Note: Product Title reflects this boiler's IBR Net Output Rating
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.

Q:Is this boiler an outside boiler
Q:can this boiler be converted to NG, I need oil boiler today but hope to have NG down the road.
A:the compatible gas burners are listed on page 19 of the installation instructions
A:only way to "convert" to gas, is by changing out the entire burner unit... according to Biasi, the B-3 (and all the B-10 line) can use gas or oil.... the pdf "submittal sheet" states such... but there is no listing of compatible gas burners... also the efficiency of the boiler is lower with gas
A:according to Biasi, this boiler CAN be used with either oil or gas burners..... look in the PDF "submittal sheet" document under the Overview Tab... google around and you can find more info on Biasi boilers, according to manufacturer, all Biasi cast iron boilers in the B-10 line, B-40 line and the SG Pro can use oil or gas burners... I've yet to find any documentation about what exact gas burners they refer to, or whether the listed MBH input/output and efficiencies are based on NG or LPG.....their chart shows lower Gross/Max inputs/outputs for gas than oil, but more importantly, the efficiency drops off... AFUE for oil is rated at 87% ... gas direct vent is 85.5%, 84% chimney
A:oil burners can not be converted to NG.
Q:A question out of curiosity. Your website says that Input heat is 80,000 BTU and output heat is 58,000 BTU. When I divide these numbers I get 58,000 / 80,000 = 72.5%. This should be the effriciency. Why do you say it is 86.7% efficient ?
A:AFUE efficiency ratings (86.7% for this boiler) use DOE output ratings and an input below the maximum. This boiler has a DOE output rating of 67,000 BTUs. DOE ratings assume that a boiler is installed in a heated space and that any heat that comes off the boiler jacket and surrounding piping goes toward satisfying the heating load. The 58,000 I=B=R rating assumes that this heat is wasted. The AFUE efficiency rating uses The DOE rating and an output of approximately 77,300 BTUs (slightly below the 80,000 maximum) in order to achieve the 86.7% number.
Q:do i need a water tank
A:This unit cannot produce hot water without the use of an indirect water heater. It does require an expansion tank.
