Water Heaters


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

  • 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 from130,000-399,900 Btu/h, with a maximum temperature setting of 185 degrees.

  • 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.

  • 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.

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

  • Hot and cold water Inlets and outlets on both sides of the unit provide installation flexibility.

  • Factory installed brass drain valve allows for faster draining and servicing.

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

  • Certified up to 8,999 feet

  • CSA/ASME Rated T&P Relief Valve
