The Vaillant ecoTEC plus and ecoTEC pro models are
compact, wall-mounted condensing appliances.
ecoTEC plus and pro combination boilers provides both
central heating and domestic hot water, with the dome-
stic hot water supplied directly from the boiler. The boi-
ler will operate automatically to provide domestic hot
water whenever a hot water tap is opened, and auto-
matically adjusts to meet the demand for both central
heating and domestic hot water in the most economical
way.
ecoTEC system boilers provides central heating and
domestic hot water where a separate indirect hot water
cylinder is also incorporated to the system.
