I had to switch to nat gas for my 95% eff. Condensate furnaces. I was on Propane, but my Son in law went to another company and the price went way up. ( my propane was 180-210/gal) The nat gas is WEAK, NO hot air, only warm..Only one supplier, who charges MORE, the more you use, Propane is opposite, Use more?, Pay Less/gallon. THis old house needs REAL heat. I hooked up a fairly small Coal stove ( hand fed). I get it started with some WV. Bituminous coal. ( same stuff they use at a power plant in the State) and then dump in the hard Pa. Anthracite. Nothing like 30 Million BTU/ton!! I use my furnace Blower only to circulate a couple times a day. My house is warm at 75 and Im lovin it!! Next is to hook one up in the garage with a coil and get the "pex" in the floor warmed up
Home heating oil hasnt gone down like gasoline has here.
Temp was MINUS 10 a few times already..
