Weil McLain takes condensing boiler technology to a higher level of performance. The Ultra Series 4 features a state of the art heat
exchanger with nanotechnology coating that works like "Ultra Armor", reducing build up in the heat exchanger while maintaining high
efficiency. Nanotechnology is a heat exchanger coating that combines anti-adhesive and anti-corrosion properties, which protects the heat
exchanger from corrosion and combustion residue build up. In conventional systems, aggressive exhaust particles can attach to the surface
and cause heat exchangers to corrode. Heat transfer is then reduced and the heating system's energy efficiency decreases. With
nanotechnology properties, biofilm formation is inhibited and allows residues to be easily carried out of the heat exchanger before they
obstruct the flueways. In addition, Ultra Series 4 has an advanced condensate management system that incorporates polypropylene piping to
further reduce the impact of condensate. Thanks to our nano-coated heat exchanger, the Ultra Series 4 requires no cleaning for a full five
years after installation. When it's time to clean, a simple rinsing of the coated heat exchanger with water does the trick. The Ultra Series 4 is
an ideal choice for single family residential applications. Homeowners will appreciate its quiet operation, ease of set up and control, and
unmatched comfort while providing immediate payback in energy savings. For light commercial applications, the Ultra Series 4 lets
contractors pair boilers in sequence to heat larger buildings. And, it allows you to control multiple boilers from a single control panel. Back-lit
LCD display and simple programming buttons make entering and receiving information easy. The homeowner has the ability to view current
boiler status, check water and outdoor temperatures, review boiler maintenance schedule and view installing contractor contact information.

Keeping your home comfortable and warm is a high priority-but it doesn't have to come at a high cost. Whether you heat by
baseboard, panel radiators, hydro-air systems or radiant flooring, our advanced heating systems will provide many years of
exceptional comfort and savings. A conventional boiler heats and circulates water at only one temperature; typically 170 to 180
degrees until the thermostat signals it to stop. A Buderus boiler, especially when paired with the Logamatic control, eliminates
these room temperature swings by adjusting the boiler water temperature to the current conditions, saving fuel while keeping you
warm and comfortable. Sections are assembled with beveled, surface profiled push nipples for long, trouble free watertight
operation. Special sealing compounds provide a gas tight seal for safe and efficient operation.

The Weil McLain GV90+ boiler has a durable cast iron primary heat exchanger that extends product life - it is not uncommon for cast iron
boilers to last in excess of 40 years. A corrosion resistant stainless steel condensing secondary heat exchanger increases efficiency up to
5% by recouping heat energy from exhaust normally wasted when vented from the building. The extra heat energy is then added and
circulated through the baseboard or radiators to efficiently heat the home. Unlike most high efficiency boilers in the industry, the Weil
McLain GV90+ has extra-wide waterways (over 2 inches) allowing sludge and debris, often present in older systems, to flow through easily.
This limits scale build up, which reduces boiler efficiency, performance and can lead to premature boiler failure. Down fired, counter flow
boiler design improves boiler efficiency. The GV90+ offers 5 pass design in the primary heat exchanger and 2 pass design in the secondary
heat exchanger maximizing heat transfer and optimizing boiler efficiency. Built in dual circulator strategy provides boiler protection - it can
accept low return water temperatures (down to 60 degrees) with no additional mixing valves, pumps, wiring and installation labor. The
lower water temperature also allows homeowners the flexibility to add radiant heating for kitchens, baths or other living spaces without the
added cost of special return temperature controls.
