Product Description

The ecoTEC exclusive green IQ 843 is a combi gas boiler that is condensing and wall mounted. This boiler is manufactured by Vaillant and is an extremely reliable unit with an output of 43kW.

How efficient is the Green IQ 843?

The Green IQ range has been designed by Vaillant with efficiency in mind. They boast an efficiency of 94% and ErP A-rating for heating and hot water, which means that this boiler could help to significantly lower your energy.

Is the output rating suitable for my home?

A central heating output of 36 kW means that the Vaillant Green IQ 843 is well suited to properties with up to 20 radiators.

Are any other options available in the Vaillant Green IQ range?

The Vaillant Green IQ range includes two combi boilers and a system boiler. In addition to this 43 kW model, there's also a 35 kW combi and 27 kW system boiler.

Is a combi boiler suitable for my home?

Combi boilers are single cost effective units that provide heating and hot water on demand so there's no need for any external tanks or cylinders. While this is great news for smaller homes or properties with limited room, it does mean that they're unable to meet really high demand for central heating and hot water.

How long is the warranty period?

Vaillant have attached a 5 year warranty as standard to their Green IQ boilers but this can be extended to 7-10 years when installed by a Vaillant Advance installer.

What are the key features of the Green IQ 843?

This is Vaillant's first ever boiler with the power of green IQ technology, combining a complete range of smart technologies and features, so you can be sure that you are getting a highly efficient boiler. Great performance is guaranteed as it;s able to intelligently manage consumption and output, keeping its components running at peak performance for longer, as well as providing a low maintenance solution that you are able to rely on.

It comes with extra condense technology and a single system boiler, including an integrated diverter valve, which is the first ever in Vaillant history. It also comes with a wide modulation range of up to 1:10 helping it to adapt to all systems in every situation, ensuring you have the lowest fuel bills and a high flow rate of 17.8 l/min. This boiler always reaches optimal combustion with low emissions, this is done through its self-adaptive system that can automatically adjust to all types of gas. As well as all these benefits it also comes with an extra condense heat exchanger - taking the combi boiler efficiency to the next level and almost eliminating plume in DHW mode.

This unit optimises running cycles to give you the best results in lower gas consumption, and when having the full run of the boiler it is is able to be recycled. It is compatible with Vaillants smart heating control to give you even more control and reliability.

How big is the Vaillant Green IQ 843?

Vaillant have designed the Green IQ 843 for wall-mounted installation and has dimensions of 720 x 440 x 474mm (HxWxD).
