Combined heat storage tank SG(K) KUMULO 800/200L two spiral heat exchangers, dismantleable soft polyurethane foam 100mm skay 72-808600

Combined heat storage tank – an effective solution for your home

This SG(K) KUMULO combined heat storage tank with a capacity of 800/200 liters is a versatile device that allows you to integrate various heat sources into one system. It is an ideal solution for both installers and end-users looking for an effective way to heat domestic hot water and support central heating. The tank design allows connection of a fireplace, boiler (solid fuel, gas) or heat pump, as well as a solar installation.

Construction and operating principle

The Kumulo tank utilizes the principle of a “tank within a tank”. The internal tank for domestic hot water (200 liters) is surrounded by an external central heating buffer (800 liters). This construction allows for efficient heat exchange between the DHW and CH systems, ensuring optimal energy utilization. Two spiral coils – upper and lower – increase the possibilities of adaptation to different heat sources. The lower coil is dedicated to solar collectors, while the upper one can be supplied, for example, from a gas boiler. Additionally, the tank can be directly powered from a central heating boiler, fireplace or heat pump, providing great flexibility in configuring the heating system.

Advantages and benefits

• Versatility: The ability to cooperate with various heat sources – heat pump, solid fuel boiler, gas boiler, solar collectors – is a key advantage of this tank.

• Space saving: It replaces two separate devices – a DHW heat exchanger and a CH buffer, which allows you to save valuable space in the boiler room.

• High efficiency: Efficient spiral coils ensure fast heating of domestic hot water and effective support for central heating, translating into lower operating costs.

• Comfort of use: Independent power supply of both tanks allows for heat exchange between DHW and CH systems, providing comfortable conditions throughout the year.

• Durability and safety: The internal surface of the tank is covered with EXTRA GLASS® ceramic enamel, which provides high resistance to corrosion and long-term protection against mechanical damage, and a magnesium anode additionally protects against electrolytic corrosion.

• Easy installation and maintenance: Concentration of hydraulic connections in the upper and side bottom of the tank simplifies installation and facilitates access to elements requiring maintenance or replacement.

• Effective insulation: Insulation made of polyurethane foam in a skay/PVC plastic housing minimizes heat loss, reducing heating costs for the building and domestic hot water.

This combined heat storage tank is an investment in comfort, savings and ecological heating solutions for every home!
