Hot Water Storage Tank with Coil
WTB 220-400
Chapter 2 |
Construction
Vertical storage tanks with one coil of WTB Series
are pressure equipment, i.e. the pressure within the
storage tanks and coil are equivalent to the pressures
in the corresponding systems.
Storage tank is made of high quality steel and is
equipped with one helical coil that can simultaneous-
ly operate with independent heat source, e.g. a solar
heating system, fi replace with water jacket or central
heating boiler. In each version, the hot water tank is
protected against corrosion by ceramic coating and
insulated protective magnesium anode. Thermal in-
sulation of the tank is a specially selected insulation
that provides excellent thermal insulation properties
of all devices. Storage tanks have aesthetic plastic
housing, a temperature indicator, inspection opening
and connectors for mounting electric heating unit and
connecting the hot water circulation.
