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 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
