Aerco - Multi-Fuel Condensing (MFC) Boiler
AERCO`s MFC (Multi-Fuel Condensing) hydronic boiler is capable of firing with multiple fuels including natural gas, propane or #2 fuel oil. It features a proven 4-pass fire tube heat exchanger design for maximum heat transfer and efficiency and is designed for condensing application in any closed loop hydronic system. The heat exchanger’s combination of high quality carbon steel/316Ti stainless steel construction ensures the highest degree of durability.
- Condensing, gas-fired, fire tube boiler
- Multi-fuel capability: natural gas, propane, or dual fuel (#2 fuel oil)
- 3000, 4000, 5000, 6000, 8000, 10,000 MBH
The 316Ti SS construction in the heat exchanger’s 4th pass offers superior corrosion resistance against acidic flue gas condensation. Likewise, it can be fired with multiple fuels including natural gas, propane or #2 fuel oil (as backup), offering dual fuel flexibility. Moreover, the MFC series features dual return connections standard for optimal application flexibility and seasonal efficiency gains of up to 10%. The heat exchanger’s maximum working temperature of 240°F allows for greater operating temperature range and meet the requirements of higher temperature applications when necessary, but allows for the building to reset water temperature for condensing in the shoulder months.
The MFC Series is fitted with industry leading power burners whose emissions will meet most stringent NOx and CO requirements. The fully modulating burner also maintains AERCO standards for energy efficiency, longevity, reliability and construction quality.
The MFC boilers can be used as an individual unit or in modular arrangements and offers selectable modes of operation. In addition to controlling the boiler according to a constant set point, indoor/outdoor reset schedule or 0-10V signal, one or more units can be integrated via Modbus communications protocol. For boiler plants ranging from 2 or more boilers, an available sequencing controller designed to optimize plant efficiency provides the right solution. Likewise, MFC systems can be easily integrated with a facility-wide Energy Management or Building Automation System.

AERCO Control System (ACS)
The ACS is the best choice for maximizing heating plant efficiency if your heating plant has more than eight boilers or if you are designing a combination control system. There is an ACS relay panel available to provide additional pump and valve control for several combination control configurations.
Motorized Valves
The Belimo F6...HDU Series 2-way butterfly valves are designed to meet the needs of HVAC and commercial application requiring bubble tight shut-off for liquids. Typical applications include boiler isolation, chiller isolation, cooling tower isolation, change-over systems, air handler coil control, bypass and process control applications. Valves specifically designed for easy installation on BST configured boiler plants are available as well.
Boiler Sequencing Technology (BST) Integration Panel
BST boiler plants have this option available to enable the BST Master to automatically switch a C-More Slave to the BST Master control if the currently designated master is not able to manage the boilers in the plant. The change is automatic so there is no need for a technician to intervene. The C-More may change from a slave to a master if a unit is taken down for service or if there is a fault that disables the C-More currently acting as the BST Master. The panel is the connection point for the Modbus sensors used by the BST Master Control. This allows the signal input of any sensors attached to the Integration Panel to be accessed at any node on the BST communication cables.
AERCO Protonode/Gateways
AERCO offers a multi-protocol, communications gateway to support integration with customers’ building control and energy management systems. The plug-n-play package supports integration with BACnet/IP, BACnet MS/TP, LonWorks, and Johnson Controls Metasys N2 systems. AERCO’s Communications Gateway is available for all AERCO boilers, water heaters and electronically controlled indirect systems.
Condensate Neutralizer Kit
AERCO Condensate Neutralizers are ideal for neutralizing condensate from condensing boilers and furnaces operating on natural gas or propane. The condensate is acidic and has the potential to harm the environment and the sewer system. The AERCO Condensate Neutralizer will raise the pH of the condensate to a more neutral level before it is discharged to drain.
Buffer Tanks
AERCO buffer tanks are ASME certified pressure vessels designed for use with high efficiency, low volume systems that incorporate low-mass condensing boilers. They add thermal mass, dampen fast transitions and minimize boiler cycling that occurs during zero or low domestic load conditions. The AERCO buffer tanks are available in two and four-port (Primary-Secondary) configurations.
Venting Mufflers
AERCO offers 6”, 8”, and 14” exhaust mufflers that are specifically designed with flanged ends to fit directly on the exhaust manifold of Benchmark® Platinum boilers. The flanged-end design allows the muffler to be used with any venting system manufacturer – the only adapter required is an AERCO starter piece at one or both ends of the muffler.
