High Efficiency Comfort
G215 Series Oil Boiler
Putting Energy to Work! Buderus developed a full three-pass system which increases the efficiency of the boilers. With single-pass boilers, the flue products have only one chance to heat the water. Buderus three-pass boilers triple this opportunity. The unique way heat flows through the G215 boiler allows the water to be heated three separate times. The full 3” thick thermal insulation helps to maintain a higher water temperature even after the boiler has gone into standby mode. The distinctive chamber design of the Buderus G215 also allows for nearly silent operation.
