The SPIDERfire ® series puts technological breakthroughs to work to deliver 95% thermal efficiency. Rheem's patented heat transfer system dramatically cuts fuel cost and is built to last. The system is engineered as a 'wet base' design wherein the entire heat exchanger is submerged. Where other fully condensing water heaters typically experience hot spots, this system eliminates them. The result is extended life of the product and maximized efficiency. The three-pass heat exchanger tubes are coated inside and out with a specially formulated porcelain enamel designed to protect against condensation.

Venting Options

With SPIDERfire ® you have a choice of venting. Installed with either power-vent or power direct vent. The power direct vent is the recommended choice where negative air pressure or indoor air quality is a concern.

More Venting Options (And Savings)

How? Because more heat is delivered to the water the flue gases are cooler. Cool enough to permit venting through standard PVC, CPVC and ABS pipe, which is cheaper than AL29-4C Stainless steel.

Multiple Water Connections

Water connections are easy with 2" NPT hot and cold water connections on both sides of the unit.

Smart LCD Control System

Standard equipment on all the SPIDERfire ® models is the new diagnostic system. It features a scrollable operational history and enables installers and service technicians to monitor key functions and components.

Faster draining and servicing

Factory installed full-port, full-flow brass drain valve.

Advanced Burner Design

Rheem has increased the burner surface are to provide ultra smooth ignition and quiet operation.

Direct Spark-to-Pilot Ignition Systems

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