Benefits

INSULATION
Storage tanks models 1000 and 1100 use high density fiberglass. Model CS120 have a two (2) inch thick uniform blanket of GREENFOAM® ecofriendly insulation.

INNER TANK
A uniquely formulated blue cobalt glass enriched with zircon is fused to specially treated steel at 1,600°F (871°C) to provide the best coating available against corrosion for many years. The tank is certified at a test pressure of 300 PSI (2,068 kPa) and a working pressure of 150 PSI (1,034 kPa).

ANODE
A unique magnesium anode (AZ31) in excess of CSA standard C309 requirements is provided for rust prevention.

FACTORY INSTALLED 3/4" NPT DI-ELECTRIC NIPPLE
Extend the life of the water heater by providing excellent corrosion protection.

COLD WATER SUPPLY
Commercial ISO models do not come with square flange adapters, are not equipped with a brass combination drain valve, and have different hot and cold water piping connections than the other models.

TEMPERATURE & PRESSURE-RELIEF VALVE
For safety purposes, a temperature & pressure-relief valve MUST be included in the installation of all Giant STORAGE tanks. This valve will protect the tank from the damaging effects of excessive temperature and pressure.

All models are suitable for potable water and space heating applications. Toxic chemicals, such as those used for boiler treatment, must NEVER be introduced into this system. This unit must NEVER be connected to any existing heating system or component(s) previously used with a non-potable water heating appliance.
