Jan 01, 2009 · Increasingly, cast iron boilers are being replaced with multiple modulating-condensing (mod-con) boilers. In the mid-50s, when many of the boilers replaced this summer were new, natural gas was going for 7 cents per therm. Today energy prices are causing a surge in high-efficiency boiler replacements.Get Price
Nov 14, 2018 · This system uses a mod/con boiler, likely fueled by propane in rural locations, to cover times when the load is greater than 75% of design conditions. That boiler is piped across the upper portion of the thermal storage tank. This allows it to "exercise" the thermal mass in the upper 10-20% of the tank as a deterrent against short cycling.Get Price
