Aestiva Solar Hot Water Controllers & Sensors
Aestiva controllers are fitted to Apricus and Thermann solar hot water systems, and to some later-model systems sold under other names. We stock the controllers, both sensor types, and complete pump stations.
✔ Controllers
- Aestiva 2 Sensor — roof + tank
- Aestiva 3 Sensor — roof + tank + third sensor
- Apricus-badged and Thermann-badged versions of both
All controllers include free thermal heat paste.
✔ Sensors — check your plug style first
Aestiva roof sensors come in old style and new style plugs, and they are not interchangeable. Before ordering, unplug the existing sensor and photograph the connector.
- Aestiva Roof Sensor 20m (old style plug)
- Aestiva Roof Sensor 20m (new style plug), including Apricus and Thermann versions
- Aestiva Tank Sensor
✔ Pump stations
Complete pump stations with Aestiva 1-2 or 1-3 controller and full enclosure — the simplest fix when the pump, controller and valves have all reached end of life together.
✔ Why buy from us
