Features and Benefits

Features and Benefits

 N/A The advanced line of 80 and 100-gallon Rheem® SPIDERfire® condensing water heaters offers breakthrough technology. It provides up to 97% thermal efficiency. The patented heat transfer system dramatically cuts fuel costs and is built to last. Models are available that range from 130,000-399,900 Btu/h, with a maximum temperature setting of 185 degrees.

Faster, Less Costly Venting
All models vent with standard -2", -3", -4", or -6" diameter PVC plastic pipe. SPIDERfire®'s built-in exhaust riser vents at the top and eliminates the need to construct a side riser.

Smart LCD Control System
The new diagnostic system is standard on all SPIDERfire® models. It enables installers and service technicians to monitor key functions and components. It includes a scrollable, operational history.

Innovative Technology
The heart of the SPIDERfire® is its patented multi-leg, triple pass heat exchanger. The system is engineered as a 'wet base' design wherein the entire heat exchanger is submerged. That eliminates hot spots found in some other fully condensing water heaters. When hot spots are eliminated, the life of the product is extended and efficiency is maximized. These products are built to last.

Power or Power Direct Vent
It can be installed as a power-vented product; or as a power direct-vented product - the latter for negative air pressure or if indoor air quality is a concern.

Corrosion Protection
Three-pass heat exchanger tubes are coated inside and out with a specially formulated porcelain enamel designed to protect against condensation.

Multiple Water Connections
Hot and cold water Inlets and outlets on both sides of the unit; 2" NPT high-flow connections.

Full-port, Full-flow Drain Valve
Factory installed brass drain valve allows for faster draining and servicing.

Advanced Burner Design
Latest models have increased burner surface area for ultra smooth ignition and quiet operation.

Direct Spark Ignition System
Energy saving ignition that ignites pilot only when there is a call for heat.

General Information

General Information

 N/A Efficiency
All models tested according to ANSI test procedures, and meet or exceed the thermal efficiency and standby loss requirements of ASHRAE standard (EPact). Also exceeds energy efficiency codes of all states including California Energy Commission (CEC).

Safety and Construction
Design certified by CSA: For operation at 185 degrees; meets all safety and construction requirement of ANSI Z-21.10.3; as an automatic storage or instantaneous water heater; as an automatic circulating tank water heater; and for operation on combustible floors and in alcove installations. Certified for 150 PSI maximum working pressure (160 PSI for ASME models).

Optional Construction
ASME construction is available on designated models. UL Sanitation (NSF5) compliant models are available when equipped with optional seal kit (Part No. AS42690).
