Vaillant ecoTEC pure condensing combi boiler

ecoTEC pure is a straightforward condensing combi with A energy efficiency in both heating and hot water. It suits standard flats moving to condensing technology without stretching the budget.

Capacity: 20–35 kW
Energy class: A

The XL hot water load profile marks the class that comfortably covers the daily demand of a one-bathroom flat. Aqua Sensor technology keeps the water temperature steady even at low flow rates.

Its compact case can be fitted inside a kitchen cupboard, which frees up space in narrow kitchens. During the survey we check the flue route and the cupboard dimensions together and produce a clear layout before installation.
