Vaillant ecoTEC intro condensing combi boiler

ecoTEC intro is Vaillant’s entry-level full condensing combi, sold in 24 kW and 28 kW outputs. It suits the typical two and three bedroom flats of Antalya as well as rental properties.

Capacity: 24 / 28 kW
Energy class: A

Despite being an entry model it condenses fully, recovering heat from the flue gases and using noticeably less gas than a conventional boiler. A hot water flow of 13.4 L/min covers the demand of a one-bathroom flat.

Its 1:7 modulation ratio keeps the appliance efficient through the mild Antalya winter, when heat demand is low. It is one of the models we recommend most often for tight-budget refurbishments.
