  • Multisources:
    Can simultaneously receive up to three sources of heat :
    Boiler (wood, pellet, heat pump, etc.), … Electrical resistor, …, Solar system.
  • Energy efficient :
    Reinforced rigid foam insulation for minimum losses ! 2 synthetic skins around a reinforced insulation : 30-50% more efficient than a typical hot water storage tank.
  • Perfect sanitation:
    Instantaneous production with no bacterial growth for perfect water !
  • Zero Maintenance :
    Technology with no corrosion or scale deposits.
  • Innovative system
    With the drain-back system setup, the tank water is used as coolant. An environmentally friendly solution, with no overheating or frost worries !
  • Lifetime warranty.
  • Compact form :
    The hot water storage tank is installed in a closet 60 cm deep.
  • Easy Installation:
    The connections are all accessible from the top. With the drain-back system, there is no element to add.
