Hygienic Water Heater

Qube X

Multi – Sources heat accumulator

Our exceptional technical design supports connection of up to:

  • 2 electric heating elements
  • solar thermal in a drain back connection
  • 2 free heat exchangers that may be used for:
    • 2 additional heat sources like heat pump, any type of boiler, pressurized solar or
    • 1 heat source + 1 heat consumer like underfloor heating circuit


  • Renovations of hot water systems
  • Large hot water outputs
  • Clean hot water in clean spaces
  • Where the budget is limited
  • Energy efficient installations
  • Harshest environment


  • Lightweight
  • Easy to manipulate
  • Installer friendly
  • Lower transport costs

Hygienic on-demand domestic hot water

  • 10÷30% energy savings due to on-demand principle of heating of water for domestic use. It uses energy to heat up the
    water only when the user opens the tap
  • Improved Legionella prevention through the use of continuous flow principle
  • Application - in the HORECA industry, kindergartens, schools, hospitals, and residential areas

Water medium for heat transfer instead of glycol

  • Water has superior heat transfer properties compared to propylene or ethylene glycol because of a high thermal capacity and
    low viscosity.
  • Unlimited Application - anywhere, including installations where contamination potential is not allowed
  • Highest Solar Thermal Efficiency - Water has higher thermal conductivity compared to glycol
  • Minimum Maintenance - No need for concentration check up and potential glycol based corrosion
  • Low Cost - Glycol solutions are more expensive than water, plus necessary equipment for its handling and maintenance
