Thanks for the replies guys. Yep, F%#k OPEC indeed!
Anyways, with regard to the rest. House is about 2000 Sq Ft. Surrounded by wood, but would be buying it in cords, cutting etc.. As I understand it, the unit takes the wood without splitting as long as it's the right length. It is also piped thru the water heater (don't ask me how, I have no idea!) as well as the water/air heat exchanger.. It's been in situ since about 94, so it is grandfathered. The wife says, "No No!" she doesn't want it hooked up, but would rather get a pellet stove to heat the house. However, I'm looking at the costs involved in putting that in as to getting the outside burner going. The only probs are that since no one knows exactly where the water leak is (only that its outside between house and unit - about a 50' stretch see pic) it would require ripping up part of the grass, and it goes under my deck, which is quite a substantial structure, and not something to be taken down and put up again in a couple of days! Then there is the stoking of the unit in mid winter, when it's down to close on -50 with windchill, and the burner is at the bottom of the garden with not much else around for miles, it's a long walk in a blizzard!
So there you have my dilemma!!
