How efficient is the Vaillant ecoTEC Plus 435?

Vaillant ecoTEC Plus boilers are highly efficient condensing units that could help to lower your energy bills. The 435 model has an efficiency rating of 93% and ErP A-rating for heat.

Is the output rating suitable for my home?

A central heating output rating of 35.3 kW makes this the most powerful boiler in the range and is best suited to homes with around 20 radiators.

What options are available in the ecoTEC Plus range?

If the ecoTEC Plus 435 is too powerful for the heating demands of your home then smaller outputs of 12.3 kW, 15.1 kW, 18.3 kW, 24.6 kW and 30.5 kW are also available.

Is a regular boiler suitable for my home?

Regular boilers are most commonly found in older traditional properties. This is because they need to be installed as part of a heating system that also includes tanks in the loft and a hot water cylinder. Replacing a combi or system boiler with a regular boiler can be an expensive and lengthy process. So, a regular boiler is the best option for homes looking for a like-for-like boiler replacement.

How long is the warranty period?

To see that you’re well covered after the installation of an ecoTEC Plus 435, Vaillant have included a 5 year warranty as standard. This can be extended to 7 or 10 years when installed by a Vaillant Advance Installer.

What are the key features of the ecoTEC Plus 435?

Key features of the ecoTEC Plus include a wide modulation range of 1:6 to minimise fuel usage and maximise efficiency, full compatibility with Vaillant controls and two-stage frost protection to keep loft and garage installations running all year round.

How big is the ecoTEC Plus 435?

Thanks to compact dimensions of 600x375x320mm (HxWxD) and lightweight design, the ecoTEC Plus 435 can potentially be installed within a kitchen cupboard.
