Weil-mclain 672619195226 GV90+ Series Gas Fired Cast-iron Water Boiler 140000 Btu/hr 91.4% Afue Model GV90+5

Product Description

The Weil-McLain 672619195226 is a high-efficiency gas-fired hot water boiler built on the proven GV90+ platform. Designed for residential and light commercial heating applications, this cast-iron boiler delivers 140,000 Btu/hr gross input and a net BTU rating of 113,000 Btu/hr, making it well suited for larger homes and buildings with substantial heat loads. The unit achieves an AFUE rating of 91.4 percent, meaning it converts more than nine out of every ten units of fuel into usable heat energy. That level of efficiency translates directly into lower fuel costs and reduced energy waste over the heating season. HVAC technicians and heating contractors trust the GV90+ series for its reliable cast-iron heat exchanger, which holds up well against thermal stress and provides long service life when maintained correctly. The boiler runs on either natural gas or liquid propane, giving installers flexibility across different job sites. Hot surface ignition eliminates the need for a standing pilot light, reducing standby fuel consumption and improving reliability in cold-start conditions. The unit supports both direct vent and direct exhaust configurations, allowing venting through a 3-inch diameter vent pipe. This flexibility simplifies installation in retrofit and new construction projects alike. The gas connection is 1/2 inch and the supply and return connections are 1 inch, which are standard sizes for residential hydronic systems. The boiler has a water capacity of 6 gallons and dimensions of 24-5/8 inches wide by 37-3/4 inches deep by 30-3/4 inches tall. The GV90+5 model designation identifies this unit within the GV90+ series lineup. Heating professionals working on high-efficiency boiler replacements, hydronic heating systems, and forced hot water heating upgrades will find this unit a dependable choice.
