Weil-McLain says it is now offering its most advanced high-efficiency condensing boiler. The new 95% AFUE Evergreen boiler is designed with simple controls and flexible functionality for multiple applications. The unit is adaptable for most heating needs including light commercial or large residential applications and for single or multi-boiler installations. The unit features a guided setup wizard, an easy to understand graphical user interface, simple controls, and 10 heating system presets for quick setup, according to company officials.

For light commercial customers who require a multiple boiler setup, the Evergreen offers the ability to cascade eight boilers together and ZoneStacking up to 24 programmable zones with no external panel required. ZoneStacking reduces the installation costs and time while increasing reliability. With this control feature, the Evergreen boiler maintains optimal efficiency through lead-lag rotation and balanced heat loading.

In commercial applications, optimal energy efficiency yields reduce energy costs with up to 96.5% combustion efficiency. The SmartSequencing feature maximizes energy across all boilers on a system, reducing energy costs. The unit also is certified as low NOx by the South Coast Air Quality Management District (SCAQMD) with less than 20 ppm.
