John Miller, senior product manager with Weil-McLain, stated:

The SVF boiler line was developed with the contractor in mind and utilizing extensive market research and testing to help shape design and functionality. The result is firetube performance, perfected. The new SVF showcases the quality, durability, serviceability and innovation that contractors have come to expect from Weil-McLain, and demonstrates our commitment to industry-leading hydronic heating performance.

Available in 750 and 1100 models, the SVF line features a clover-shaped stainless-steel fire tube heat exchanger for best-in-class corrosion resistance, a new and bold exterior look, and simple, user-friendly controls to make installation and operation easy. With superior thermal efficiencies, the SVF line offers cost savings and energy efficiencies that could allow owners to qualify for local utility rebates, if available.

The unit meets all market-driven bid specifications, and is designed for most heating needs including applications in schools and other educational facilities, public institutions, health-care buildings, offices, hotels, multifamily, churches and more.

Time-saving installation features include heavy-duty roller casters for improved maneuverability in confined spaces, industrial-grade leveling legs, an end-shot burner design requiring only 18 inches overhead space, and the advanced Unity control set-up wizard.

Miller added:

The Unity Controller is designed to reduce installation and set-up time for contractors, simplify boiler system design for specifying engineers, and improve control interface commonality and communication across the entire Weil-McLain high-efficiency boiler line.

For ease of service, the SVF features a hinged cover plate with quick access to the burner and fire tubes for simple heat exchanger wash-down with no need for additional disassembly, and an open back panel design with no side access required for service. The unit also features a removable and replaceable condensate base.

Other key features include:

  • 70 to 2,0000 MBH compatibility
  • 160 psi working pressure
  • Natural gas or propane fuel options
  • Modbus communication with BACet/Lonworks compatibility
  • Low NOX
  • Full line of venting options

The SVF also is ideal for applications calling for a cast iron boiler complement, and joins the Weil-McLain family of boilers that includes the industry’s widest selection of high-efficiency gas and oil-fired boilers for residential, commercial and institutional needs.
