HOT WATER STORAGE TANKS
Hotels. apartment buildings, hospitals and other facilities that need constant
supplies of hot water usually have a storage tank that has been sized to
meet peak demands, even though the usage at these times exceeds the output
of the heater. This is achieved by selecting a tank of sufficient size,
with adequate insulation, and designed to prevent incoming cold water from
mixing with the hot water supply. These tanks are normally lined to prevent
rusting, and the standard design working pressure is 125 psi, which exceeds
typical city water mains pressure.

Thermal expansion and contraction of the water in a heating system is contained

and controls, and are available galvanized or plain. Industry standard

Periodic boiler maintenance includes a blowdown cycle to reduce scaling.
Local laws usually do not allow high temperature water to be dumped into
sewers, and a blowdown tank system is designed to reduce temperatures by
mixing cold water with the effluent. It also enables high pressure water
to flash to steam safely. Hanson Tank manufactures a range of recommended
sizes based on boiler capacity.
