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.
