SPIDERfire® is a family of ultra high efficiency commercial gas water heaters with up to a 97 percent thermal efficiency.

Features & Benefits

The advanced line of 80 and 100-gallon Rheem-Ruud 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.

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. The display is located at eye level and includes a scrollable, operational history to detail usage patterns and assist with troubleshooting.

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.

Easier, Less Costly Venting

Because more heat is delivered to the water, the cooler flue gases permit venting through standard PVC, CPVC and ABS pipe. SPIDERfire can be installed virtually anywhere.

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 provide installation flexibility.

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-to-Pilot Ignition System

Energy saving ignition that ignites pilot only when there is a call for heat.

Altitude Certification

Certified up to 8,999 feet

CSA/ASME Rated T&P Valve

Factory installed relief valve
