Weil-mclain 672619195233 GV90+ Series Gas Fired Cast-iron Water Boiler 175000 Btu/hr 91% Afue

Product Description

The Weil-McLain 672619195233 is a high-efficiency, cast-iron gas fired water boiler from the GV90+ Series, model GV90+6. It is built for residential and light commercial hydronic heating systems where reliability and fuel efficiency are priorities. HVAC technicians and heating contractors choose this boiler when they need a proven, durable unit that delivers consistent hot water heat across a wide range of heating loads. The GV90+ Series has a long-standing reputation in the trade for its robust cast-iron heat exchanger, which resists corrosion and holds up through years of daily cycling. Cast iron also retains heat efficiently, making it a preferred material for high-demand boiler applications. This unit carries a 91 percent AFUE rating, meaning it converts 91 percent of fuel into usable heat. That level of efficiency helps reduce fuel costs compared to standard efficiency boilers, which is a key selling point for homeowners and building managers. The boiler produces 175000 Btu/hr gross input and delivers a net BTU rating of 140000 Btu/hr, making it well suited for larger homes or buildings with significant heating demands. It operates on both natural gas and liquid propane, giving installers flexibility depending on the fuel source available at the job site. The gas connection is 1/2 inch and supply and return connections are 1 inch. Ignition is handled by a hot surface igniter, which is more reliable than standing pilot systems and eliminates the need for a continuously burning flame. Venting is handled through a 3 inch vent diameter direct exhaust and direct vent configuration. This allows for flexible installation options, including sealed combustion setups that draw combustion air directly from outside the structure. The unit holds 6.9 gallons of water and measures 24-5/8 inches wide, 37-3/4 inches deep, and 30-3/4 inches tall. These dimensions make it compatible with most mechanical room installations where a full-size residential boiler is required.
