CTA Wärmepumpe mit PV-Anbindung
Münsingen
Tap a star to rate
CTA AG manufactures heat pumps in Münsingen in canton Bern and sells them through a network of Swiss specialist installers. Newer models in the optima and aeroCool lines support the smart grid interface, through which a photovoltaic inverter signals to the heat pump when solar power is available.
In practice, PV coupling noticeably cuts energy costs, since the heat pump preferentially runs when the electricity comes from the homeowner's own system. CTA provides Swiss installers with a partner portal that includes planning documents. The company has been active in the Swiss market for decades and is known for durable units and good spare parts availability.
