75 Gallon - 76,000 BTU High Input Atmospheric Vent Energy Saver Residential Water Heater (Nat Gas)

The Bradford White RG275H6N is a 75-gallon residential natural gas water heater engineered to deliver consistent, high-volume hot water for homes with 5 or more occupants. With a 76,000 BTU input and atmospheric vent design, this unit provides an 80% recovery efficiency and rapid heating performance that keeps pace with heavy household demand. Built around Bradford White's ICON System (an intelligent gas control powered by millivolt technology with a built-in piezo igniter), the RG275H6N combines proven reliability with enhanced temperature precision, making it a professional-grade solution for contractors and homeowners who need dependable, long-term water heating without external power dependency.

• ICON System Intelligent Gas Control: Microprocessor-controlled burner operation maintains tight temperature differentials and consistent water temperature, while the millivolt-powered design requires no external electricity to operate. You get reliable hot water even during power outages, plus enhanced first-hour delivery ratings and precise temperature management.

• Hydrojet 2 Total Performance System: Factory-installed cold water inlet device reduces sediment buildup in the tank and increases first-hour hot water delivery. This extends tank life and maintains heating efficiency over years of use, reducing maintenance frequency.

• Vitraglas Tank Lining: Exclusively engineered enamel formula fired at over 1,600°F fuses to the steel surface, providing superior protection against corrosion from hot water exposure. This premium lining extends tank lifespan and protects your investment in high-demand residential applications.

• Separate Immersed Thermowell: High-strength advanced polymer composite thermowell isolates the electric temperature sensor from surrounding water, allowing gas valve removal without draining the tank. Service and diagnostics become faster and simpler, minimizing downtime.

• Non-CFC Foam Insulation: Covers tank sides and top (1.25 inches thick on this 75-gallon model), reducing heat loss and improving operational efficiency. Lower standby energy consumption translates to reduced utility costs over the heater's service life.

• Diagnostic LED System: Green LED light provides positive pilot-on indication and offers ten diagnostic codes to assist troubleshooting. Installers and service technicians can quickly identify issues, reducing callback time and repair costs.

• True Dielectric Water Connections: Factory-installed 1-inch NPT fittings extend water heater life by preventing galvanic corrosion and simplify installation. These connections are compatible with both copper and PEX plumbing systems.

• Tamper-Proof Brass Drain Valve: Ball-valve design (not faucet-style) provides reliable drainage and sediment flushing. The robust construction resists damage and ensures long-term serviceability.

This water heater requires a 1/2-inch natural gas connection and a 4-inch vent size for atmospheric venting through a lined masonry chimney or approved venting system per local codes. The unit features 1-inch NPT water connections and includes side-mounted 3/4-inch NPT tappings for space heating applications (potable water only). The RG275H6N operates without external electrical power, relying on millivolt energy from the pilot flame. Installation requires compliance with all manufacturer specifications and local plumbing and building codes.

Installation must be performed by a licensed professional in accordance with the provided installation manual and local ordinances. The unit must connect to a lined masonry chimney or approved venting system, and the 4-inch draft diverter (included) must be installed per manual instructions. The water heater ships with a factory-installed T&P relief valve. Regular maintenance includes periodic draining through the brass drain valve to remove sediment, annual inspection of the protective magnesium anode rod (replaceable via the separate hex-head access), and visual checks of vent connections and burner operation using the diagnostic LED system.

A: Bradford White 75-gallon residential water heaters are designed for extended service life when properly maintained. The RG275H6N features Vitraglas tank lining (fired at over 1,600°F for superior corrosion resistance), a protective magnesium anode rod, and a Hydrojet 2 system to reduce sediment buildup. Regular anode rod inspection and replacement, combined with periodic tank flushing, are critical to maximizing lifespan. Customer reviews report Bradford White units lasting 20 years or more with proper care, though the manufacturer provides a 6-year limited tank warranty.

A: Installation costs vary based on local labor rates, existing plumbing and venting infrastructure, permit requirements, and whether upgrades (such as gas line sizing or vent modifications) are needed. The RG275H6N requires professional installation by a licensed plumber or contractor, including connections to a 1/2-inch natural gas line, 1-inch water lines, and a 4-inch atmospheric vent system approved by local codes. Factor in additional expenses for accessories like expansion tanks, water heater pans, and compliant venting materials when budgeting for the project.
