Thanks again for all the helpful replies. You all have me thinking...IF we get the house (still TBD) maybe we should look good and hard at a coal boiler? If we wanted to tie that into the oil boiler, will that drive the price sky high? I'm just starting to peruse the boiler threads, so feel free to point me to any good ones
. I'm thinking we could probably pay for that install in a matter of a few years considering how expensive fuel oil is these days, considering that house will likely cost $5-6k in oil to heat.
