Description

Modern Thermal Storage Tanks – Durability, Efficiency and Safety

Thermal storage tanks from the W2W series are designed for maximum efficiency, reliability, and user comfort. Thanks to the use of high-quality materials and advanced manufacturing technologies, these units meet the requirements of both domestic installations and more advanced heating systems.

Key Advantages

  • Premium stainless steel – tanks and coils made of certified steel from reputable European manufacturers ensure long service life and corrosion resistance.
  • Structural safety – pickled and passivated welds, along with individual pressure testing of each tank, ensure full tightness and reliability.
  • No anode required – thanks to stainless steel construction, the unit is virtually maintenance-free.
  • High energy efficiency – energy class C reduces energy consumption and operating costs.
  • Durable and aesthetic casing – metal housing with effective insulation minimizes heat loss.
  • Integrated safety components – safety valve included as standard for increased operational safety.
  • PZH certification – compliance with hygiene standards for domestic hot water systems.
  • Quality assurance – clear warranty conditions and long service life confirmed by the manufacturer.

Suitable for Heat Pumps and Auxiliary Heat Sources

  • Dual high-efficiency coils – large heat exchange surface ensures fast water heating and compatibility with multiple heat sources.
  • High heating capacity – large upper coil surface enables rapid system response.
  • Precise temperature control – immersion sleeves allow accurate temperature measurement and control.
  • Vertical design – easy installation and stable operation in various system configurations.
  • Extended equipment – safety valves, temperature and pressure relief valve, and thermometer included as standard.
