Good morning from Central VA. I've been lurking around this site for a while and figured I'd join up so I could post some things and ask some questions here and there. I live on a roughly 250 acre cattle farm just south of Lynchburg, VA. We've got a mixed herd, mostly black angus with some red hereford, charolais, baldy, etc mixed in. I've owned a Heatmaster MF5000 for a few years now and really enjoy the unit. I've picked up some do's and dont's just from trial and error of owning and operating the furnace. Some good, some bad. We live in a roughly 3,000 sq ft farmhouse that was built in the early 1900's. The total heating space of the home is about 2,200 sq ft excluding the 3rd floor attic space. I've gotten some really good tips from the site and hope to extract some more info from you all. Thanks again.
