A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel, since it contains three times as much interior surface area (compared to a single-pass boiler) to extract heat from.
Technical Advantages
Gas or oil burner compatible
Easy access swing door
May be direct vented with no flue required; can be direct vented outdoors with optional direct vent kit.
Low water content boiler heats up faster with less fuel
Efficient 3-pass heat exchanger boiler design
GG20 cast-iron construction for superior heat retention and durability
ASME, UL, and IBR listed
58 psi cast-iron construction
The B-10 boiler systems have been heating residential and commercial buildings throughout
the world for years. It has proven its fuel efficiency and durability in countries where fuel can cost up to
four times as much as in the U.S. The same fuel saving technology is now available here in North America. With the
three pass boiler design and low water content, heat is quickly supplied for your heating zones and hot water needs.
Combined with an outdoor reset control, you can achieve a fuel savings of up to 40% over conventional single pass boilers.
You will also have peace of mind since the B-10 boiler package complies with ASME and UL standards and is IBR rated.
The B-10 boiler system is the cost-competitive heat and hot water system of choice.
