Features

  • PRESSURIZED COMBUSTION SYSTEM: Exclusive and patented pressurized combustion chamber with an advanced air intake blower delivers superior efficiency. Much like a turbocharger, the blower distributes an optimum air-to-gas mixture pushing exhaust gases through the highly restricted flue baffle. The end result is the most efficient atmospheric gas product on the market with a .70 Energy Factor (EF).
  • INSTALLATION FRIENDLY: Allows for easy replacement of standard atmospheric vent heaters. Easily connects to existing B-vent.
  • FAN-ASSISTED, CATEGORY 1 APPLIANCE
  • 24V ELECTRONIC CONTROLS: Tighter differential for more consistent hot water delivery.
  • ELECTRONIC IGNITION: The durable hot surface ignitor eliminates pilot relight issues (no standing pilot).
  • LCD USER INTERFACE: Easy-to-read, eye level display. Simple temperature settings and adjustments. Service diagnostics are in plain text.
  • POWERED ANODE ROD: Powered anodes are non-sacrificial, so they do not deplete over time. Additionally, they provide exceptional performance in all water conditions.
  • MEETS ENERGY-EFFICIENCY REQUIREMENTS FOR MOST GAS UTILITY REBATE PROGRAMS AND MEETS ENERGY STAR® REQUIREMENTS
  • DURABLE TAMPER-RESISTANT BRASS DRAIN VALVE
  • DYNACLEAN DIFFUSER DIP TUBE: Helps reduce lime and sediment buildup, maximizes hot water output. Made from long-lasting PEX cross-linked polymer.
  • GREEN CHOICE® GAS BURNER: Patented "Eco-Friendly" Green Choice® gas burner reduces NOx emissions by 33% compared to standard burners and meets low NOx requirements of less than 40ng/j.

The AO Smith GAHH-50 Water Heater is a nicely engineered product (About the AO Smith GAHH-50)

Review by on Wednesday, October 29, 2014

After much research this water heater was the most cost effective unit I could find including tankless systems. My utility gave a $200 rebate. My family of 5 will save about $150 per year in natural gas cost compared to the 1990 unit it is replacing. The powered anode will save me about $100 every 7 years replacing anode rods. The 0.70 Energy Factor (EF) is amazing for a direct storage tank type replacement.
I love this unit but here are the things you need to know. The unit needs a 120 volt electrical outlet. I ran a dedicated circuit myself, permit plus materials $109. The intake blower is noise, my unit is in the garage and you can't hear it. If installed indoors it could be a problem. The 6 year warranty is short for a unit in this price range. So far my girls can't leave us with a cold shower, so if the unit holds up I WILL BE A VERY SATISFIED CUSTOMER

Damaged in shipping (About the AO Smith GAHH-50)

Review by on Saturday, August 9, 2014

I am a contractor and have purchased several water heaters from Home Perfect without problems. I failed to open the unit from the box for five days, including the weekend and when I did open it I found it to be damaged. I sent pictures to HP and was told it was too late as their policy was two days. I am stuck with a $800 unit that has no use to me as I could never install this unit in a clients home. Very disappointed in HP's decision not to give me an exchange.

Exceeded expectations (About the AO Smith GAHH-50)

Review by on Tuesday, February 12, 2013

I would buy my next water Heater from these guys in a heartbeat. Delivery was a little slow, but it's free, and i live across the country, so that was to be expected. The product showed up on a pallet, in great shape, and was exactly what I ordered. The picture shows a green blower on the side, and it's actually black, so that was a nice bonus. After a couple hours of having this unit running the hot water is working better than ever. The blower fan is loud though, so I would not use this unit inside the house.. I have it in the garage so i could care less. Not sure about the gas savings yet, but so far so far i'm really impressed. BTW - my last unit was an AO Smith and it was going on 20 years.. That is pretty solid for any water heater..
