Condensing gas boiler VAILLANT ECOTEC PLUS VU 35 CS/1-5 35 kW

Modern condensing boilers use the latent heat contained in water vapor, which significantly increases fuel efficiency and reduces environmental impact. This ensures economical gas consumption and high environmental performance.

Description and key features

High-efficiency gas wall-mounted condensing boiler.

The innovative IoniDetect system automatically adapts the boiler operation to the quality of the supplied gas, optimizing the gas-air ratio.

Wide modulation range from 12% for precise power adjustment.

LIN bus technology provides access to extended data, improving diagnostics and system settings.

Heating circuit resistance control system eliminates the need for a bypass, reduces hydraulic noise, and optimizes the operation of the circulation pump.

Automatic refilling and pressure control simplify operation.

Intuitive setup assistant and text display help quickly prepare the boiler for operation.

Low noise level ensures comfortable operation in residential areas.

Remote control and diagnostics via the internet when the appropriate module is connected.
