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.
