IN THE ITALIAN ALPS, WINTERS ARE COLD AND FUEL IS EXPENSIVE

If necessity is the mother of invention, it's easy to understand the design evolution of the incredibly efficient BIASI B10 home heating system. Winters in the mountains of Northern Italy can be very cold. What's worse, heating fuel is three times more expensive than in the U.S.

The BIASI B10 Boiler is the heart of an ingenious engineering adaptation to a difficult situation—by a people known for innovative design and superior craftsmanship.

Add a bit of Yankee ingenuity (in the form of Hi-Pressure burners, electronic controls, indirect hot water heaters, and cabinet design technology) and the BIASI B10 has evolved into one of the most efficient hydronic home heating and hot water systems on either side of the Atlantic. Fortunately, it's also one of the most affordable.


THE ULTIMATE IN HYDRONIC SPACE HEATING TECHNOLOGY

The BIASI B-10 is a rugged, high performance, oil/gas fired, cast iron boiler engineered to deliver effiencies as high as 87.3%; much higher than that of 'single pass' domestic boilers.

Utilizing a unique triple-pass heat exchanger and an extremely low mass, the B10's heating surfaces extract the maximum heat fromt the combustion gasses, resulting in very little wasted heat.

The B10 Boiler is virtually indestructible, constructed of flexible cast iron, ASME rated at 58 psi. It uses very little water compared to conventional single pass boilers. Its compact design makes it suitable for installation in small spaces.

In short, the BIASI B10 offers home and building owners an affordable, versatile, long lasting heating system that provides super high combustion efficiencies and considerably lower fuel costs.



ALL THE HEAT & HOT WATER YOU NEED…
AT A FRACTION OF THE COST

Our B10 Boiler, coupled with an indirect storage tank, will supply all the hot water you need; which means no more cold showers.

In the summer, the B10 boiler only needs to fire once or twice a day, because ample amounts of domestic hot water (DHW) are readily available in a 40-gallon indirect storage tank. Compare that to a single pass boiler, which may use a tankless coil to make DHW. This requires the boiler to maintain 160° F temperature, continuously (even in the summer) to sustain your hot water supply. With the BIASI B10 boiler and an indirect storage tank, you’ll always be in hot water, and at a lower cost than a conventional boiler system or an electric water heater.

OPTIMISE YOUR HEATING SYSTEM

An outdoor reset control can drastically improve the efficiency of your heating system. This type of control functions by electronically adjusting the boiler temperature according to the outdoor air temperature. Automatically reducing the boiler temperature on milder days and increasing it on colder days. Ultimately keeping the boiler at the necessary temperature on any given day, saving valuable fuel.

An outdoor reset control provides better fuel efficiency and comfort with far less environmental impact and less heat lost "up the chimney".

Bigger isn't always better: Large-Mass vs. Low-Mass

If you were heating water for a cup of tea, would you use a pasta pot or a teapot? Think of the typical, large-mass, single pass boiler as a pasta pot and the BIASI B10, low-mass, 3-pass boiler as a teapot. Heating systems in today's houses only hold 5-8 gallons of water. Why burn all the fuel necessary to heat 17 gals. of boiler water in a 600lb., single pass bioler? The low-mass BIASI B10 with it's 3-pass design and 4 gals. of water content will satisfy the call for heat before the single pass boiler has even warmed up. The single pass boiler has heated twice the amount of iron and four times the amount of water. All that excess heat goes "up the chimney" with your fuel dollars. BIASI B10...the right size for the job.

Biasi B-10 3-pass

Because it's heat exchanger path is 7.3 ft. versus 1.5 ft. for a single-pass, "pin-type" boiler, our 3-pass boiler heats more surface area per gallon burned with 50% less heat loss up the chiminey.
