Weil-McLain® offers the GV90+® high efficiency cast iron boiler for energy efficient, comfort heating in residential applications. The GV90+ features streamlined controls with simple setup, low maintenance and durable design for the long run.

“The GV90+ is designed for homeowners who seek the perfect combination of ideal heating comfort, lower utility bills, peace-of-mind reliability and product longevity,” said Mike Boyd, product manager with Weil-McLain. “The unit features an annual fuel utilization efficiency (AFUE) rating of 91%, exceeding ENERGY STAR® program requirements. Installation of this system also allows homeowners to qualify for a local utility rebates, if available.”

Assembled in Weil-McLain’s state-of-the-art manufacturing facility in Eden, N.C, the unit features a high performance durable cast iron primary heat exchanger made from approximately 70% recycled materials. A corrosion resistant stainless steel condensing secondary heat exchanger recoups heat energy from exhaust normally wasted, to further increase system efficiency.

“The GV90+ has an unsurpassed design in both the primary and secondary heat exchangers, maximizing heat transfer and optimizing boiler efficiency,” said Boyd. “This unique, durable unit is adaptable for most heating demands and effortlessly satisfies 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+ offers a control design allowing easy integration of outdoor reset to take advantage of low water temperatures and improve overall system energy cost savings (GV90+’s optional kit may make homeowners eligible for an additional local utility rebate).

A built-in dual circulator system can accept return water temperatures as low as 60 degrees Fahrenheit with no additional mixing valves, pumps, wiring and installation labor-saving customers hundreds of dollars.

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 controls.

Simple diagnostics significantly reduce troubleshooting time by using flashing LED lights to easily communicate errors.

Other GV90+ key features include:

  • Unique seven pass heat exchanger design maximizes heat transfer
  • Vents with either stainless steel, CPVC or inexpensive PVC material
  • Multiple sidewall or through-the-roof venting options (direct vent, direct exhaust, concentric)
  • Extra-wide waterways allow system debris to flow through easily, limiting scale build-up
  • Easy conversion to propane (kit included)
  • Insulated heavy gauge steel jacket
  • Stainless Steel base and burners
  • Multiple sizes to satisfy every application
