Vaillant ecoTEC Exclusive Green iQ System Boilers

You can expect to pay on average around £1,310.40 for the Vaillant ecoTEC Exclusive Green iQ System Boiler, which includes VAT and excludes fitting fees.

EcoTEC Exclusive Green IQ 835 Combi Gas Boiler

Labelled by Vaillant as the best in the business, the ecoTEC Exclusive System is a condensing wall mounted boiler that requires a cylinder for storing your hot water.

It measures 720mm (H) x 400mm (W) x 338mm (D), has a heating output of 27kW and features an impressive range of smart technologies. You may also be interested to know that it has the Green iQ mark, which means the boiler is not only extremely energy efficient and eco-friendly but also fully equipped to enable you to take advantage of app-based heating controls.

Perfect for homes with more than 1 bathroom, this appliance will cost about £1,310.40 and comes with a standard 5-year warranty. But if you’re happy to get the boiler installed by a Vaillant Advance installer, you’ll receive a free upgraded warranty that covers you for 7 years.

Boiler Energy Efficiency Credentials

With an official ErP efficiency rating of 94%, the ecoTEC Exclusive Green iQ System is an A rated boiler for both heating and hot water efficiency. It boasts an incredible modulation range of 1:10 to ensure the boiler never uses more energy than required, helping to reduce the cost of your fuel bills. And thanks to the included Green iQ mode, the gas consumption rate is reduced even more. If you like the idea of boosting the efficiency rating to A+ for better energy and cost savings, you can use Vaillant’s optional vSMART intelligent room control with app.

ecoTEC Exclusive Green iQ System Technology and Main Advantages

The ecoTEC Exclusive System is the first of Valliant’s boilers to feature Green iQ technology to make the appliance green, intelligent and networked. This basically means that the boiler guarantees a high degree of recyclability, optimal efficiency levels and the lowest running costs.

It features a wide modulation range of up to 1:10, meaning the boiler can adapt to every situation and reduce its output to deliver the precise level of heat so it never wastes energy. The ecoTEC Exclusive System also has an extra-condense heat exchanger to maximise efficiency levels and reduce your fuel bills even more.

Other noteworthy features include an integrated diverter valve to improve comfort and ease of installation, a clear digital display for simple boiler management and family-friendly concealed user controls. We should mention that the boiler also has the seal of approval from Quiet Mark, making it a great, quiet choice if you plan to keep it in or near a busy room.

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

Since the boiler has an output of 27kW, it is best suited to medium and large properties in need of a constant supply of hot water to multiple taps or showers at the same time. So if heating and hot water demand are greater in your home, this could be the boiler for you. Just remember, this boiler does require a hot water cylinder but does not need a cold water tank in the loft. To be on the safe side, we suggest you always ask a Gas Safe engineer to help you determine whether this boiler will satisfy the needs of your household.

Our Honest Opinion of the Vaillant ecoTEC Exclusive Green iQ System

We can see why this boiler is called ‘Exclusive’ because that’s precisely what it is, especially since it is one of only two Vaillant models that carry the Green iQ mark. To achieve this status, the boiler must display a proven build quality and incorporate smart connectivity solutions, along with everything else we mentioned above.

The ecoTEC Exclusive Green iQ System is smart in other ways too, such as the way it provides only the required level of heat and the fact that it’s compatible with optional energy-saving controls. It can even keep gas consumption low, reduce your bills and be recycled at the end of its life.

It’s also good to see that Vaillant is giving away a free warranty upgrade when the boiler is fitted by an Advance installer to give consumers confidence in the quality of this system. A 10-year warranty is available as well but it isn’t free so you will need to pay extra for this. And whilst it isn’t the cheapest system boiler on the market, we do think you get a lot for your money with this offering by Vaillant.

Advice on Boiler Quotes and Gas Safe Engineers

If you want to find the best deal on the Vaillant ecoTEC Exclusive Green iQ System Boiler, you should obtain at least a couple of quotes from local installers and compare them with a couple from national installers. When liaising with engineers, ask for a fixed price on the boiler and installation work to keep yourself protected from hidden fees. You also need to be aware that it is now a legal requirement for your chosen installer to be Gas Safe registered to confirm they are legally allowed to work on your new boiler. For peace of mind, simply ask to view their ID card or run a search at the Gas Safe Register website.
