Buderus G315/5 Cast Iron Hot Water Gas/Oil Boiler, Less Burner, Assembled - 433,000 BTU

The Buderus commercial Thermostream boilers are designed with many physical attributes setting them above the competition and increasing their longevity and efficiency. The burner doors are field adjustable to swing fully open from either side, to enable the boilers to fit in any location. These boilers are shipped knocked down for easy transport, the G315 can also be shipped as an assembled block. Due to the unique chamber design, no refractory materials are used. This reduces the number of service calls and maximizes heat transfer. Buderus precision castings eliminate the need for manual grinding. Precision beveled steel push nipples join cast iron sections and high temperature flue sealants are used to sustain pressurized operation. The G315 comes with a full 3-1/2" of thermal insulation to reduce standby heat loss. All Buderus cast iron commercial boilers are manufactured with the Buderus GL-180M cast iron with a silicon "barrier skin." To streamline the appearance of the boilers, the supply and return connections for the G315 are located at the rear of the boiler. These boilers are for use with hot water and can be installed with gas, oil or dual fuel burners. Buderus developed the full three pass system to increase the heat transfer and efficiency of boilers. This design allows more heat to be transferred during all three passes, unlike conventional boilers that only use one pass to transfer heat. This system maximizes the total possible heat available with the lowest fuel consumption possible.
