The Vaillant ecoTEC Plus 625 System Boiler is part of Vaillant’s latest range of high-performance boilers, designed to deliver exceptional efficiency, ease of installation, and advanced functionality. With a refined internal layout and improved access to key components, this model makes installation, servicing, and maintenance quicker and more convenient for engineers.
This upgraded ecoTEC Plus model features a modern semi-touch interface, providing a smooth and intuitive user experience. The guided commissioning wizard helps installers complete setup efficiently, while the clear display and simple navigation make day-to-day operation straightforward for homeowners. Retaining the same footprint, pipe connections, and flue positioning as previous models, it’s ideal for hassle-free replacements.
Performance is enhanced with Vaillant’s latest technology. The IoniDETECT system continuously monitors gas combustion, allowing the boiler to operate across a wide modulation range of up to 1:10. This ensures the boiler only uses the energy required, improving efficiency and reducing running costs. In addition, linBUS technology delivers more accurate readings of flow rate and pressure via the internal pump, helping to optimise overall system performance.
Designed with flexibility in mind, the ecoTEC Plus 625 supports automatic LPG conversion on most outputs, completed quickly through the interface without the need for extra parts. It is also hydrogen-ready, meaning it can safely operate with up to a 20% hydrogen blend, helping to future-proof your heating system.
Fully compatible with Vaillant’s range of controls, flues, boiler protection kits, and renewable technologies, this boiler can be tailored to suit a wide range of installations. It is also smart home ready, working with the myVAILLANT connect internet gateway for app-based control and remote access (additional equipment may be required).
