Which is best gas water heater for homeowner/ things to consider
Water heater label 1) Check label on side of old tank
    Gallons and BTUs of old water heater.
    NG natural gas or LP propane gas > these are two different water heaters
    Measure height if necessary.
Natural gas NG
or
Propane LP
Propane water heater not recommended below grade (in basement)
Propane gas is heavier than air, so gas leak hugs floor and can fill basement with explosive gas.
Natural gas is lighter than air, and will rise.
Odorant is added to gas. If you smell gas, leave house immediately and call gas company.
TP valve
How to replace TP valve
2) Check if TP needs to be specific height

Important if overflow tube goes through a wall or cannot be moved.
TP overflow tube must drain downward, and cannot tip upward.

3) Air intake on bottom/ Best choice

AO Smith, Kenmore, Whirlpool, State, Reliance, Craftmaster, American etc. / Service manuals available
Choose water heater with air intake on bottom so air intake screen is easy to clean.
Set 3-legged water heater on bricks so air intake screen, or flame arrestor screen, can be inspected and cleaned.
Buy from local box store or hardware. Offer 10% off.
Shorter warranty is better warranty-value.
6-year water heater that is maintained will last longer than 6 years.

Water heater air intake

Air intake on side of tank/ maybe not best choice

Rheem, Reliant, Ruud, GE etc
No service manuals
Air intake on side of tank means that combustion parts have to be removed to clean air intake screen, or also called flame arrestor screen.

If arrestor screen becomes clogged with dust, the amount of air entering combustion chamber is reduced, and this slows draft going up vent pipe, which causes slow draft, vent odors, sooting, possible danger from incomplete gas combustion, and eventually causes combustion chamber to overheat, which trips FV lockout system. Repairs required. Keeping arrestor screen is important, so choose water heater with screen located on bottom of tank where it is easier to inspect and clean.
Flame arrestor screen
Air intake screen
Same as: Flame arrestor screen. Must be cleaned periodically > applies to all brands gas water heater.
Manufactured home water heater air intake

Manufactured home/ Small unvented closet/ Small home

Mobile home water heater is designed to draw air from underneath structure.
This ensures adequate air supply to support combustion, and allows water heater installation inside small closet.
Air intake must be kept clean, and no flammable vapors stored nearby.
Spec sheet illustration of air intake

Install electric insted?
Note: any ordinary electric water heater can be installed in mobile home when circuit breaker box can support rated wattage.
4500 watt electric water heater = 10 gauge wire and 240volt 30 amp breaker
Replace elements with smaller wattage

3800 watt electric water heater = 12 gauge wire and 240volt 20 amp breaker

Warranty

Which water heater is best

4. Warranties are same across all brands

First year parts-tank-labor are covered for original homeowner and non-commercial installation
when installed by instructions shown in product manual.
Some sellers cover labor for installing new heater during first year. For example Kenmore.
After first year, parts-tank are covered, but no labor.
Some newer warranties are pro-rated, and do not give full coverage for tank as it gets older.
Math shows that shorter warranty has greater percentage of full coverage.

Should you select 6 year 9 year 12 year?
Only difference is anode rod diameter, or sometimes 2 anode rods.
You can convert 6 year tank into 12 year or 15 year by inspecting anode each 1-3 years, and
maintaining tank as shown in product manual.
How to Replace-anode-rod.html

Extended warranty
Some stores offer extended warranty. Do not buy extended warranty unless it also includes labor.

5. FVIR prevention and resettable TCO

Today's gas water heaters need regular maintenance and plenty of fresh air to avoid FVIR and ECO shut-off problems. Clean air intake screen regularly. Do not expose water heater to flammable vapors, or dusty environments. Keep belongings away from front and top of water heater. Read the manual and avoid problems that cost money and shorten life of heater.
The more you can do yourself, the lower long-term cost.
FVIR= flammable vapor ignition retardation. ECO = energy cut off. TCO = thermal cut off.

Bradford White has FVIR resistant water heater that can be reset or repaired after FVIR event. Service manuals are available.
AO Smith American State Reliance Craftmaster Kenmore Whirlpool have FVIR resistant water heater that can be reset or repaired after FVIR event. Service manuals are available.
Some Rheem, Ruud, Richmond, GE water heaters can be repaired and older models need to be replaced after FVIR event. No service manuals are available.

