The smaller of the two measures 720mm (H) x 440mm (W) x 406mm (D) and has a maximum hot water flow rate of 14.5 litres per minute, and the bigger model has a different depth of 474mm and offers Vaillant’s highest ever flow rate of 17.8.

You’ll be given a standard 5-year warranty but have the option to upgrade to a free 7-year warranty as long as the boiler is fitted by a Vaillant Advance installer.

Boiler Energy Efficiency Credentials

This combination boiler by Vaillant is 94% efficient and utilises innovative technology to help you manage your gas consumption and reduce your energy bills. It is an ErP A-rated boiler with a wide modulation range of up to 1:10 and a special Green iQ mode, both of which play their part in maximising efficiency levels and keeping your fuel bills low. You can also add Valliant’s vSMART heating control to the ecoTEC Exclusive to enable this combi to achieve an A+ ErP rating, as well as give yourself the power to control the boiler from your smartphone and other smart devices.

ecoTEC Exclusive Green iQ Combi Technology and Main Advantages

Valliant’s ecoTEC Exclusive features a clear digital display to make boiler management and choosing the right temperature super easy. It also comes with user-friendly controls, all of which are hidden behind a down flap to ensure young children can’t get their hands on buttons and dials.

The boiler has an impressive modulation of 1:10, meaning it can reduce its output to give you the exact amount of power needed to ensure you never waste energy. Put simply, if you require only 20kW, the boiler will adapt itself accordingly. Then there’s the Green iQ mode that optimises running cycles to help lower gas consumption.

In addition to all of those features and benefits, the boiler can work with LPG (liquefied petroleum gas) where required and has its own extra-condense heat exchanger for greater efficiency, performance and energy savings.

Is the Vaillant ecoTEC Exclusive Green iQ Combi the Right Boiler Type and Size for Your Home?

If you live in a medium or large house with multiple bathrooms and want a boiler that boasts incredible hot water performance, the Vaillant ecoTEC Exclusive is a great option. You don’t even need a cold water storage tank or hot water cylinder with this boiler, making it ideal for homes with limited storage space. And since it has a 1:10 modulation ratio, it’s perfectly suitable for a wide range of property types. Having said that, this boiler won’t be the best solution for some larger homes so don’t forget to ask a Gas Safe engineer to assess your heating and hot water usage habits before purchasing this model.
