| As said, based on that limited info, no one can give you an answer.
| But if your furnace can't maintain 70 when it's 20 outside, something
| is wrong and I doubt a return is going to do much to solve it. Is
| the furnace running continously?
same problem with brand new "concord 80 plus" oil furnace (forced air)
heating bill is $1200 per mth. in N.E.
why can't the furnace reach 70 degrees?
it has a hard time maintaning 68 degrees over night.
insulation .................well..................none. built in 1911
5000+ sq. ft. house
what size should the nozzle be?
