The new generation of ecoTEC appliances is more efficient, more durable and easier to use than ever before. They are so compact that they fit in the smallest niche, and yet are so effective that they provide single and multi-family houses at any time reliably with central heating and hot water.

The multi-talented ecoTEC plus is concentrated heating power on only 0,32m² of wall area. With up to 35kW of power, it supplies even larger houses more efficiently and reliably than ever before. The new model uses an electronic gas-air mix system and operates with optimum modulation. This reduces energy consumption and emissions, and also increases the efficiency of water heating. The integral condensation heat exchanger and the new high efficiency pumps provide additional energy savings. And the ingenious connection system allows the quick and perfect installation in any location.
