This floor-mounted unit delivers an input capacity of 199,000 Btu\/hr, making it well-suited for larger buildings, multi-unit properties, and demanding hydronic heating systems. With a 95 percent AFUE rating, this boiler converts nearly all fuel into usable heat, helping reduce energy costs over the life of the equipment. HVAC technicians and mechanical contractors rely on high-AFUE boilers like this one to meet modern energy codes and deliver consistent comfort in cold climates. The direct spark ignition system eliminates the need for a standing pilot light, improving fuel efficiency and simplifying maintenance. Ignition occurs automatically when the system calls for heat, reducing gas consumption during standby periods. The unit vents through a 3-inch vent pipe, which is compatible with standard venting configurations used in residential and light commercial installations. At 47.75 inches tall, this floor-mounted boiler fits into mechanical rooms and utility spaces where wall mounting is not practical. Floor mounting also provides added stability for a unit of this size and input rating. The boiler is designed for natural gas supply and is not rated as Ultra Low NOx, which is an important consideration for installations in regions with strict air quality regulations. HVAC professionals should verify local emissions requirements before installation. This unit is a strong choice for hydronic heating, radiant floor systems, and combination space and water heating applications. Lochinvar is a well-known manufacturer in the boiler and water heating industry, and the 100361998 reflects their standard for durable, efficient heating equipment built for trade installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e199,000 Btu\/hr input capacity supports large-scale heating loads in residential and commercial settings\u003c\/li\u003e\n\u003cli\u003e95 percent AFUE rating delivers high fuel efficiency and helps meet modern energy code requirements\u003c\/li\u003e\n\u003cli\u003eDirect spark ignition eliminates standing pilot light, reducing gas waste and simplifying service calls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Lochinvar 100361998 combines a 95 percent AFUE rating with a high-output 199,000 Btu\/hr input and direct spark ignition in a floor-mounted natural gas boiler.
