Hi,
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
