Time to replace the Oil Furnace

[Scuba_Dave]

Well I knew this day would come when we bought the house
The furnace is now 20 years old, just tuned up
There is a part broken, they patched it with cement
Efficiency is down, needs to be replaced

Looking at close to $5k for a new one installed
If we went thru 3 tanks of oil a year it would pay back fairly quickly
But with the insulation & new windows we only use 1 tank of oil a year
We have already saved the cost of the windows in 4 years
So we may "save" 80 gallons a year once we open up the sunroom & great room. I guess at $3 a gallon that equals $240 a year
Not something you ever break even on
It will take 20 years before we save the cost of the furnace in oil at todays prices

But no choice.......
At least we can wait until Spring/Summer & it's not an emergency
I trust or Oil guy, he's been very good to us

Any suggestions?
