Gassing, it just seems like the right thing to do, but there are so many options. I've been researching for about 1.5 years now, and have narrowed the field somewhat. If you have not seen my other threads, a lot of detail and pics are in them. https://www.hearth.com/talk/threads/englander-28-3500-furnace-install-mods.102100/ https://www.hearth.com/talk/threads/woody-mustash.110700/ My stove was getting up there in age, but it did a decent job helping out. I ran the Englander furnace last year. It did a good job. I have pretty much learned it's quirks. It will get better this year with better seasoned wood. But I am still burning 1 tank of oil in the winter and 1 tank in the summer for DHW & ambient losses through the oil boiler. Upward of 500 gal is no longer acceptable at today's prices. I still have hot & cold spots in the house. I think we have had enough of "central radiant heat from the middle." I have contemplated modding the Englander further. Add secondary burn tubes up top, install a large Hilkoil in the roof, run a constant circ pump and atmospheric storage in an effort to heat my DHW and pre-heat my baseboard returns to the oil boiler. I still forsee it being a semi-hack project, so maybe I should just go all out and do it right..... I have looked at: - Froling 20/30 + storage. - Empyre Elite. - Varmabaronen lambda & non lambda with exhaust fan + storage. - Garn JR. This really excited me, big tank and solar capable is a huge plus, but it won't fit inside, so I need a slab, outside boiler room, more property taxes, short run of piping to interconnect. Would also be a hassle to move should I decide to relocate to another house. And then I came across this tonight: http://worcester.craigslist.org/ppd/3946068975.html "Empyre Elite Wood boilers use half the wood of regular wood boilers. Indoor and outdoor models. Lowest prices of the year with instant rebates up to $1,000 during our Sizzlin' Summer Sales Event. Limited time only! Sale ends August 31st. Call 978-355-6343 x-231. Higgins Energy Alternatives 140 Worcester Road Barre, MA 01005 M-W 9-6:30, Th 9-8, F 9-6:30, Sa 9-4 " That seems like a decent price for a decent gasser that would fit my limited mechanical area. I'm thinking I could always run additional atmospheric storage with it, and that storage would also be suitable for integrating solar when the time comes. I have to make some calls to clarify if this price is indeed realistic. Any opinions?
