In an effort to keep up with demand, a bourgeoning east-coast microbrewery sought to significantly increase production, but, to do so, it required a more cost-efficient and effective heating process.

Christopher Drew was recently promoted to president and chief operations officer for Burnham Holdings Inc. He assumes the role from Douglas Brossman who, after seven years as president and CEO, will retain his role as chief executive officer. Drew will begin his new role on April 29 at Burnham Holdings’ annual meeting.

The models come with a patented in-house designed and manufactured heat exchanger, low-profile burner, advanced controls, a built-in DHW module, common venting capability up to eight units, cascading capability up to 16 units, and built-in hardware to connect up to three zone pumps without a need for additional external controllers.

This unit meets all market-driven bid specifications and is designed for most heating needs, including applications in schools and other educational facilities, public institutions, health care buildings, offices, hotels, multifamily housing, churches, and more.

The team combined several technologies, such as continuous exterior insulation, energy recovery ventilators, sealed combustion boilers, and individual room thermostat controls, including Danfoss thermostatic radiator valves (TRVs). The result is 90 percent lower energy consumption than comparable buildings — and heating costs below $50 per apartment per year.

They are designed for use in retrofits or new construction in single-family homes, apartments, or condominiums. The units are available in three sizes: 80-, 120-, and 155-MBH input, in both combi or heat only versions.

Designed in-house, it is form-pressed and robotic laser welded to minimize the number of weak points that could be prone to thermal stress and corrosion. Oval shaped tubes within the heat exchanger contain internal turbulators designed to improve both the heat transfer rate and the structural integrity of the assembly.

The units include a corrosion-resistant stainless steel fire-tube heat exchanger and a negative regulation combustion system.

Situated on four acres in a wooded area, the Diamondhead Apartment complex consists of four buildings each with eight apartments. The buildings’ deteriorating heating system was installed when the complex was built in 1989.
