The Vaillant ecoTEC Plus 615 System Boiler is part of Vaillant’s latest generation of high-performance boilers, designed to deliver improved efficiency, easier installation, and enhanced usability. With a refined internal layout and better access to key components, this model makes both installation and servicing quicker and more convenient for engineers.
This updated ecoTEC Plus model features a modern semi-touch interface, making setup simple and intuitive. The guided commissioning wizard walks installers through the process step-by-step, while the clear and user-friendly navigation ensures straightforward day-to-day operation. Retaining the familiar Vaillant footprint, including the same dimensions, flue position, and pipe connections, it’s also ideal for hassle-free like-for-like replacements.
Performance is enhanced through Vaillant’s latest innovations. IoniDETECT technology continuously monitors combustion, allowing the boiler to operate across a wider modulation range of up to 1:10. This ensures the boiler only uses the energy it needs, improving efficiency and helping to reduce running costs. In addition, linBUS technology provides more accurate monitoring of flow rate and pressure via the internal pump, optimising system performance.
The ecoTEC Plus 615 is built for flexibility and future readiness. It offers automatic LPG conversion on most outputs without requiring additional parts, making installation more adaptable. It’s also hydrogen-ready, meaning it can safely operate with up to a 20% hydrogen blend, helping to future-proof your heating system as energy standards evolve.
Fully compatible with Vaillant’s range of controls, flues, boiler protection kits, and renewable technologies, this boiler can be tailored to suit a wide variety of heating systems. It’s also smart home ready, working with the myVAILLANT connect internet gateway for app-based control and remote access (additional equipment may be required).
