Keeping the water temperature above 150 degrees should ensure no bacteria can grow, but if you have small children or elderly people in the home, this may not be a viable option due to the risk of scalding.
    I believe this is inaccurate advice - nearly all water heaters have a maximum temperature of 140 degrees, since 125 is scalding. Very rare for bacteria to grow inside a water heater unless IT sat for many many months without being energized and heating. Many times, just running the tank until cold water is felt through a tub faucet will flush all the sulfides from the tank that have occurred with reaction to the aluminum or magnesium anode rod. There are only 4 manufacturers of tank type water heaters in the USA - AO Smith or State have the best reliability in my opinion - DO NOT buy a Craftmaster or any heater with a high limit switch for the new enclosed burner systems - complete garbage... If you go with tankless - get a Japanese made instead of Korean or Chinese, which have inferior electronics... I hope this helps. Friendly Home Services Baton Rouge...

    Corrections to some inaccurate statements.

    1.Aluminium Anodes Rods actually reduce the effect of sulfur reducing bacteria in glasslined tank type water heaters. Both magnesium and aluminiun are used depending on the area of the country if possible. Finally 9 and 12 year heaters absolutely have larger anodes than 6 year products.

    2. It depends on the water chemistry how bad the oder is. Chlorinating can help, but not all the time.

    3. There are three manufacturers of tank type water heaters in the US. There are other labels, but mostly made by AO Smith.
    AOSMITH (Brand names: AO Smith,State,Kenmore for Sears, Reliance,Morflo, American,GSW/Canada and Lowes under the Whirlpool Label)

    RHEEM Manufacturing Company.( Brand Names: Rheem,Ruud,Richmond, General Electric for The Home Depot,Vanguard for WW Grainger)

    BRADFORD-WHITE. (Wholesale Only)

    4. Electric Water heaters are factory set at 120 degrees by regulation. Thermostats can go from 70-150 degrees on residential heaters.

    5. Residential Gas Water Heater Thermostats are set at off and have a range from 85 to 160 degrees.

    6. Serial numbers on all Rheem built product have the month and year it was built as the first four numbers of the serial number.
    There is also a manufacture date clearly displayed on the rating/data plate.
    7. AOSmith uses a letter for the month and a number for the week when it was produced.

    Hope this helps clarify some facts and figures about the water heaters.

    There are multiple issues with that installation:

    1) The Rubber Hose on the Hot Side needs to be eliminated and piped in properly...

    2) The rust drip appears to be coming from the T&P Valve, which needs to have a Metal Drain Pipe connected and terminate within 6" of the ground, since the heater is already "outside"...

    3) Brand New water heater should not have any dents in the jacket - that kind of damage means to me that heater was very possibly dropped...

    4) The water lines coming and going are only 1/2" copper, likely tied to 1/2" galvanized piping below where your picture shows. The Cold Supply and Hot Feed should be sized up to 3/4", which will give you more Water Volume (not pressure)...

    5) The 3" Flue/Vent Pipe needs to be extended to go out the roof of your shed...

    6) If this was a "licensed" plumber who installed this, they need a spanking...

    You left out Amercan, maker of the Whirlpool brand.
