The new design of ecoTEC pure immediately recalls the quality and reliability that characterizes Vaillant's DNA. Indoor condensing boiler with standard Vaillant measurements 72 cm high, 44 cm wide and 33 cm deep.

 

EcoTEC pure is the ideal solution for anyone who wants to switch to Vaillant with no worries because it is equipped with vertical connections that make it quick and easy to install.Vaillant quality guarantees low consumption and good energy efficiency: the boiler is class A in both heating and DHW.

 

The pure range consists of a single natural gas model with combined production. A kit allows switching to propane and propane air supply. The boiler features a new thermohydraulic module equipped with a modulating pump to ensure low electricity consumption while a new stainless steel exchanger and a wide modulation range of up to 1:4 ensure gas savings.

 

EcoTEC pure is the range dedicated to replacements of boilers of other brands, possible thanks to the simplicity of vertical connections and ease of use.


 

Ease of operation thanks to a highly simplified set of controls and display, suitable for all types of customers. Vaillant has found an innovative solution to prevent freezing of the condensate siphon, the element most sensitive to frost, and thanks to the ecoLEVEL accessory it is possible to channel the condensate into the appropriate drains.

 

The boiler mounts a new high-efficiency pump with high performance, a stainless steel exchanger and an 8-liter expansion tank.
