propane when I am away to maintain something around 55 and then up the propane and add in the electric to get it up to the high 60's maybe 70. My delivered propane hit almost $6 per gallon last winter
. I'm going to be using this place a bit more for the next couple of years and expect to move permanently after that .. so some of this is planning .. I have to do something.
The previous owner (2005) used to heat the space with a wood stove. He installed the propane heater because, like me also started to use the place intermittently -- and propane was only $1. The chimney (masonry) is still there .. I love the heat from a wood stove ... but wood is pain .. especially when you have to buy it.
I'm wondering if it is unwise to try and heat with coal intermittently -- I often arrive in the evening and stay 4 or 5 days ... Will lighting become to onerous? ... will I have to clean out the cold stove each time? How fast do you begin to get heat from a coal stove?
When I read the forum -- I'm thinking an old stove like a Glenwood Basebuner is just what I need ... or should I get a new stove? The old ones are confusing -- Glenwood #6 vs #8 .. I guess the 8 is bigger? Also, is a Glenwood Oak a base burner? or something else. I could also have a small amount of wood around .. as some burn both.
The idea of a small boiler is very interesting ... but thats further down the line.
