The new ecoTEC intro VMW condensing boilers (for heating and domestic hot water production) are available in 24 and 28 kW ratings, increasing the range of product choices within Vaillant's established range of condensing boilers. In fact, this product gives new users the opportunity to approach the world of condensing boilers offered by Vaillant as well, without going to the excessive cost of replacing the old boiler. ecoTEC intro maintains the focus on energy savings by mounting a high-efficiency modulating pump that minimizes annual electricity consumption, resulting in a positive impact on the bill.

Also in terms of gas saving Vaillant offers the new combustion technology, called fan push, where it is the fan that thanks to different levels of pressure exerted on the gas valve ensures the right ratio between combustion air and gas. The case of ecoTEC intro is simple and essential, the dimensions turn out to be extremely small which, however, does not affect or reduce the quality and efficiency of the product, guaranteed by Vaillant.

 

The front panel introduces an innovative touch screen interface of extreme simplicity with 6 buttons, black background display, and 2 digits in white with intermittent lighting. An additional e-bus connector has been added to the bottom of the boiler to allow connection to Vaillant temperature control units and thermostats.

 

These wall-mounted boilers are very easy to install thanks to its size (62.6cm height, 40cm width and 27cm depth) and low weight (about 26kg): these features make it ideal whenever replacement is needed.

 

ecoTEC intro is approved for outdoor installation down to -5°C and for installation inside built-in units (art. 0010030848) down to -5°C.

 

All components inside the product comply with ErP energy efficiency regulations, a guideline also espoused by Vaillant as an environmentally sensitive brand. This is all that the new ecoTEC intro can offer, plus a competitive price that does not affect performance.
