Features
    The Buderus G315 oil boiler is a complete home oil heating solution that works equally well in both new construction and renovations of existing buildings. The three pass heat exchanger extracts every last possible BTU of heat energy out of the oil supply, resulting in higher efficiencies across the board. The flexible cast iron included in the boiler's construction, giving the boiler fantastic resistance to thermal shock. Combined with its installation versatility and optimal connection placements, the G315 is a boiler package that will last your home for many years to come.
  • Three-Pass Heat Exchanger
  • The three-pass heat exchanger included with the G315 allows the water to be heated three separate times, allowing a higher water temperature to be maintained throughout the system while improving heating efficiency.
  • Fully Thermally Insulated
  • The G315 boiler is encased by three inches of thermal insulation, keeping generated heat inside the boiler during downtime and preventing heat loss during uptime.
  • Ideal for New Installations or Renovations
  • The G315 boiler is ideal for both new construction and renovations of aged housing due to its adaptive heat exchanger and optimal connection placement.
  • Flexible Cast Iron
  • The heat exchanger of the Buderus G315 boiler is made of patented flexible cast iron, allowing the boiler to resist even the most punishing thermal shock.
  • Product Includes
    • (1) Buderus G315/9 - 768K BTU - 87.1% Combustion Efficiency - Hot Water Gas/Oil Boiler - Chimney Vent - Assembled - Burner Sold Separately (7738000269)

Cast Iron
Fuel Type ? To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Oil
Combustion Type
Conventional
Vent Type ? Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Chimney Vent
DHW Production ? DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.
No
Modulating/Staging ? Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

What is the difference between a conventional and a condensing boiler?
Jagdish 
from New York 
October 31, 2016
Answer
Condensing boilers use the condensing process to extract extra heat from the water vapor in the flue gasses. By condensing the water vapor back into liquid water, they can use this heat to increase the efficiency of the boiler by 10% - 15%. In a conventional boiler, this extra heat typically escapes up the chimney and is wasted.
