Description
Burnham's SCG boilers offer a unique combination of high efficiency and value to homeowners. SCG sealed combustion boilers utilize stainless steel vent pipe to direct the flue products out of the building. This eliminates the need to install a liner in an existing chimney - which is often a major expense when replacing an older boiler.

SCG series boilers are simple to install, and require very little service and maintenance - especially compared to higher-efficiency condensing boilers. This can save homeowners hundreds of dollars in up-front installation costs, as well as several hundred dollars a year in maintenance and tune-ups. Factoring in installation, annual service, and fuel usage - over time the operating costs of the SCG may be well below those of condensing boilers. While low temperature radiant heat systems are becoming more popular in newer buildings, many still utilize baseboard heat, convectors, air handlers. & indirect water heaters - which generally require higher water temperatures. Cast iron boilers are the best choice for these applications. The SCG delivers the winning combination of efficiency and durability in high-temp heating applications.

Reliable Cast Iron Heat Exchanger
SCG boilers have rugged cast iron heat exchanger sections that are poured in Burnham's own state-of-the-art foundry in Zanesville, Ohio. This means that Burnham is able to control the quality of this vital component from the time that it's poured to the time that it's installed and tested in the boiler. The heat exchanger itself is designed for efficiency. Round pins on the outside of the exchanger increase the surface area which increases heat transfer. Inside, dimpled waterways promote turbulence as water flows through the castings. This helps to thoroughly mix cooler return water with the water inside the heat exchanger. As a result, SCG boilers are more resistant to thermal shock and condensation than other comparable boilers. Steel nipples are used to join sections together. This vital component is impervious to petroleum-based chemicals (like antifreeze) which can break down the rubber gaskets that are used by competitors.

Safety Without Compromise
Burnham's reputation for building safe products is an ongoing commitment that is taken very seriously. Many additional safety features have been built into the SCG boiler:
  • Blocked Vent Switch: Safely shuts the boiler down if a chimney or vent blockage is detected.
  • Flame roll-out switch: If an internal flueway restriction is detected, this device will automatically stop the flow of gas to prevent combustion gases from seeping into the home.
  • Concealed Controls: All boiler controls are safely hidden under the jacket to prevent damage & tampering.