Always turn off water heater when painting or working with fuels
Make sure water heater has adequate air supply. Avoid dusty atmospheres and exposure to clorox and pool chemicals.
Clean air intake yearly and clean combustion parts frequently to avoid ECO shutdown caused by overheating.


6) Smaller is better if you reduce consumption
Choose right size
Oversize tank cost more to operate. Undersize cost more in repairs.
Resale of house might require minimum 40 gallon size
Oversized bathtub: buy minimum 50 gallon gas water heater or 60 gallon electric

"Energy Factor indicates combined thermal efficiency and standby efficiency of a water heater."
Energy star gas water heaters 2012
You can reduce greenhouse gas with higher energy factor > BUT< if water heater has elaborate design, then repair costs outstrip savings. All costs are energy.
Estimated annual cost of running gas water heater/ pdf
Water heaters with 'high recovery,' and 'high first-hour delivery' consume more fuel per minute of operation and have lower or non-rated energy factors.
-Small simple gas water heaters heat 41 gallons hot water per hour.
-Shower uses 7 gal hot water. Bath uses 15 gal hot water.
Repair tankless water heater 8) Avoid tankless promotion
Typical family, tankless save $1-8 on monthly energy bill, but installation, maintenance, repairs and purchase price never payback. Tankless are maintenance heavy.
All costs are energy. Read1 Read2
Tankless require yearly maintenance, tank-type require periodic maintenance
9) KEEP IT SIMPLE: Expensive water heaters will not pay pack

Things you should ask before buying solar water heating system
water heater safety precautions
Do not set gas water heater on carpet or near flammables
Cautions:  
Do not install GAS water heater on top of carpet. Must be on wood or metal surface.
  Keep household and building materials 6" away from front; 0-1" away from side and back; and 24" away from top of water heater.

Check that water heater is NG natural gas or LP propane gas > these are two different water heaters   
Do not install LP gas water heater below grade (basement) since gas leak will fill basement with explosive gas.
NG is fine for basement since NG natural gas leak is lighter than air and will rise, so basement will not fill with gas 
     Gas water heater should be set 18" above floor level. Adequate incoming air supply is needed.
    Do not install LP gas water heater below grade (in basement).
Read water heater safety precautions before starting

Installing new gas water heater


Cold side has shut off
Run water and feel which pipe is hot
Installation starts here

1) Identify hot and cold.sides
Look for markings on top of old tank. Letters H and C are usually stamped into top of tank.
New heater must be connected Hot-to-hot and Cold-to-cold.
Shut off valve should be located on Cold side. But never ASSUME... always check Hot and Cold sides.

1) Turn off water Notice that shut off valve is located on COLD water pipe.
Hot pipe must go to side of heater marked HOT, and cold to COLD or heater will not work.
Disconnect water pipes from water heater.
If you are unsure which pipe is hot, then run hot tap for a minute and feel which pipe on top of water heater is hot
water key No shut off valve
Shut off water to house
Rotate shut off 1/4 turn so valve is perpendicular across water line

Located water meter box, remove lid, dig away dirt to find shut off
Shut off is located on house side of meter
Use water key or pipe wrench
clean out water heater tank
Drain water heater
2) Drain old water heater using valve at bottom of tank. Air must enter tank to drain water. Open TP valve or open tub faucet on hot side.

Install new heater so hose can connect to drain
Flush open water heater
Water-heater-will-not-drain
Turn off gas valve
Turn Gas valve OFF

3) Shut off gas
Locate gas line.
Gas line is black-colored metal pipe or a yellow-colored flexible tube.
Follow gas line back a few feet away from water heater and find gas shut-off.

When gas is ON, handle is positioned same direction as gas line. To turn gas OFF, rotate shut off handle 1/4 turn.
When shut-off handle is perpendicular across gas line, then gas is off.
Gas valve is ON
gas line to water heater
Keep end of pipe clean
4) Disconnect gas line from water heater control valve using crescent wrench or pipe wrench.
Keep end of gas line clean.
If you have flexible gas line, take care not to twist or kink tube so you can use it again. Spray a bit of WD40.
Note size of gas line: If you buy same BTU heater, then gas line is correct size.
If you buy heater with more BTUs, check that gas line is large enough.

