EcoTEC Pro VMW boiler
All models in the VMW ecoTEC pro range have an efficiency etas = 94%. For this reason, if combined with class VI thermoregulation (such as vSmart), they reach a system efficiency of 98% and therefore the ErP system energy class in heating A+ .
The ecoTEC pro VMW boiler (heating and DHW production) is available in 23kW and 28 kW powers.
ecoTEC pro was born as the natural evolution of Vaillant's consolidated technology and experience in condensation technology. ecoTEC pro was designed to offer the right balance between performance and comfort both in heating and in the production of domestic hot water. With the new high efficiency pump and new electronics they allow ecoTEC pro to consume very little electricity, guaranteeing significant savings over the year.
Its simplicity of adjustment makes it the ideal boiler for all users, as well as being supplied with an extremely simple interface with clear text and a backlit display to facilitate use.

The ecoTEC pro range includes: the combined version, the smart connectivity version in combination with vSMART, a version designed for installation in multiple collective flues and two versions for installations in single collective flues. ecoTEC pro CM is also the right choice for replacing boilers in multi-family complexes or for more complicated installations. In fact, Vaillant offers a range of products suitable for the flue system as well as multiple options regarding the accessories dedicated to the boiler: a fume pressure switch, combined with the electronics, self-regulates the value to be set for the length of the vertical ducting so as to evacuate the exhausted fumes correctly. The ecoTEC pro CS models are equipped with a dedicated kit, included in the supply, consisting of a smoke non-return valve, 87° bend and 80/125mm rigid section for connection to a single collective flue
