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.

Hanson Tanks offers a full range of standard and custom water storage tanks, and has several of the most popular sizes in stock for immediate shipment.

Thermal expansion and contraction of the water in a heating system is contained in a small tank installed at the highest point in the system. Hanson expansion tanks include all the necessary FNPT openings to install valves, gauges and controls, and are available galvanized or plain. Industry standard sizes are from 15 to 400 U.S. gallons.

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.
