The heating season is done and all I bought was 16 gallons of propane!
I recently installed an indoor coal and wood boiler. What a treat!
I cut about 10 cords of wood and didn't get to burn any of it (too wet)
So I bought 3 tons of coal and burned that. Took a long time to get used to it but after a couple of weeks I only had to feed it every 12 hours.
It is looped into my existing propane boiler and if the fire goes out the propane kicks in. It's a little extra work that will save me thousands! If you have the time I suggest doing it! It will pay itself of in 2 years.

It also heats my domestic water.
this year I will be buring wood. more tending but much cheaper!
