Description

This High Performance Energy Saver series water heater provides incredible hot water delivery from a space saving, convenient package.

The Atmospheric Vent High Performance Model Features:
  • High Input Combustion System - Generates enough hot water in the first hour for hot tubs, garden tubs and body sprays in addition to whole house duty.
  • High Recovery and First Hour Delivery - When tested to the industry standard residential first hour delivery procedure, the GX2-25S can provide 155 gallons and the GX1-55S will deliver 200 gallons.
  • Integrated Mixing Device - Features an accurate, easy to use hand wheel for adjusting mixed water temperature, a pre-piped stainless steel flexible connector for quick installation as well as optional water connections (1/2" NPT recirculation inlet, 1/2" NPT hot water outlet, 1/4" NPT cold water outlet). This required system is easily installed and ensures a comfortable outlet temperature while providing a steady flow of hot water.
  • Helical Fin Flue - Designed to maximize the amount of heat transferred to water decreasing recovery time. Minimizes air movement in the heater during standby periods to retard heat loss up the flue.
  • Factory Installed Hydrojet 2 Total Performance System - Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.
  • Vitraglas® Lining - Bradford White water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The Bradford White high silica Vitraglas® lining provides a tough interior surface for the hot water tanks.
  • Fully Automatic Controls - Automatic temperature selection at your fingertips. Built-in energy cut-off switch prevents abnormally high water temperature for extra safety. Built-in gas pressure regulation.
  • 3/4" NPT Side Connections.
  • Non-CFC Foam Insulation - Energy saving insulation covers the sides and top of the tank, reducing the amount of heat loss while increasing jacket rigidity. GX-2 has 2" of insulation, GX-1 has 1" of insulation.
  • Water Connections - 3/4" NPT factory installed true dielectric fittings extend water heater life and eases installation.
  • Two Protective Magnesium Anode Rods - Provide added protection against corrosion for long trouble-free service.
  • 4" "Snap Lock" Draft Diverter.

Worked great for our needs.

Having added a bath to our master bedroom, the existing 40 gal water heater could not provide enough hot to our new jacuzzi tub. We looked at tankless options, but determinted an adequate tankless would surpass the capacity of our gas meter if run at the same time as the furnace. The GX-1-55S6BN met our needs perfectly. The tub is now at a perfect temperature when full. At installation, we did need to increase gas line diameter and vent liner diameter. The mixing valve was tuned at installation, and has had no need to be touched since. If you are remodeling an older 3-bedroom home and know you will have to increase hot water capacity for a master suite, definitely consider one of these high performance water heaters. Great performance and change in gas bill has been negligible.

Six years so far

We have used the water heater for six years without a problem. It is a better solution for us than having a standard, but larger, hwh, such as an 80 gal. Its commercially rated 80,000 btu burner will reheat the water in minutes, so the 1st hour supply is about 200 gal, enough for a large family.

Lots of Hot Water!

We bought this unit to replace our 20 year old water heater. We have a big whirlpool tub and needed more hot water capacity without the expense and complexity of a tankless on demand unit. This unit heats the water to a VERY hot temperature, then uses the included mixing valve to mix in cold water to bring the temp down. It works great, and gives us lots of hot water at the perfect temperature for long showers and filling that big tub. One other nice feature of the mixing valve is built in connections for a hot water recirculation system and a cold water tap for a humidifier line. My plumber commented on the high quality of construction compared to what's usually sold in home improvement stores. Bradford White is the way to go!

Water heaters with BTU input ratings above 75,000 do not generally have Energy Factor ratings, as manufacturers are not required to record them.
