The Vaillant ecoTEC Plus 940 Combi Storage Boiler is a premium heating and hot water solution, designed for homes that require strong water pressure and high hot water demand. Combining the convenience of a combi boiler with an integrated storage system, it delivers powerful performance while maintaining the efficiency and reliability expected from Vaillant’s latest ecoTEC Plus range.
This model features a refined internal layout, giving engineers easy access to all major components and making installation and servicing quicker and more straightforward. The modern semi-touch interface ensures a smooth user experience, while the guided commissioning wizard simplifies setup for installers. Everyday operation is equally simple, thanks to the clear display and intuitive navigation.
The ecoTEC Plus 940 stands out with its integrated hot water storage, allowing it to deliver high volumes of hot water more quickly than standard combi boilers. This makes it ideal for larger households or properties with multiple bathrooms where demand is higher. At the same time, it retains a familiar footprint, pipe connections, and flue positioning, making it suitable for straightforward upgrades or replacements.
Performance is enhanced through Vaillant’s latest technologies. IoniDETECT continuously monitors combustion, enabling the boiler to operate across a wide modulation range of up to 1:10. This ensures the system runs efficiently by adjusting output to demand, helping to reduce energy consumption and running costs. linBUS technology further improves system performance by providing accurate readings of flow rate and pressure through the internal pump.
Designed with future flexibility in mind, the ecoTEC Plus 940 is hydrogen-ready and can safely operate with up to a 20% hydrogen blend. It is also fully compatible with Vaillant’s range of controls, flues, boiler protection kits, and renewable technologies. In addition, it is smart home ready and can be connected to the myVAILLANT connect internet gateway for app-based control (additional equipment may be required).
