        Comments about ESC4, 78,000 BTU Output Cast Iron Gas Boiler:

        We use this boiler to heat our 100 year old home. We downsized from a 133000 btu boiler to this unit. We have no problem satisfying our heating needs even at -20*f.

        One caveat: the listed ratings are incorrect. I believe that all the ratings have been modified to reflect new testing standards. The ESC4 is now rated at 91000 input, 78000 net, 68000 IBR as per the boiler rating labels and included documentation.

        As with any new heating unit installation, make sure to perform an accurate heat loss calculation to determine what size boiler is actually needed. As I said, we downsized from 133000 input (105k out) to 91000 input (78k out) and probably could've dropped down to the ESC3 safely. We stayed a little larger so we could add a basement zone in the future and an indirect hot water heater next year.

        In short, great boiler, great controls, extremely quiet, attractively packaged, good price. We opted for the 85% efficiency instead of the higher efficiency condensing unit simply because of the reliability of cast iron heat exchangers. Our payback with a higher priced modulating/condensing boiler would be about 14 years more, which is about their expected lifespan.

          Q:

          Elevation is in question, I live at 5000' above sea-level. ESC6 rplacement has been chosen for 2000 sq' with finished basement. Original windows and insulation. Other recommendations.
          Thank-you

            A:

            ESC boilers come standard configured for installations at elevations up to 4,999 feet above sea level. High-altitude models can be special-ordered for 5,000 feet and above. If you are at exactly 5,000 feet above sea level, you could likely use either model of the boiler, but you may want to consult the manufacturer or installers in your area.

          Q:

          What is difference in venting an ESV boiler vs a PV series and is there an advantage of one boiler over the other

          • CUSTOMER CARE

            A:

            Burnham's ES2 boilers are chimney vented, while their Independence PV Series models are power vented. PV models are designed for steam systems, while the ES2 works with water.

        • ESC5, 104,000 BTU Output Cast Iron Gas Boiler

          Q:

          Is this equivalent to a modulating boiler when the optional outdoor reset module is added?
          Asked on 3/15/2012 by Carl from Anchorage, AK

          1 answer

          • CUSTOMER CARE

            A:

            In a certain sense, but modulation mainly refers to a reduction of fuel and combustion air input based on indoor heating needs. Additionally, most modulation boilers also condense. They are known as Mod/Con boilers. Condensing boilers condense exhaust flue gases for reuse, and they operate at peak efficiency when water temperatures are relatively low (below 140°F). They are ideal for in-floor radiant heat systems or low-temperature baseboard radiators.
