🔥 What it is

The Rheem ST80 is an 80-gallon insulated hot water storage tank used in commercial and large residential hot water systems.


⚙️ What it does

It does not heat water on its own. Instead, it:

  • Stores large volumes of already-heated water
  • Works with a boiler or water heater system
  • Helps supply high-demand hot water quickly
  • Smooths out demand spikes (showers, laundry, commercial use)

🧰 Key features

  • Capacity: 80 gallons
  • Construction: glass-lined / porcelain enamel steel tank
  • Insulation: rigid polyurethane foam
  • Pressure rating: typically 150 PSI
  • Connections: large 2-inch inlet/outlet fittings
  • ASME-rated versions available depending on model
  • Designed for commercial hot water systems

🏢 Where it’s used

  • Apartment buildings
  • Schools / gyms / commercial facilities
  • Large homes with high hot water demand
  • Boiler-based hydronic hot water systems

🧠 Simple explanation

It’s basically a big insulated “hot water holding tank” that sits between a heater/boiler and your fixtures so you don’t run out of hot water during heavy use.
