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.

The boilers utilize a hydrophobic-coated, finned stainless steel heat exchanger to work in concert with the existing high-efficiency cast-iron heat exchanger.
