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. 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.
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.
