Biasi 3Pass Cast Iron Boiler Featured Product

Biasi Oil Fired 3Pass Boiler

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.
