To meet demand for a smaller, lighter, high-efficiency, stainless steel condensing boiler that can be installed quickly and used immediately, we designed the Shadow. The wall-mounted Shadow is a gas-fired, condensing boiler that pairs high efficiency with impressive ease of installation and operation. It is available in five sizes – 80, 100, 120, 150 and 180 MBH, with up to 95% AFUE.

The compact and lightweight design includes a modulating burner with a 5-to-1 turndown ratio and an LCD display, offering a clean and simple boiler that is easy to operate.
