Vaillant ecoTEC plus combines high quality, minimal consumption, and optimal heat comfort. With the ecoTEC plus, you can heat intelligently without compromising on proven quality. The ecoTEC plus is a sealed unit with an extra-safe metal casing with acoustic insulation and a safety siphon that prevents the leakage of combustion gases. The unit ensures reliable operation, meaning it will continue to provide heat, even if one of the components temporarily fails.
Future-Proof
It may be possible in the future to heat with natural gas that contains up to 20% hydrogen. Hydrogen is a promising energy source that could eventually make the transition to a CO2-neutral energy supply possible. Our ecoTEC plus is already suitable for the blending of 20% hydrogen into natural gas. The boiler has been thoroughly tested and validated to safely heat homes and provide hot water with 20% hydrogen, without the need for any modifications.
In addition, the ecoTEC plus is hybrid-ready; the heating system can be expanded with a heat pump. This allows you to take advantage of 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.
