Boiler Vaillant ecoTEC PURE VMW ES 236/7-2

The new Vaillant ecoTEC PURE VMW ES 236/7-2 is a mixed condensing wall boiler with a power of 23 kW for hot water and 19 kW for heating with energy efficiency class A for heating and DHW, and XL load profile. It complies with the new European ErP regulation.

Simply, great
Vaillant expands its range of condensing boilers with the new ecoTEC pure mixed wall boilers, boilers that have the robustness, high quality and exclusive design that characterize the other models of the brand. Available in powers of 23 and 28 kW, the new ecoTEC pure respond to the need to meet the needs of those users who demand a basic condensing boiler but with the guarantee of a brand such as Vaillant.

Comfort and savings for the user
The ecoTEC pure boilers guarantee a high efficiency, which can even be increased with Vaillant modulating regulators, allowing maximum savings in gas consumption. In addition, they are prepared to work as support in the production of ACS with solar energy.

New design
Conserving the same dimensions (720x440x335mm) for the two powers and the same position between connections as the other ranges, the design has been renewed maintaining the identity sign of the elegant Vaillant design. They have a new central display lit in blue and with an intuitive and easy to use control panel that has been developed in collaboration with users and installers.

Low consumption in Stand-By
When the boiler is not heating, it is in stand-by, consuming energy during all this time. Vaillant reduces this consumption to a minimum by reducing 4W per year compared to the previous ranges, which means a consumption of less than 2W per year.

Proven superior quality

• Stainless steel primary heat exchanger
• New condensate collection siphon
• New hydraulic block
• High efficiency pump

Simple installation
The smoke outlet accessories are the same as in the rest of the ranges. And although the installation template is different from the rest of Vaillant ecoTEC boilers, the new position of the sockets allows a quick and easy installation in cases of replacement.

Wide range of installation accessories
Available to facilitate installation both hydraulics and gas outlet. Maximum quality guaranteed Designed in Germany, the same process and quality tests have been followed in its production as in the rest of Vaillant condensing boilers.

High efficiency circulation pump
Vaillant incorporates highly efficient modulating pumps in its boilers, reducing considerably the electrical consumption during operation and also while it is not working.

Regulation and Control
The eBUS technology makes Vaillant thermostats and chronothermostats fully compatible to integrate into any type of system, from very simple ones that only need a thermostat to more complex systems such as solar, hybrid systems with heat pumps, ventilation, etc. Vaillant systems fully updatable, modifiable, expandable in a simple way with management and control made from the same control unit for everything.

With the new vSmart WiFi Thermostat you can control your boiler and heating with your smartphone (iPhone / Android) or tablet from anywhere, so you can adjust the temperature of the heating for when you get home or stop it in case you left it on going. Therefore, if you want this thermostat you have to choose it when you select the type of fuel from the boiler or if you want us to install it, before adding the boiler to the cart.
