Twin-layer tank designed to work with a dual-function gas boiler. The division of hot water into layers makes that water intake does not start up gas boiler every time, which has an impact on boiler life and gas saving. Tank has a capacity of 100 litres of hot water. Insulation is made of polyurethane foam which reduces heat loss to a minimum. Inner coating of tank is made of wet-foamed and fired at 850 °C ceramic enamel. Such technology guarantees filling all gaps and corrosion protection. An additional protection against corrosion is a magnesium anode, condition checking and regular replacement of anode ensures a long life. The outer casing is metal, which protects tank from accidental damage to thermal insulation. Cold water is fed to the lower part of tank by a three-stage circulation pump with adjustable capacity.

All tank connections are located in the upper bottom of tank, which facilitates installation and operation. There is also a management thermostat and a switch on top of tank. The low height allows installation underneath every gas stove already installed. Horizontal adjustment is possible with adjustable feet on bottom of tank.
