Biasi B10 Series Boilers


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 peaceof 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.

Maximum water working pressure: 58 PSI. (1) The burner input is based on oil with a heat value of 140,000 BTU/Gal.; (2) The net output ratings shown are based on piping and pick-up allowance of 1.15; (3) The efficiency ratings are based on a combustion condition of 12.5% CO2. Warranty: The BIASI B-10 boiler has a limited lifetime warranty.
A copy is provided with each boiler or is available from your dealer. Built in accordance with the requirements of ASME boiler and pressure vessel code.


A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the boiler. The design extracts heat from three times as much interior surface area of the boiler, compared to a single-pass, “pin-type” boiler design.

Technical Advantages:
Gas or oil burner compatible, Easy access swing door,
No flue required; can be direct vented outdoors
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 listed58 psi cast-iron construction
