I looked into the Tarm but don't want to spend the money. I need to heat about 1,800 square feet in the Mid-Altantic. Currently I use a VC Resolute, and so far my problem is more too much heat that not enough, though not always in the right spots in the house. I use fans to move the air around. I am looking at the OM22 OilMiser as it is supposed to be able to burn BD, though anecdotally I've heard it needs a touch of Kerosene or HHO 1 to stay happy. It's also apparantly very sensitive to fuel quality.
If I were building a new house I would either adapt an oil furnace for BD or look into either the Tarm or a wood boiler. How many btu's is a standard furnace for a 2,500 sq foot house? -Mike Appal Energy wrote: >Or... > >http://www.alternateheatingsystems.com/woodboilers.htm > > > >>And on a smaller sale... >>has anyone ever looked into these: >>http://www.woodboilers.com/wood-gasification.asp ? >> >>More to the point, has anyone ever tried BD in one of thse? >>http://www.woodboilers.com/multi-fuel-furnace.asp >> >>-Mike >> >>Keith Addison wrote: >> >> >> >> >> >>>http://www1.timesofindia.indiatimes.com/articleshow/1267007.cms >>> >>>THE TIMES OF INDIA >>>EDITORIAL >>> >>>Realising Gandhi's village ideal >>> >>>Anil K Rajvanshi, Ph.D. >>>Director >>>Nimbkar Agricultural Research Institute (NARI) >>>Phaltan-Lonand Road, Tambmal, >>>P.O.Box 44, Phaltan - 415523 >>>Maharashtra, India >>> >>>Ph: 91-2166-222396 >>>Fax: 91-2166-220945 >>>E-mails: <mailto:[EMAIL PROTECTED]>[EMAIL PROTECTED] >>> <mailto:[EMAIL PROTECTED]>[EMAIL PROTECTED] >>>http://nariphaltan.virtualave.net >>>http://www.nariphaltan.org >>> >>>October 19, 2005. >>> >>>This is the Age of Electricity.
