Evergreen

For the owner who seeks heating comfort while maintaining low utility bills and a reduced carbon footprint, the Evergreen stainless steel condensing boiler features an AFUE rating of 95 percent and is designated as Most Efficient by ENERGY STAR. Its design makes installation simple for contractors. The unit features a guided setup wizard, a graphical user interface and 10 heating system presets for setup.

The Evergreen line is now available in six sizes, ranging from 70 to 399 MBH input, accommodating both small and large residential projects, as well as light commercial applications. The units are adaptable for most heating demands, ensuring heating comfort through multiple zones. For the residential and light commercial customer who requires a multiple boiler setup, the Evergreen line can cascade two to eight boilers together, and ZoneStacking up to 24 programmable zones with no external panel required. With this advanced control feature, the Evergreen boiler maintains optimal efficiency through lead-lag rotation and balanced heat loading.

Ultra Series 4

The Ultra Series 4 boilers feature a heat exchanger with nanotechnology coating that works like Ultra Armor, protecting the unit from buildup in the heat exchanger while maintaining high efficiency. The nanotechnology coating repels exhaust residue formation on the heat exchanger surface while preventing acidic condensation penetration, ensuring the unit requires no cleaning for a full five years after installation.

Available in six sizes, the Ultra Series 4 offers quiet operation, ease of set up and control, and comfort with the potential to provide immediate payback in energy savings. The Ultra Series 4 is a good fit for light commercial applications, allowing contractors to pair boilers in sequence to heat larger buildings and control multiple boilers from a single control panel.

GV90+

The GV90+ high efficiency cast iron boiler line is designed for owners who seek the right balance between heating comfort, low utility bills, reliability and product longevity. The unit features streamlined controls with setup ease, and a durable design. The GV90+ offers an AFUE rating of 91 percent, exceeding ENERGY STAR program requirements, and available in four sizes.

The GV90+ is designed with a cast iron primary heat exchanger. A corrosion resistant stainless steel condensing secondary heat exchanger recoups heat energy from exhaust normally wasted, to further increase system efficiency. This unit adapts to satisfy various comfort heating demands, from multiple in-home zones to driveway snow melting and even pool heating. Unlike most traditional cast iron boilers, the GV90+ line allows easy integration of outdoor reset to take advantage of low water temperatures and improve overall system energy cost savings.

AquaBalance Series 2

The AquaBalance Series 2 units feature an energy efficiency of 95 percent and combine the warmth of high-efficiency space heating with the convenience of on-demand domestic hot water in a space-saving package. AquaBalance boilers are ideal for retrofits or new construction in single-family homes, apartments or condominiums. Now available in three sizes (80, 120 and 155 MBH input) in both combi or heat-only versions, the units feature a pleasing design and user-friendly controls, while delivering contractors and homeowners installation ease and worry-free operation.

With the industry’s latest stainless steel, titanium-infused heat exchanger technology, the AquaBalance Series 2 provides advanced condensing technology to deliver efficient space heat and domestic hot water in a compact design that can fit in a closet. The AquaBalance Series 2 boilers were awarded the ENERGY STAR Most Efficient designation to deliver maximum operational cost savings to owners.
