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.
