ecoTEC wall-hung condensing boiler range

Lightweight for its class and with a compact design, the ecoTEC wall-hung boiler can be sited almost anywhere.

This versatile condensing boiler includes a comprehensive range of flues, fittings and accessories and is available in five output ranges (46, 6580, 100 and 120 kW).

For larger buildings, or those with more complex layouts, multiple boilers can be installed in cascade to provide a highly efficient heating system. Whether installed on a wall or using our modular cascade rigging system, they automatically optimise heat and hot water supply according to the system’s individual needs.

Each unit features a highly advanced diagnostic display that’s surprisingly easy to use. A single electronic circuit board makes commissioning, servicing and operation less taxing, and best in class emissions within European standards are achieved with a fully modulating low NOx burner that automatically matches heat output to demand.

Fully compatible with Vaillant’s range of intelligent eBUS controls and with flue lengths up to 24m concentric, the ecoTEC range is designed to excel in a variety of commercial applications.