Tip: Home center sells yellow-colored flexible gas line. Back of flex-line package has BTU chart to help select correct size gas line. New flex gas line can cost about $30 so use old one when possible.
Black pipe union
Black pipe union
Keep pipe clean
Union
Gas line, and water lines can be connected with UNION.
Loosen large nut. Take apart union using two wrenches.
Re-install union:  Clean connection surface with rag and apply thin film of approved pipe sealant to each surface using finger to help pick up last bits of debris and to help seal pipe.
No teflon tape needed on threads of big nut.
Keep parts clean so debris does not enter gas control valve
-or- replace union with flexible connection.
Disconnect vent pipe
5) Disconnect vent pipe from draft hood
Support vent pipe with wire so it will not fall down.
Flue pipe joints should have 3 sheet metal screws at each joint.

Purpose of vent pipe is to remove combustion gases from house
Flue pipe hazard 6) Inspect vent pipes/ Do not use aluminum vent pipe
Vent pipe must be approved material as shown in product manual. For example galvanized or stainless steel.
Aluminum vent pipe is not code, and is unsafe.
Install 3 sheet metal screws per joint, and then add metal tape over screws if required by local code.
Taping vent joints without using screws is not code.

If vent pipes are rusted, or covered with white condensate, or have holes, then vent pipes must be replaced.
If top of old water heater has black soot, that can indicate vent pipe is not working correctly. Danger.
A plumber may be necessary to correct vent problems.
Check that vent cover is still on top of vent pipe located on roof and that vent pipe has no obstructions.
Read more near bottom this page.
Test water heater vent pipe 7) Check if vent has proper draft by lighting match

See if smoke drafts immediately upward.
The smoke should not linger. It should draw upwards quickly.
If vent does not have draft or if furnace vent is blowing out of water heater vent each time furnace turns on, then vent pipes must be repaired.

All gas appliances must vent out of house to avoid CO poisoning.
Read checking the draft
8) Move old water heater out of way.

10) Set new water heater in place
Read manual for advisories.
Water heater should sit at least 18" off floor since flammable vapors, such as stored lawn mower gasoline and paint thinners, will gather close to floor.
Leave space so water hose can be connected to drain valve.
Water heater weighs 75-220 lbs empty. 40 gallon steel water heater filled with water weighs approx 400-500+lbs.

If area is prone to high water, set heater higher.
Warranty is void if water heater floods. Manufacturers recommend replacement of flooded heater. Do not touch water heater that has been flooded. Electric shock danger. Turn off breakers.

Use earthquake straps as required by code.
Earthquake straps at Amazon

Set water heater in drip pan.
If air intake is on bottom, then stand heater on bricks.
Drip pan cannot be deeper than 2", and must be 1-2" wider on all sides than water heater so the pan does not interfere with air supply entering water heater. Install 3/4" or larger drain connection that goes to a drain.
Many people don't use drain pan. Tank failure can render home unlivable until repairs are made. Leaking water heater

12) Attach vent pipe to draft hood using 3 sheet metal screws per joint, and then add metal tape over screws if required by local code.
Taping vent joints without using screws is not code.

Vent must fit over draft hood and be attached to draft hood with screws
See more images further down on page.

3" vent hood Vent hood on new water heater and vent pipe diameter must match

Most residential water heaters use 3" diameter vent pipe.
Some higher-BTU water heaters require 4" vent pipe
Some local codes require 4" vent.
Do not use 3" vent pipe on 4" draft hood. Larger vent is ok.
solder 12a) Solder for copper water pipe
Use 95/5 tin-antimony solder or other equalevent when soldering copper water pipe.

Use PTFE yellow teflon tape on gas pipe joints
14) Connect gas line exactly as it was connected before.
      Apply yellow teflon tape, and leave first two threads clean with no tape.
Do not let dirt, stray teflon, or any debris enter gas line. Make sure gas line is clean.
If you can install water line successfully, you can connect gas line. Gas line has less pressure than water line.

When using pipe joint compound, use approved compound for gas. Do not over-dope pipe so compound can enter gas control valve.
Make sure inside diameter of pipe is clean and free of cuttings and loose dirt.

