CTA

CTA is an independent, family-owned Swiss company headquartered in Münsingen in the canton of Bern. Since 1981 the company has focused on renewable energy and energy-efficient systems. The units are developed, manufactured, assembled and tested in Münsingen. The business is now run by the second generation, Marco Andreoli, following founder Gregor Andreoli.

The heat pump range splits into two lines. The Optiheat ground source heat pumps draw on boreholes or groundwater and are installed indoors. The Aeroheat air-to-water units come in indoor and outdoor versions and draw on outside air. All-in-one variants with a built-in tank are also available. Service and maintenance run through the company's own network across Switzerland.
