Product Information

Vaillant ecoTEC Plus 826 Combi Boiler

The Vaillant ecoTEC Plus 826 Combi Boiler is a modern, high-efficiency heating and hot water solution, designed to deliver reliable performance with the latest smart technology. As part of Vaillant’s newest ecoTEC Plus range, it features a refined internal layout that provides easy access to all major components, making installation, servicing, and maintenance quicker and more straightforward. This updated model introduces a sleek semi-touch interface, offering 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 use easy for homeowners. With its familiar footprint, pipe connections, and flue positioning, it’s also ideal for straightforward replacements of older Vaillant boilers. Performance is enhanced through advanced innovation. IoniDETECT technology continuously monitors gas combustion, allowing the boiler to operate across a wide modulation range of up to 1:10. This ensures the system only uses the energy required, improving efficiency and helping to reduce running costs. linBUS technology further enhances performance by delivering more accurate readings of flow rate and pressure through the internal pump. The ecoTEC Plus 826 is designed with flexibility and future-proofing in mind. It supports automatic LPG conversion on most outputs, completed quickly via the interface without the need for additional components. It is also hydrogen-ready, meaning it can safely operate with up to a 20% hydrogen blend, helping prepare your home for future energy standards. Fully compatible with Vaillant’s range of controls, flues, boiler protection kits, and renewable technologies, this combi boiler can be tailored to suit a wide range 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).

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
