Layered storage tank MULTI-INOX 800L inox coil for DHW, dismantleable 100mm polyurethane foam, skay 70-801600

Heat accumulation for efficient heating and DHW.

The MULTI-INOX stratified storage tank with a capacity of 800 liters is a solution designed to work with various heat sources – from traditional wood, pellet, gas or oil boilers, to modern heat pumps and heat recovery systems. Its construction allows for efficient accumulation of heat from various sources and its use for both central heating and domestic hot water preparation. This is a versatile device that optimizes the operation of the entire heating system.

Construction and principle of operation

The key element of the tank is the SPIRAFLEX stainless steel coil – a spirally corrugated construction provides a large heat exchange surface and hygienic DHW preparation. The spiral corrugation increases the turbulence of the water flow, which prevents the deposition of scale and the development of legionella bacteria. This coil self-cleans under the influence of pressure changes, minimizing the need for maintenance. The stratified arrangement of the tank allows maintaining different temperatures in different zones – hot water accumulates at the top, and cooler water at the bottom, which increases the efficiency of energy use. Low return water temperature is particularly beneficial for condensing boilers, allowing maximum utilization of the fuel's calorific value.

Advantages for the installer and user

• Versatility: Possibility of connection to various heat sources – solid fuel boilers, gas boilers, oil boilers, heat pumps, solar collectors.

• Hygienic DHW: The SPIRAFLEX stainless steel coil ensures clean and safe domestic hot water thanks to its self-cleaning construction and elimination of the risk of legionella bacteria development.

• Savings: No need to use a magnesium anode eliminates the cost of its replacement and potential problems related to corrosion.

• Efficiency: The stratified arrangement of the tank optimizes energy use and reduces the operating costs of the heating system.

• Installation comfort: Concentration of hydraulic connections on one side facilitates assembly and maintenance of the device. Detachable polyurethane foam insulation (100mm) facilitates transport and installation in confined spaces.

• Durability: Steel construction ensures long device life even in difficult operating conditions.

• Safety: Turbulent water flow in the coil prevents the formation of conditions conducive to the development of Legionella bacteria – there is no need to heat the system as in traditional tanks.

The MULTI-INOX tank is an investment in thermal comfort and energy savings – both for the installer who will appreciate the ease of installation and maintenance, and for the end user who will benefit from lower heating bills and access to clean domestic hot water.
