Overview

The ecoTEC plus high efficiency boiler range, from Vaillant, uses premium components for outstanding performance, quality, reliability and efficiency - the very best in home heating. Innovative new electronic gas and air modulation system, provides the accurate electronic modulation of gas and air for clean, low emission combustion. Wide modulation range of 1:6 (16%) provides a low minimum output for use in properties with small heat loads or where multiple heating zones have been used. The Vaillant ecoTEC plus assures comfort, even in the unlikely event of a combustion fault, the boiler will revert to the last known operating condition to provide a degree of heat and hot water until the fault is fixed. Lightweight and compact, the ecoTEC plus can be easily wall mounted, or installed in areas which have limited space. The boiler also has a clean look, visually fitting into any environment, while providing easy to use controls to ensure greater efficiency.

This kit provides the facility to apply outside air temperature control to the boiler water flow temperature which provides energy savings. The outside sensor provided measures outside air temperature and sends a signal to the boiler, which adjusts the maximum boiler flow temperature in response. If outside air temperature is greater than the system design temperature, the boiler flow temperature is reduced providing running cost savings. The boiler will operate in the condensing mode more frequently increasing savings. Once the sensor is fitted it is automatically detected. The sensor operation may be configured by adjustment of the boiler operating parameters, if necessary.

Suitable for use with Ideal's Logic+ and Vogue range of boilers, this Flue Vertical Connector helps allow for the connection of a vertical flue pipe directly from a boiler. Easy to install, simply slot both the connector onto your boiler, and then the vertical flue pipes with the easy to use connections. The vertical connector helps funnel the flue fumes out from the boiler, stopping any acidic condensate from staying in the system and therefore causing issues within the system. The robust plastic design will provide a long lasting connection that will last just as long as the boiler.

The Vaillant ecoTEC plus range of high efficiency boilers combine fantastic efficiency levels and high performance with great usability. Thanks to continuous modulation and real combustion control by a multi-sensor system, they achieve high efficiency at the lowest emissions. Due to the boiler's fantastic efficient performance, hot water heats up in just 5 seconds, meaning no hot water tanks are necessary. Vaillant Combi Boilers are highly efficient and deliver a top SEDBUK Band 'A' rated fuel efficiency and powerful domestic hot water performance. Easy to install, a simple step by step wizard is included to provide a quicker 'first time right' set up, and removable side panels allow for greater access to the internal components, meaning the boiler will produce hot water as quickly as possible.
