Manufactured by Vaillant, the ecoTEC High Output System comes in 46kW and 65kW outputs and can operate alone or be installed in cascade (when multiple units are connected).

This condensing wall mounted boiler measures 800mm (H) x 480mm (W) x 450mm (D) and is designed to be fitted alongside a hot water storage cylinder. As most of the key components are built into the unit, installation is easier, quicker and neater.

Ideal for large homes and commercial properties, the ecoTEC System comes with a standard 5-year warranty and typically costs between £2,177.78 and £2,799.15.

Boiler Energy Efficiency Credentials

This high-performance system boiler has an ErP efficiency rating of over 95% and is considered an A rated appliance. If you don’t already have a hot water cylinder or are looking to upgrade your existing one, the boiler can be installed with a Vaillant uniSTOR cylinder to minimise heat loss and lower running costs. The ecoTEC System is also compatible with optional wired and wireless weather compensators, which can help to increase levels of comfort and running cost savings.

ecoTEC High Output System Technology and Main Advantages

The high output ecoTEC System boasts a whole host of built-in features, such as a high-quality stainless steel heat exchanger to provide adequate protection from oxidation and corrosion. To make installation easier, this boiler has a pump and integrated connection for an expansion vessel.

Vaillant’s ecoTEC System includes built-in energy saving two-stage frost protection so that the boiler always performs at its best all year round, as well as a fully modulating low NOx burner to help lower NOx emissions. In addition to these functions and parts, the boiler is equipped with an air separator with auto vent and filter, push-fit flue system and other flue options.

By allowing your engineer easy access to all of the components, repairs and servicing can be kept simple and straightforward. The appliance also has a clear backlit display to provide your engineer with the correct status and diagnostic information and to ensure you can you manage the boiler with ease.

Is the ecoTEC High Output System the Right Boiler Type and Size for Your Home?

Available in high outputs of 46kW and 65kW, the ecoTEC System is specifically designed for commercial applications and larger homes with two or more bathrooms. You can use the boiler as it comes or link multiple units to allow for cascading operation and to provide a higher overall output. So, if you have larger heating and hot water needs, this boiler is the perfect solution. We should also mention that this model does not require a feed and expansion tank in the loft, making it ideal if you have little or no loft space. However, this boiler won’t be suitable for all large properties, and you must always ask a Gas Safe engineer to help you determine the right model for you and your home.
