Perfect for Traditional Heating Systems

The ecoTEC Plus 415 is specifically designed for homes that use a traditional open-vented heating system, working alongside a separate hot water cylinder and cold water storage tank.

Its intelligent burner modulation automatically adjusts the boiler's output according to demand, helping to improve efficiency, reduce gas consumption, and maintain a comfortable indoor temperature throughout the year. The heating output ranges from approximately 4.7kW to 15.9kW in condensing mode.

Compact Design

The ecoTEC Plus 415 has been engineered to fit neatly into a wide range of installation spaces while remaining easy to maintain.
