View Full Version : I Need A New Furnace
10-08-2005, 09:20 AM
I have a Old Williamson oil furnace that needs replaced.
I heat about 1350 sq ft with 550 gallons of oil a year
I am trying to choose between 80% or a 90+ Two-Stage Variable-Speed propane gas furnace. The installer I have contacted uses mostly Goodman.
Could someone tell me something to make up my mind and give me a Idea what size furnace I would need. I live in central Indiana. The Oil furnace is a 90000 btu about 25 or 30 years old last winter I started smelling fuel oil when it would start.

LP would be my second to last choice for heat. Electric being last. Look into a Thermopride furnace.
As far as sizing click on the RED tab above, spend the $ and do your own to compare with your contractors.

There is no natural gas available only choice is propane, oil,
heat pump, drill a new well and go to geo thermal.
Oil is over 2.25 a gallon propane is 1.79 gal First fill will be 1.49 gal on a 1000 gal tank. That should heat my house all winter then refill in the summer

But, oil energy is 140,000 BTU per gallon, vs. 91,000 BTU per gallon forpropane. Pricing by gallon comparison alone might be misleading?

Iím just giving my personal opinion. Oil and Nat gas over a 5 to 10 year period are about the same as far as cost per BTU output.
Someone on here a while back showed a breakdown of the cost of the fuel and the BTU output maybe they can show it again.
I would still go with oil.

You are still cheaper to go oil..
Did a calc on your price, for 100,000 BTU of heat, cost of oil will be $1.99, and LP will be $2.35 80% system.
Of you go oil, ThermoPride will be just as good as the old Williamson..
Now if you got your mind set on LP, going on the 90% system will bring it down to about $2.09

The Williamson has been a good furnace. We have lived here 14 years and other than filters and new pipes to the flue. I have spent $26 dollars on it in the 14 years.
If I am using 500 gal of oil how much propane would I use

How much is electricity?
Monday's job is removing a big old Willie oil and putting in electric & heat pump. Computer models say new oil furnace would run $2500 a year for heat and all electric with 12 SEER heat pump under $600 a year. 1 year pays for the electric upgrade needed.

Iíd like to see those #ís.
Look at the last post on this page and do the math.
Note: I donít verify these #ís maybe someone can.
