This is the least powerful combi in the ecoTEC plus range. Great for smaller properties with lower hot water demand.

You can get a 10-year warranty with this boiler.

Vaillant ecoTEC Plus 835 review 

If you have a medium-sized home with relatively high hot water demand and 4 bedrooms then you may want to consider the energy-efficient ecoTEC Plus 835 combi. This higher-powered boiler will ensure that you can have instant hot water at the perfect temperature to even the furthest away taps and radiators in a house with up to 20 radiators. This combi has a great flow rate of 14.3 litres per minute so it is more than capable of providing hot water to multiple outlets. You can get a 10-year warranty with this boiler.

Vaillant ecoTEC Plus 838 review

The most powerful ecoTEC plus is the 838 combi. This excellent combi boiler is better for larger homes, and with a high flow rate of 15.9 litres per minute, it can easily provide 2 taps or outlets at the same time with instant hot water. If you are looking for a powerful combi boiler then this may be the one you are looking for. It is slightly bigger than the others in the range but packs a real punch all whilst being energy efficient! You can get a 10-year warranty with this boiler.
