The most efficient cast-iron steam boiler in the world. The MegaSteam is a U.S. boiler exclusive. Designed specifically as a residential oil-fired steam boiler the MegaSteam achieves 86% AFUE efficiency with a 3-pass cast iron heat exchanger the only one of its kind in the world. Its unique design makes it highly corrosion resistant a fact that U.S. Boiler Company backs up by giving the MegaSteam the best
It is possible for a 3-pass boiler with a tube design (such as XID boiler tubes) that allows more heat transfer time to deliver the same or higher efficiency rating than a 4-pass boiler with standard tubes. 3 pass firetube boilers offer: maximized heat transfer; minimal
Cleanout hand holes 3" x 4" are furnished in the bottom of the boiler shell. Insulated with 2" high-density fiberglass the shell is covered with 22 gauge grip jacketing and spray baked on powder coat finish. 2 1/2" dia. steel firetubes (2" dia. through 30 Hp) are rolled and beaded on power boilers expanded and flared on low pressure boilers.
It provides maximum heat transfer and fuel saving by distributing the heat obtained equally to all surfaces with its three-pass design. Fuel tank provides high heating surface 1-3 days burning duration without the need for stoker. More heating is provided with less fuel.
Mohawk Three Pass Heat Recovery units are designed with a large diameter furnace for waste gas inlet temperatures to 2400°F with 2.5 heat transfer tubes. Categories: Mohawk WHRB
The B-10 oil boiler system is the cost-competitive heat and hot water system of choice. A 3-pass Biasi Fuel Oil Boilers are 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 Burnham boiler) to extract heat from.
The Q3 boiler is a hot water boiler heating system which oil-fired cast iron boiler offers high-efficiency. Its cast-iron design is recognized by heating professionals everywhere as the longest lasting most durable heat exchanger material. Your home will be more comfortable with an Q3 boiler because it does not use household air for combustion. It draws combustion air directly from the outdoors and expels
The Industry's Best Residential Boilers As a heating professional you know the boiler is the most important piece of equipment in any residential heating system. In addition to keeping your clients home at the ideal temperature the right boiler will provide it with reliable heating consistently and affordably for years into the future.
A three pass design provides three opportunities for heat transfer. The stack temperature of 3 pass will be lower than that of 2 pass boiler of the same design and operating pressure. Efficiency is more than two pass boiler. Each pass in boiler should be designed with cross sectional area to achieve optimal flue gas velocity which in turn maximizes heat transfer while also minimizing performance robbing sooth

The same oil fuel saving technology is now available here in North America. With Biasi's three pass oil 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 oil fired boilers.
Three Pass Central Heating Boiler ERG series. Easy Access and installation opportunity because of narrowness due to oval boiler body. Imbricated 3-pass design provides optimum thermal balance. effective heat transfer and low operating costs. Lower heat load by means of large water volume.
Dynatherm is America's ONLY steel and cast iron belly flue 3-Pass Scotch Marine designed boiler. Uniquely different from an all cast iron or all steel boiler Dynatherm boilers utilize the qualities of both materials. The cast iron front and rear heads are designed to hold the heat as they transfer it into the steel heat exchanger.
