500 gallons of #2 heating oil is about 3 tons of coal (give or take, depending upon which is burning more efficiently).
I wasnt that far into my estimating of coal, but that sounds reasonable.
The oil boiler now can go thru 60 gallons in 3 days, I just experienced it!
the eff is not good, 50% is my guess with this converted crap boiler
I was contemplating if oversizing with the 260 would burn more coal on warmer days or during summer with DHW
than with the 130.
I dont see the 130 being able to do it without supplement, but just digging deeper to make sure.
But getting a 130 to find out I need a second or an upgrade, is not part of my plans.
