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. This powerful condensing boiler is in the CW6 class and delivers 16 liters per minute of hot water (at 60 degrees).
The ecoTEC plus is a sealed unit 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, meaning it continues to deliver heat even if one of the components temporarily fails.
Future-proof
It might become possible in the future to heat with natural gas that has up to 20% hydrogen mixed in. Hydrogen is a promising energy source that could ultimately enable the transition to a CO2-neutral energy supply. Our ecoTEC plus is already compatible with the mixing of up to 20% hydrogen into natural gas. The boiler has been extensively tested and validated to safely and without modification heat homes and provide hot water with 20% hydrogen.
In addition, the ecoTEC plus is hybrid-ready; the heating system can be expanded with a heat pump. This way, you can take advantage of renewable energy sources and heat more efficiently than ever. Management or remote control is possible with the optional sensoNET gateway in combination with the sensoAPP.
