Depend on your age how long you planning to live in that house
I don't know cost of new boiler I would estimate $4000.00 +-one
install by license person, Where I am hot water heater coast
between $1400.00 & $1600.00 plus town permit install by Home Depot
so you recovery time could be anything around 20 years
you figure is it worth changing or staying with old one.
good luck!

The boiler with Beckett AF burner was here when I moved in. I assume
the HE stands for high efficiency, but what was that 20 years ago? I
could keep this boiler going for a long time, but wanted to check if
it's worth it to replace with new. The Weil-McLain website has a
calculator but doesn't have the info I need. It shows a 78% default
efficiency; going from this to 86% or so saves me a little over $200/
year (at $2.40/gallon). Seems like that'll take quite a while to
recoup at a boiler equipment only cost of over 2 grand.
