Appliance characteristics
The Vaillant ecoTEC plus 937 is a compact gas wall-
mounted boiler with condensing technology and 15 litre
laminar stainless steel storage tank.
The Vaillant ecoTEC plus 937 provides central heating
and hot water, whereby the hot water is supplied direct
from the boiler. Hot water provision takes place
automatically when the hot water tap is opened. This
involves automatic control of the boiler so that the
demand for heating and hot water is automatically
covered in the most economic way.
Recommended accessories
Vaillant have a range of control accessories that can
either push-fit into the boiler fascia or be wall mounted.
