Weil-McLain 383-800-004 ECO 110 Input MBtu 95% AFUE Combustion Natural Gas Water Boiler - Direct Vent

Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing long-lasting heating solutions is seen in every boiler they make. The ECO hot water boiler is an ideal blend of efficiency and value. A remarkable 95% AFUE sets the ECO 110 apart from other boilers. This efficiency is possible in such a small package thanks to condensing technology and a modulating burner. Condensing boilers trap gas that escapes traditional boilers and reuse the heat within. Modulation reduces unnecessary fuel use by scaling the burner output to match your heating demands. The ECO includes a control that is both easy to use and easy to read. Both the ECO and the control mount on the wall for convenience and to save space. Weil-McLain's ECO brings efficiency and flexibility to the forefront in a package that suits any space.

• Fire Tube Heat Exchanger
• The ECO forgoes a typical heat exchanger for a fire tube heat exchanger. Fire tube heat exchangers allow for larger water content than traditional heat exchangers, which reduces short cycling and temperature fluctuations.
Outdoor Reset Control
• An outdoor reset sensor is included with every ECO boiler. This sensor allows your boiler temperature to be adjusted relative to the temperature outside, eliminating excess energy use and guaranteeing comfort.
Easy Installation & Maintenance
• The ECO's low profile and wall mounting mean that it can be installed almost anywhere. The internal components are situated for quick maintenance, and removable control terminal blocks simplify wiring.
