B85 + B120 + B160

Condensing Boiler

Glow Brand ASME certified condensing boilers for heating are ultra-efficient and compactly designed, with an AFUE rating of 95%. These units are fully modulating at 10 to 1. PVC 2 inch venting up to 100 feet.


The B85, B120 and B160 are built on experience, and incorporate the latest technological know-how to produce space heating.

Each unit has an efficient and compact design, allowing for ease of installation in both new construction and retrofit applications.

The units operate through simplified controls and features, are energy efficient and environmentally friendly.

Units are available in different capacities and burner modulation affording flexibility in application while meeting varying needs for space heating.

The B85, B120 and B160 are designed for compatibility with a wide choice of accessories and can be used for space heating with air handlers and in-floor heating. Can also be used for domestic hot water through an indirect storage tank.

Glow Brand™ condensing boiler can operate with multiple types of heating systems: hydronic systems incorporating radiators, fan coils or in-floor heating, while maintaining high efficiency levels and comfort.

Each includes an advanced self-diagnostic system providing the user with a simple way to set and verify equipment operation on a back-lit display. Diagnostics are easily identified through symbols.
