The tanks are manufactured in accordance with the European standards and are available in capacities from 150L to 1000L.
They have up to two spiral heat exchangers which heat up the water in the main tank.
Depending on the configuration the heat exchanger can be connected to the solar collectors, a burner (oil, pellet, wood, gas, etc.), heat pump, buffer tanks and, in general, devices for closed water heating circuit.
The tank also disposes sockets for temperature sensors, thermometers and electrical resistance.
