Product Description

The EcoTec Exclusive Green iQ 835 is a combi gas boiler and is Vaillant's first ever boiler built with the power of green IQ technology. This Vaillant boiler has smart technology features and provides excellent performance.

How efficient is the ecoTEC Exclusive Green IQ 835?

The green IQ technology helps to make this a highly efficient boiler, as shown by the 94% efficiency rating and ErP A-rating for heat and hot water. This unit has been fitted with an extra-condense stainless steel heat exchanger which greatly increases efficiency.

Is the output rating suitable for my home?

This model has a central heating output of 26.4 kW makes this Vaillant combi boiler well suited to larger properties with up to 20 radiators.

Does the Vaillant Green IQ range include any other options?

In addition to the IQ 835, there's also a 43 kW combi boiler for even larger properties. Should you have higher demand for domestic hot water then there's the Green IQ 627 which is a system boiler so stores hot water in a hot water cylinder.

Is a combi boiler suitable for my property

Combi boilers have quickly become the most popular boiler type installed in homes across the UK. This is largely because of their space-saving qualities as they don't require any additional cylinders or tanks. They're great for smaller properties with a low to moderate demand for hot water but should you have more than 2 bathrooms, a system boiler could be the better option.

This Green IQ 835 manages the consumption and output to keep the components all running with its peak performance, making it a low maintenance boiler that you can rely on. It comes with a wide modulation range of up to 1:10, giving it the ability to adapt perfectly to all systems in all situations and helping to keep your fuel bills down.

It also has a green IQ mode which helps to optimise the running cycle (resulting in even lower gas consumption). Green IQ mode also means that the unit 85% recyclable when the time comes for a boiler replacement.
