3. Description
3.1 Heater construction
The heater is made of a steel vessel (100 l volume at VIADRUS OV 100 L heater) in which there is installed
the spiral heating wire. The vessel internal surface is enamelled and together with the anode rod it creates an
efficient protection against corrosion and guarantees a long-time service life.
The spiral heating wire is made of a metal pipe and is treated by an enamelled layer. The heater is equipped
with a cover; after unscrewing the cover the vessel can be checked and cleaned.
At VIADRUS OV 100 L heater the cover is screwed to the upper neck of the vessel. In the cover there are
installed the reservoirs for thermostat and thermometer probes and there is screwed the anode protective rod
plus the hot service water input and output. Heating water input and output are at the back of the heater.
The heat loss is reduced markedly by the foam polyurethane insulation.

through a T-joint connected to the discharge hole.
