Quadrate water heater created by Vogel flug is a water storage device with an electric heating of water with special high temperature glass -titanium enamel coating, which is 350 micron thick, applied in a liquid way, with roasting at a temperature of 850 degrees.
Inner tank of the electric water heaters Vogel flug is made of special low-alloy steel produced in Austria, with a thickness of 2.2 mm.

The patented flanger technology INOX Dry иhas a thickness of 4mm stainless steel and is attached to the internal tank of the boiler by 4 bolts through the elastic gasket, the patented technology of the INOX Dry water heater has an ellipsoid shape and is attached to the internal tank of the boiler on one bolt through an elastic gasket, this fix completely eliminate leakage at the junction.

To provide heat insulation, the inner tank is insulted with a layer of thermal insulation from a homogeneous chlorofluorocarbon - free polyurethane foam 40-80 mm thick ( at the sides and corners respectively), and complies with the new EU standards from 01.01.2016 on energy savings. This insulation thickness ensures minimum heat loss of the water heated in the boiler.

The remote thermostat functions as a smooth regulation of the water temperature, and the thermal limiter protects the water heater from overheating.

The innovative technology of the INOX Dry flange consists in the tubes for the thermostat and heating elements made of stainless steel. There is no additional enamel coating in it, which has a positive effect on heat transfer. This makes it possible to increase the efficiency of the dry heater, and to approximate its efficiency to the wet element (since the wet heating element is in contact with water, its efficiency is higher than that of a dry heating element) and guarantees the highest performance properties.

Also in the manufacturer of a dry Vogel flug heating element, there are technological gaps in the heating coil at the bending points, which allows to get rid of the problems of overheating at the point of inflexion.

Build-in magnesium anode (minimum lifetime of an anode is 2 years).

The operating modes are controlled by an external thermostat with independent additional thermal protection.
Two independent temperature sensors. Remote thermo indicator. Indication of the operating mode.

Working pressure 0.8 MPa (subject -1.6).

Waterproof class IP24.

All the components of the water heater are produced in the European Union. This is confirmed by the certificate euro 1 and certificates of correspondence.
