Overview

Extremely reliable and displaying all the in-built quality you’ve come to expect from Vaillant, the ecoTEC plus is clearly one of the best open vent solutions available today – Where homes utilize a traditional open-vented system to provide their heating and hot water, the ecoTEC plus open vent boiler is the ideal way to deliver exceptional energy efficient performance.

Available in six different outputs 12, 15, 18, 24, 30 and 35kW – ecoTEC plus open vent boilers are the most compact boilers ever developed by Vaillant. This kitchen-friendly design, along with excellent siting versatility and low lift weight ensure a quick and straightforward installation.

At Vaillant we are working towards low carbon solutions today. As part of the HyDeploy project, Vaillant boilers have been tested with up to 20% hydrogen blended with Natural Gas, and we are currently undergoing many tests to each of our boilers to validate their compatibility with up to 20% hydrogen.

*5 years out of the box guarantee. 10 year free extended Advance guarantee available when fitted with a boiler protection kit, excludes 48 and 64kW light commercial boilers
