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.

Weil McLain Aqua Plus operates as a zone to the boiler, reducing fuel consumption. The tightly wound coil provides a faster recovery
than direct fired water heaters and typically will lose only 0.5 degree per hour. There are no additional exhaust flues, or fuel piping to
consider. The boiler operates less frequently than with other water heating types, resulting in higher efficiencies, and delivers superior
first hour gallons per minute of domestic hot water.
