Hi...
We have a 28 year old oil furnace that has started behaving oddly (starts and stops a lot). Given the price of heating oil this year and the fact that it was behaving funny we were thinking that this might be the year to upgrade the old furnace with a new one. Our oil delivery guys sent a repairman out to check out the furnace, and he said that the old one was burning at 79% efficiency while a new furnace might burn at about 83% efficiency and cost $5000 (installed).
The neighbors across the street replaced their furnace last year and they said they've seen a significant drop in oil usage.
Is there some disconnect between what they say is the efficiency rating and actual use?
Thanks
