i have just found one in pretty good shape in someones basement. It is in really good shape on the outside but the inside is covered in creosote, the firebox and heat exchanger are just a mess. I have an old energy mate boiler already that i was thinking of swapping out for this tarm. The price is 300 dollars. I cant found much info this boiler, I was looking for burn times and how much more efficient this one is then the one i have already. My boiler now is a horseshoe shape tank that you can open the door and look right at the smoke pipe, not too efficient. any ideas any
