Hi - I just got a Hearth Stone Heritage! That's the good news. My oil fired, steam furnace just cracked! That's the bad news. I want my wood stove to run most of the time, but I need a back-up heating source. Replacing my furnace is incredibly expensive ($8,000), gas is not available, and I have steam radiators. I have received some incredible advise on this great forum - So here's another question - What system should I install for a back-up to wood? Electric? Convert steam to hot water? Solar ? (I'm in the northeast). Thanks!
