Hi All. I'm new to this forum and have never belonged to a wood burning forum. Currently I'm running a New Yorker WC-120, and have had it for 21 years. When I built my house (21yrs ago), fuel here in NY was expensive approx. $1.20/gal in 1985. Back then, I was looking into multi fuel boilers, but they were too expensive, around $2000+. Looking in my local newspaper, I found someone selling a 5yr old New Yorker for $200, so there we have it. My system consists of an oil fired boiler and is piped to my WC-120 in series with the wood boiler feeding the oil boiler's return. By closing 2 valves and opening 1, the wood boiler is taken out of the loop and the oil boiler is in the conventional hydronic loop. The wood boiler hasn't been used in the past years much because fuel prices haven't high enough to warrant my breaking my butt collecting firewood, this year has changed. This past July my steel New Yorker oil boiler's heat exchanger rusted through and sprung a leak forcing me to replace the boiler (I had been putting this job off for 2 yrs). While ripping the system apart I almost eliminated the wood boiler. Since it wasn't costing me anything to keep it, and the unstability of the oil market, I decided to keep it. When I installed my heating system 20+ yrs ago, I made it semi-automatic, so my wife could load it while I was at work. My only problem with this thing is that it's a wood hog, it burns wood like there is no tomorrow, I have to re-load every 2 1/2hrs max. The boiler is supposed to burn coal also, and it takes the large "stove" coal. During the day I would burn wood, and in the evening I would try to burn coal to last through the night. After loading the coal and having a nice "banked" fire I would retire to bed to only wake up the next morning and find all unburned coal. How much wood do these new gasification boilers use? Is the high price of these things worth changing over to?
