Combined heat storage tank SG(K) KUMULO 380/120l with 1 coil in the external tank, rigid polyurethane foam, skay 71-404000

Combined heat storage tank – an effective solution for your heating system

The SG(K) KUMULO 380/120l combined heat storage tank is a versatile device that allows you to integrate various heat sources into one system. It is ideally suited for installations with a solid fuel boiler, heat pump, fireplace, and solar collectors. The tank design allows for the storage and utilization of excess energy, which translates into savings and user comfort. This is a solution for demanding users who value independence and energy efficiency.

Construction and application

This model combines the functions of a heat buffer and a domestic hot water (DHW) tank. The tank consists of two parts: a larger, unenameled outer tank with a capacity of 380 liters, which is used to accumulate heat from various sources, and a smaller, internal DHW tank with a capacity of 120 liters covered with high-quality EXTRA GLASS® ceramic enamel. A spiral coil located in the outer tank ensures efficient heat exchange with the heating medium. The whole is insulated with rigid polyurethane foam, which minimizes heat loss and ensures long-term temperature maintenance.

• Versatility: Possibility of connecting various heat sources – central heating boiler, heat pump, fireplace, solar collectors.
• Two in one: Heat buffer and DHW tank function, optimizing energy use.
• High-quality materials: Tank made of steel, and the internal tank coated with EXTRA GLASS® ceramic enamel providing corrosion resistance and durability.
• Effective insulation: Rigid polyurethane foam minimizes heat loss and reduces operating costs.
• Spiral coil: Provides a large heat exchange surface and fast water heating.

Operating parameters and installation

The SG(K) KUMULO 380/120l tank is designed for easy installation and intuitive operation. Energy efficiency class B guarantees reasonable energy consumption. Additionally, the possibility of installing an GE electric kit allows for water heating in the absence of access to another heat source or as additional support during periods of increased DHW demand. The use of a magnesium anode protects against corrosion and extends the life of the device – this is particularly important when working with different types of tap water.

Made of steel, it has an internal DHW tank, which is protected with EXTRA GLASS® ceramic enamel and insulated with rigid polyurethane foam, and the outer tank contains a spiral coil - the whole is characterized by energy efficiency class B. Remember that proper installation should be carried out by a qualified installer in accordance with the manufacturer's instructions and applicable standards and building regulations!
