OK all you (us) New Englanders, the parties over. Don't get too used to these 45* days, cause after tomorrow, the frigid air is returning. (Finally). My stoves been off for a couple weeks now, and my oil tank has been (fortunately) dropping slowly. Usually in past winters, (not last year either), I've needed to fill my oil tank in January. Since the coal stove install, I can see the difference. My oil tank is still over 1/2 full. It's a bit temperamental using my Surdiac, but I'm enjoying the learning curve, (thanx to all you responders), and know in the future I can only go up. (I hope). For now, I'll play with this stove for a while. As for the next week of below freezing winter, Bring It On! Enjoy.
