ProMax® Plus High Efficiency 50-Gallon Gas Water Heater

Model GVR-50

ProMax Plus High Efficiency Gas Tank Water Heater GVR-50 is rated 4.5 out of 5 by 8.
Rated 4 out of 5 by from Warranty Replacement for ProMax + The ProMax + GVR50/200 I installed 1/13/2011 began leaking at the bottom on 8/24/2013. The warranty replacement is a model GVR50/300 and appears to be better built. I had a Rheem 50 for 11 years before it began to leak and selected AO Smith based on having them in previous homes with no issues. I've installed over a 150 water heaters and prefer the AO Smith brand.

Rated 4 out of 5 by from Good basic water heater Seemed to be the most energy efficient heater that did not require electric power.

Rated 5 out of 5 by from Replacement water heater I bought this AO Smith water heater because my original water heater was an AO Smith.  The original was still working good, but being 15 1/2 years old, I thought I would be proactive and replace it before we woke up to a cold water shower one morning.  If this one works as good as the previous AO Smith, I will be pleased.

Rated 5 out of 5 by from does a great job for us, as I knew it would Bought machine on internet. Have used AO Smith for 50 years and never had a problem, A 6 year warranty machine 13 years old, installed new heater because of age and not wanting a flood if it sprung a leak. It was an easy install for me as I have done 6 others in my life.. Makes a bit of noise when metal expands and contracts , but otherwise great. It is in utility room and can't hear it elsewere. Glad I bought it!

Product Features & Options

Electronic Gas Control

Intelligent control logic provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance.

Diagnostics

The electronic gas control incorporates an LED status indicator that monitors system operation and service diagnostics.

CoreGard™ Anode Rod

A. O. Smith’s exlusive aluminum anode has a stainless steel core, which protects the tank against corrosion longer than ordinary mild steel anodes.

Brass Drain Valve

Our brass drain valve is more durable and tamper-resistant than an ordinary plastic drain valve, which contributes to improved safety and reliability.

How it Works

Gas water heaters heat water by burning either natural gas or LP (propane). Gas water heaters need a source of air and also need to be vented properly. Cold water enters the water heater through an internal “dip tube” which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection. This arrangement provides the most hot water for a given tank size. Most gas water heaters use a pilot light. The pilot light on some models also generates the power needed to operate an electronic gas valve. When cold water enters the tank, the temperature sensor on the gas control tells the main gas valve to open. Gas flows to the burner where it is lit by the pilot light. The air needed by the burner is supplied by the room where the water heater is installed. The exhaust gases are vented to the outside. When the proper temperature is reached, the main gas valve shuts off. Because water can corrode the steel tank, we glass line the inside of the tank and install an anode rod to help reduce corrosion. The temperature and pressure relief valve is a safety device designed to open if the internal temperature or pressure of the tank exceeds certain limits. Water heaters should be large enough to provide adequate hot water even when temperatures are cold and household demand is greatest.
