Trio

Oil Boiler w/ Riello Burner

The TRIO results from 50 years of engineering and manufacturing experience. With its low mass design and efficiencies of 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 manufacturing process is a better engineering technique than boiler sections, assembled 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.
