ASME DHW Stock Storage Tanks, 235-534 Gallon

Storage tanks are required in conjunction with WH water heaters. The heater provides rapid heating of a small volume of water; the tank provides a storage medium with enough capacity to handle short-term loads.

This separation of functions provides extremely fast, flexible recovery. Under ASME section IV part HLW rules, an ASME-compliant tank is required when the total system volume exceeds 120 gallons, or when the total heating capacity exceeds 200,000 BTUH. When properly selected and installed, these tanks can provide 80% draw without appreciable temperature decrease in a single-temperature application.
