Combi Tanks

(Tank in tank)

The Combi Tanks comprise two tanks, the external storage tank that provides storage capacity for backup heating purposes and the internal hot water tank that stores domestic hot water. The combination of those two offers space and cost saving, as well as the advantage of using up to three different energy sources.

  • Outer hot water tank of high quality steel (S235 JR)
  • Inner domestic hot water tank: Εnameled according to DIN 4753*
  • External housing of special PVC & highly resistant ABS caps of excellent aesthetics
  • Thermal insulation of 100mm highly efficient Soft PU that minimises heat losses
*The enameling process is carried out in our own industrial facilities and the tanks are checked individually upon exit from the enameling unit, assuring the top quality of the enamel.
