I have a 30 yr. old dry base Utica boiler with a Reillo burner head
(fairly new). I have no idea of its effeciency. The unit runs
great. I live on Long Island in NY with cold winters and am using 180
gallons to heat my basement (a constant 73) and make hot water (Bock
heater and 5 adults). I have a Coal stove that heats my upstairs so
the heat rarely comes on for that part of the house.
I was thinking of replacing the oil fired boiler with a Boderus or
Well-Mclain Ultra, both have 90% effeciency ratings. I wanted to hear
from people who have changed out their old boilers for newer models to
find out if there really is a big savings?
Thanks in advance
I've asked the same question of local (Westchester, NY) fuel oil service
techs, and the answer I'm getting is to leave the 85% efficiency boiler
alone. I wire boilers with "hi tech" controls like Logamatic and Tekmar, and
although they claim ultra high efficiency, I question reliability and who is
going to service them. The oil companies pretty much don't want to stock
parts for these things and my impression is that they don't want to learn
how to program or operate them either. IMHO, I'd wait until this stuff
becomes more mainstream before I'd switch
I guess I should have said that I used 180 gallons from 2-11-07 to
3-11-07. Granted this is was a cold month but the boiler was monstly
making heat for the basement and hotwater. I currently have a coal
stove upstairs and the heat rarely comes on for the upper floors. My
home is about 2000 sq. ft. and has new windows and heavy insulation in
the attic. In past winters I usually use about 200 a month to heat my
basement and upper living spaces. Granted I never have kept my
basement at 73 before either. We have an office down there for the
wife and she likes it warm.
Just a small note on this. The service techs could be referring to
the boiler's combustion efficiency as opposed to its AFUE, in which
case, you would then multiple that number by 0.85 to allow for standby
and stack related losses. On that basis, the real number (which you
would use to compare with a new boiler) may be closer to 72 per cent.
