Indirect Water Heaters

Available in 30, 38, 45, 75 and 110 Gallon Models

Rheem-Ruud’s indirect coil tank water heaters offer a cost effective water heating alternative.These units use indirect water-to-water heat transfer by circulating boiler-fed hot water through a coil inside the water tank. They’re ideal for applications that use boilers for space heating.

Construction Features:

• Built to last –

tank is manufactured from heavy gauge steel. Longer life equals a higher “return on investment”. Outer jacket is made from steel and powder coated for a lasting, durable finish.

• High temperature porcelain enamel protects all tank and coil –

and maximizes corrosion resistance.

• Factory installed automatic temperature controls –

immersion aquastat on all models.

• Factory installed brass drain valve

• Sediment reduction inlet –

standard on the STID80 and STID120. Reduces sediment buildup on the tank bottom – increasing operating efficiencies and tank life.

• Temperature and pressure relief valve –

CSA/ASME rated and factory installed.

• 1-1/2" Coil diameter – larger diameter, results in higher recovery and less pressure drop through the coil – smooth surface on the coil resists lime build-up.

• 2" Non-CFC foam insulation – provides superior insulating quality and decreases standby heat loss.

• Two heavy-duty magnesium anode rods –

inhibit corrosion and maximize tank life.

• Factory installed dielectric nipples –

provide greater insulating protection against electrolysis.

Tested in accordance with GAMA Indirect-Fired Water Heating Standard IWH-TS-1 – March 2003.

Note: First Hour Rating = First Dray + Continuous Draw Warning: Installation should be in accordance with all national and/or local codes.

In the absence of local codes, refer to NFPA 54 or ANSI Z.21.10.1. Caution: The recommended maximum hot water temperature setting for normal residential use is 120°F. Rheem recommends a tempering

valve or anti-scald valve be installed and used according to the manufacturer’s directions to prevent scalding.
