Description of water tank
Hygienic Combi tanks are used To produce and accumulate sanitary hot water and hot water for space-
heating system.
Coil-in-Tank construction- Flexible stainless-steel coil for sanitary hot water +Buffer tank powering space-
heating system. Sanitary water heats up instantaneously as it flows through the large surface stainless coil.
Thus water is delivered hot while still fresh and clean of depositions.
HYG series
-Inlet/Outlet arrangement –180 angle degrees.
HYG-B series
-Inlet/Outlet arrangement –90 angle degrees.
HYG /HYG -B
models, the heat source is an electric heater.
HYG R/ HYG-BR
models have a built-in heat exchanger (coil type) designed to connect to a solar installation or
boiler. Option for installation of an electric heating element.
HYG R2 / HYG-BR2
models have two built-in heat exchanger (coil type) for connection to the solar system and
boiler. Option for installation of an electric heating element.
3.1.
Removable insulation and outer casing
The quality of the insulation of a water heater is a key factor for its heat conservation capability and energy
efficiency.
All
Hygienic Combi tanks HYG series/HYG-B series
have Removable insulation with thickness 100 mm (DIN
4753, part 8) and outer casing of PVC with RAL 9006 color.
3.2.
Water tank
Floor standing. Water tank is made of low-carbon steel S235JR,
DHW tube of sanitary grade stainless steel -316L, heats up instantaneously.
All threads are internal (see technical parameters).

In the table of technical parameters is specified location for installation of electric heating element
The connection of the electric heating element to the electric power supply must be
done by a qualified electricians.
When connect the heating element to the electric network, make sure that it is properly
grounded.
