The Buderus G115WS boiler is based on the highly successful G115, the World’s best selling boiler. The G115WS has been redesigned and re-engineered to extract and deliver more heat form every fuel dollar, and now has higher outputs at less cost per BTU.

Technology:
Optimized combustion with positive pressure-fired boilers and chamber geometry – no need for a heat-consuming refractory or target wall eliminating the need for costly repairs.
Minimal stack losses with the modified three-pass flue design’s largest heat transfer areas.
Low standby losses with a full 3″ jacket of thermal insulation around the entire block — even underneath the boiler!

The TRIO is the result of 50 years of engineering and manufacturing experience. With its low mass design and efficiencies up to 87% AFUE, TRIO addresses growing concerns about fuel prices. Recirculating flue gas technology reduces fuel emissions and sets the standard for environmental integrity. The TRIO is constructed of GG20 cast iron for greater durability and thermal shock protection.

The TRIO is a low mass boiler with steel push nipples. This manufacturer process is a better engineering technique than boiler sections which are put together with gasket materials. The low water content makes this boiler more efficient. A description of a British Thermal Unit (BTU), “the amount of heat required to raise 1 pound of water 1 degree Fahrenheit” shows that a boiler holding less water will be more efficient, especially considering that a gallon of water is over 8 pounds.
