The Vaillant ecoTEC plus combines high quality, minimal consumption, and optimal heating comfort. With the ecoTEC plus, you can heat efficiently without compromising on proven quality. The ecoTEC plus is a sealed boiler with an additional safe metal casing with acoustic insulation and a safety siphon that prevents the leakage of combustion gases. The boiler ensures reliable operation. This means that the unit will always deliver heat, even if one of its components temporarily fails.
Future-Proof
In the future, it may be possible to heat with natural gas mixed with up to 20% hydrogen. Hydrogen is a promising energy source that could ultimately enable the transition to a CO2-neutral energy supply. Our ecoTEC plus is already suitable for mixing 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.
Additionally, 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. Management or remote control is possible with the optional sensoNET gateway in combination with the sensoAPP.
