It features a long-lasting fire tube heat exchanger and is available in combi versions with response time and domestic hot water (DHW) output designed to meet the demanding needs of residential replacement applications. ECO Tec is easy to install, use and service, operates whisper quiet, and is among the most energy-efficient residential boilers available today.

Weil-McLain’s new ECO Tec boiler meets nearly all residential application needs, including multi-zone and combi applications.

ECO Tec is available in four heat-only sizes ranging from 80 to 199 MBH. The combi versions are available in three sizes—110, 150 and 199 MBH—with hot water output up to 5.4 gallons per minute (GPM) and features Weil-McLain’s advanced ECO BOOST technology to provide rapid DHW response. ECO Tec also includes built-in zone control, connects up to four thermostat inputs and features an easy-to-use setup wizard and heating system presets.

Featuring a 95 percent AFUE rating, ECO Tec is among the highest energy efficient residential boilers in the industry. ECO Tec achieved the “Most Efficient” rating level from Energy Star in 2020 and is rated to deliver maximum operational cost savings to homeowners and provide qualification for local utility rebates, if available.

The unit’s durable stainless steel fire tube heat exchanger features a vertical orientation for “self-rinsing” during operation, and a polypropylene condensate-collector base that provides better corrosion resistance than traditional stainless steel, helping to ensure a long service life. A sound suppressing air silencer on the heat exchanger provides whisper quiet operation.

ECO Tec is designed for easy maintenance and service with a spacious cabinet that allows for full access to internal components, common parts for all unit sizes and the easy-to-use control touch screen display.

Other key features of the ECO Tec include:

  • Up to 10:1 turndown ratio that self-adjusts to minimize fuel usage
  • Low NOx emission certified
  • NSF/ANSI 372 certified domestic hot water components
  • Built-in energy-saving ECM circulator to conserve energy
  • Built-in zone control that can operate up to 4 circulators (plus internal)
  • Natural or propane gas capable
  • Multiple venting options for different home styles and buildings

The ECO Tec’s modern design makes it easy to transport, deliver and install and offers versatile placement options with included and optional kits. Its wall mount design frees up valuable floor space, while its optional pedestal can be used for floor standing installations.

All units are tested and certified to the industry’s highest standards and include a warranty of up to 12 years on the heat exchanger and up to five years on parts with registration (two years on parts without registration).
