: The sales person said they advertise 40%, but probable more like 50-60%. Are these numbers realistic, or am I better to stick with what I have?

: To quote the Biasi web site, you would have a boiler with an efficiency of:
: "The BIASI B-10 is a rugged, high performance, oil/gas fired, cast iron boiler engineered to deliver effiencies as high as 87.3%"
: http://www.qhtinc.com/efficiency.html

: So there isn't much difference between what you have and what you would get. You can't get 40 to 60 percent more efficiency from a boiler with about 85%, that would be 120% which is impossible. If the salesman was talking about going from a cast-iron oil boiler of 86% to a cast-iron oil boiler at 87%, he is the typical lying rip-off artist.

: Any difference in money savings would happen when changing from oil to natural gas, which is about half the cost of oil now.

Mine is not a cast iron oil boiler. It is a typical single pass boiler. I found out that the 86% is just the burner rating, and not the actual furnace.
