EcoTEC pro is the ideal boiler for Vaillant on Vaillant replacements: installation is quick and easy as is the adjustment of operating parameters.

 

The ecoTEC pro range includes: the combined version, the smart connectivity version in combination with sensoROOM connect, a version designed for installation in multiple flues, and two versions for installations in single flues.

 

EcoTEC pro CM is also the right choice for boiler replacement in multifamily complexes or for more complicated installations. In fact, Vaillant provides a range of products suitable for flue as well as multiple options in terms of dedicated boiler accessories: a flue pressure switch, combined with electronics, self-adjusts the value to be set for the length of the vertical ducting so as to properly evacuate exhaust fumes.

 

ecoTEC pro CS models are equipped with a dedicated kit, included in the supply, consisting of a flue gas check valve, 87° bend and 80/125mm rigid section to connect to a single collective flue.

 

All models in the ecoTEC pro VMW range have an efficiency etas = 94%. Therefore, when combined with class VI thermoregulation (such as vSmart), they achieve a system efficiency of 98% and thus the ErP system energy class in heating A+.

 

EcoTEC pro was born as the natural evolution of Vaillant's established technology and experience in condensing technology. ecoTEC pro is designed to offer the right balance of performance and comfort in both heating and domestic hot water production. With its new high-efficiency pump and new electronics, it enables ecoTEC pro to consume very little electricity, providing significant savings over the year.

 

Its simplicity of regulation makes it the ideal boiler for all users, as well as featuring an extremely simple interface with plain text and backlit display for easy operation.
