In large volume domestic hot water tanks the stored water comes from the water supply and can be used for all activities.

The tanks are manufactured in accordance with European standards and are available in capacities from 1500L to 9000L. They have up to three detachable spiral heat exchangers which heat up the water in the main tank.

Depending on the configuration, we can add to the heat exchangers Solar Collectors, a burner (oil, pellet, wood, gas, etc.), heat pump, buffer tanks and, in general, devices with closed water loop heating. The tank also has connectors for temperature sensors, thermometers and electrical resistance.

Areas of application of SUNDWARE Large Volume Tanks: For use in Industries, Hotels and Hospitals; In solar systems for water heating and thermal energy storage, in heat pump systems for storing and heating water, and in biomass systems for storing and heating water.
