I'm a newbie too but have learned a lot from this forum and everyone here in the past few months. For your size home the Keystoker KAA-2 would be a perfect boiler. The price is around $3800.00, ask your local dealer if he has any installers he can recomend to you and they should be able to give you an install price. Also bill is correct, 180 gals of oil is = to 1 ton of coal, you will probably need 3-4 tons depending on the amount of oil you normally use along with insulation and windows factored in too. If you call Keystoker they can direct you to a local dealer,www.keystoker.com, the KAA-2 has a 100lb hopper but I think you can get a larger one for it. If you're going to order one I would do it soon as they are already swamped with orders and will be hard to get i'm sure by fall.
