Vaillant ecoTEC plus combines high quality, minimal consumption, and optimal heating comfort. With the ecoTEC plus, you can heat smartly without compromising on proven quality. The ecoTEC plus is a closed boiler with an extra-safe metal casing, acoustic insulation, and a safety siphon that prevents the leakage of combustion gases. The boiler ensures reliable operation, meaning that it will continue to provide heat, even if one of the components temporarily fails.
Future-Proof
In the future, it might be possible to heat with natural gas that is mixed with up to 20% hydrogen. Hydrogen is a promising energy source that could eventually enable the transition to a CO2-neutral energy supply. Our ecoTEC plus is already suitable for the mixing of 20% hydrogen with natural gas. The boiler has been extensively tested and validated to safely heat homes and provide hot water with 20% hydrogen without any adjustments.
In addition, the ecoTEC plus is hybrid-ready; the heating system can be expanded with a heat pump. This allows you to use renewable energy sources and heat more efficiently than ever before. Control or remote control is possible with the optional sensoNET gateway in combination with the sensoAPP.
