BENEFITS THAT MAKE IT LAST
MAXIMUM HEAT
EXCHANGER PERFORMANCE
■ Durable cast iron primary heat exchanger.
■ Corrosion resistant stainless steel condensing secondary heat exchanger, increases efficiency by recouping heat energy from exhaust normally wasted when vented from the building.
RELIABLE BOILER DESIGN
■ Unlike most high-efficiency boilers in the industry, the Weil-McLain GV90+ has extrawide waterways (over 2”) 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.
PROVEN CONTROL STRATEGY
■ The control platform features error-proof, labeled, snap in connections. Tested at over 100,000 cycles, and boasting a failure rate of less than 1% over 20 years.
■ Unlike traditional cast iron boilers, the GV90+ offers a unique control design allowing easy integration of outdoor reset to take advantage of low water temperatures and improve overall system energy cost savings.
SMART CIRCULATOR STRATEGY
■ Built-in dual circulator strategy provides boiler protection - it can accept low return water temperatures (down to 60o F) 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.
