Wow, I guess I didn't get hammered too bad.
Last summer when I had the tank set, it was $2.49 per for 150 gallons
10 days ago I had them return to top it off and it was $2.09.
It is a 250 gallon tank, only providing fuel for the 125kBTU Reznor in the shop.
But momma is gonna make me install a new stovetop next summer, and it'll be propane, and we are gonna do a gas water heater as well, so things are going to change.
But getting away from all electric should knock our energy bills down, too.
...On the wood BTU, hardwood like Oak, Madrone, etc. has a high BTU rating than pine or other softwoods simply becasue it is denser and burns longer. This is the explaination I have been given.
Whatever the reason, hardwood is better. We heat the house almost exclusively with a airtight woodstove, and it would take 3 cords of pine to do what 1-1/2 cords of good seasoned Oak will do, not to mention stuffing the stove full far more often. A good chunk of Oak or two stuffed into it at 11:30, and dampened back will still have enough coals left to fire off a stick of pine the next morning. Pine/cedar is great for easy starting, but it does not last.
IMHO/ Yer mileage may vary.
