Our Combination tanks combine the properties of a Buffer tank and a DHW tank, whereas the water in the main tank is a closed water loop and we can use it for room and water heating.

The water in the immersed tank is the one which will be used for bathing, washing, drinking, etc. The tanks are manufactured in accordance with European standards and are available in capacities from 500L to 2000L. They have up to two 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, burner (oil, pellet, wood, gas, etc.), a heat pump, buffer tanks, and in general devices with closed water loop heating.

Our tank also has connectors for temperature sensors, thermometers and electrical resistance. The immersed tank has a large capacity and can also accept an electrical resistance while it also has anticorrosion protection using liquid enamel which has been heated to 850�C.

Areas of application of SUNDWARE Combination Water Tanks:In solar systems, water heating and hot water storage, in heat pump systems for storing and heating water, and in biomass systems for storing and heating water.
