The combined tank is an innovative solution in heating systems, integrating the functions of domestic hot water (DHW) storage and a heat buffer in a single unit.
This all‑in‑one tank stores hot water for daily sanitary use while simultaneously acting as a thermal buffer, optimising the operation of the entire heating system.

Advantages of two water tanks in one

• Dual functionality: The combined tank provides both the storage of domestic hot water – ready for immediate use on demand – and the function of a heat buffer, which balances the operation of the heat source (e.g., boiler, solar collectors) by storing excess thermal energy.
• Space saving: Integrating two functions in one tank eliminates the need for two separate units, translating into significant space savings in the technical room.
• High‑grade stainless steel: SUS316L stainless steel is used as the internal material of the domestic hot water tank, offering superior overall corrosion resistance.
• Durable construction: The tank incorporates advanced welding technology, which effectively enhances quality, durability, tensile strength, and extends the tank’s service life.
