Vaillant ecoTEC Plus 418 (ErP) Open Vent Boiler

The Vaillant ecoTec Plus 418 (ErP) Open Vent Boiler Only is designed for properties with an existing cylinder-based heating system and a separate hot water store. It is a sensible replacement for a conventional boiler, giving homeowners reliable heating without needing to completely redesign the system. This regular boiler is suited to traditional home heating setups where dependable output and straightforward installation matter.

The Vaillant ecoTEC Plus 418 (ErP) Open Vent Boiler is a powerful and efficient heating solution, designed for homes with traditional open-vented systems that require a higher heat output. Combining strong performance with a compact design, this model is an excellent upgrade choice for replacing older boilers while improving overall efficiency and reliability. Despite delivering an 18kW output, the ecoTEC Plus 418 maintains a compact footprint, making it easy to install in cupboards, airing spaces, or utility areas. Its sleek and modern appearance ensures it integrates neatly into your home without taking up unnecessary space, while still providing the heating power needed for larger properties. Ease of use is at the heart of this boiler's design. With simple push-button controls and a clear, easy-to-read display, adjusting settings is straightforward. The built-in diagnostic system provides detailed performance and fault information, making servicing quicker and more efficient for engineers. To ensure reliability all year round, the ecoTEC Plus 418 features built-in two-stage frost protection, helping to protect the system during colder weather. It is also fully compatible with Vaillant's range of accessories and controls, allowing you to tailor your heating system for improved comfort and energy efficiency. With an A-rated ErP heating efficiency, this boiler is designed to reduce energy usage and keep running costs down. It also comes with a standard 5-year warranty, which can be extended up to 10 years when installed by a Vaillant Advance Installer, offering long-term reassurance.
