Oil was even more expensive THEN! It's gone down five cents since that time (I kid you not).
Converting to another system is extremely impractical for me dollar wise, a new furnace is on the checkoff list but everything comes down to $$$ (I can't even afford to replace the existing tank I HAVE and am praying it will hold together for another year). Lately every time I start getting money together something comes along and cuts our legs out from under us, and we were doing so well until last April then everything went to utter shit.
Where I live in the mid Atlantic region the main form of heat is 1) oil 2) natural gas. Propane is VERY rare, coal is unheard of and solar is not practical for my house (1/2 of a twin, and again, $$$ to convert). Moving is not an option currently, either.
shit shit shit ... I can't catch a break in a bucket.
