Function

Your Vaillant ecoTEC pro is a gas-fired wall-hung high-effi-
ciency boiler, which generates heat for heating and/or
domestic hot water generation.
3.2.1

Heating mode

In heating mode, the boiler heats the hot water and sends it
through the radiators or underfloor heating of your home
(heating circuit). The hot water pumped into the heating cir-
cuit exits the boiler at a specific heating flow temperature,
emits its heat into the rooms and flows back into the boiler
once cooled to return temperature. The heating water is
then heated again.

3.2.2 Domestic hot water generation

When you open a hot water valve (sink, shower, bath, etc.),
the boiler operates automatically and supplies hot water at
a temperature set by you.
When you close the hot water tap. the boiler automatically
stops producing hot water.
If you have activated Comfort mode, the boiler supplies you
with hot water at the requested temperature without you
having to wait for the water to heat up.

To prevent unnecessary energy loss, do not set
the temperature higher than is required.