Don't overtighten gas line to gas control valve or damage to gas control valve can occur.
Gas line connection
Do not overtighten
       Re-use yellow flexible gas line
If product manual requires solid pipe, do not use flexible connection.
For example hybrid, or tankless ect might require solid pipe.
Local code might require solid pipe, otherwise flexible gas line is easier to install.
Do not use copper pipe for water heater gas connection. Gas will react with copper. There are regional exceptions that allow copper pipe, when the regional gas supply does not react with the copper. Check local codes.

Use yellow teflon tape on flex line connections
Home center sells flexible gas line for easy installation.
Back of flex line package has BTU chart. Match flex-line diameter with BTUs of new heater.
Do not overtighten at gas control valve

water heater overflow tube
Install overflow tube
15) Install TP overflow tube that runs down to at least 6 inches of floor.
Use pipe off old heater.
Overflow tube must be same diameter as valve discharge connection. Do not downsize pipe into smaller pipe. Overflow tube can have maximum 4 elbows and 30 feet length.
End of overflow tube cannot be threaded.
Tube cannot be lower than top edge of drip pan. Tube must terminate 6" above open drain. TP valve can draw water back into water heater if overflow tube is under water.
Do not cap off TP valve or obstruct overflow tube
Overflow tube cannot have shut off valve installed, or any obstructive valve
TP valve is first line of safety for water heater.
TP valve releases water when pressure or temperature is too high, and prevents possible water heater explosion
How to test and replace TP valve
Install gas water heater Tank is installed
Water heater set 18" above floor in drip pan
 Vent hood and vent pipe connected with 3 screws at each joint. Aluminum tape over each joint.
Water pipes installed
Gas line connected to water heater control valve.
Overflow tube connected to TP valve

Next:
Turn on gas
Check for leaks
Fill tank with water
Turn on burner
15a) Water heaters that connect to electrical outlet.
If water heater has power vent blower etc, it will connect to electrical outlet. Use surge protector. New gas valves and electronics can be damaged by simple power outage. Surge can happen when power resumes. Outlet surge
  Whole house surge
Outlet must be wired correctly, with correct polarity and ground. See chart
Best result is dedicated outlet that does not connect to other circuits inside home, and does not have fluorescent lights on same circuit.
Use cheap circuit analyzer from hardware to test outlet. See image
Use multi-meter and test continuity between manifild tube on gas control and ground prong on plug.
Gas controls are damaged by surge: Use surge protector.
Gas valve is ON
Gas valve is ON
16) Turn gas ON
Rotate gas shut-off handle until parallel with gas line. This lets gas flow to water heater control valve.
Now that gas is ON: 
NO SMOKING, no flame, do not turn light switch on-or-off
OK to have lights ON, just don't turn ON any other electrical appliance until leak test is completed
You can easily smell gas. LP gas is heavier than air, so smell close to floor. NG is lighter than air and will rise.
Be prepared to leave house immediately if you smell gas.
Lp gas falls to floor level, so smell close to floor. NG rises so you can smell NG leak when standing.
Do not worry excessively
Test for gas leak
Larger image
Give gas time to show bubbles.
Gas pressure is low, so it take time for leak to show.
17) Test for gas leak
a) Test pipes: Mix liquid soap with water and use brush to put around around gas line joints to see if there are bubbles. Use plenty of soapy water. May take some time for bubbles to appear since gas is under low pressure.
Soap bubbles coming from joint indicate leak: retighten pipes, use teflon tape on yellow flex pipe and black pipe.
Do not overtighten pipes or damage can occur to gas control valve.

b) Test factory-installed connections located below gas control valve
Manifold and pilot tube connections located under the gas control valve do NOT use teflon tape.
See image of manifold and pilot tubes
If either tube under gas control valve is leaking, just tighten a little bit. Do not overtighten.
Manifold and pilot tube: look for reverse thread on LP water heater. Regular thread on NG water heater
Remember: Natural gas and propane gas both have less pressure on the line than water pipes, so gas pipes are easy to seal with ordinary wrench. If you can install water line without leaking, you can do the same with gas line. Do not over-tighten connections.
Gas odor will be present if gas line has leak. Smell close to floor since some gas can be heavier than air and will settle downward. If gas is present, leave house immediately and call gas company. Turn off main shut-off at gas meter.

Bathtub running full stream before lighting water heater
Tank must be full of water or steam explosion could occur!!

18) Fill tank completely with water until water is coming out of tub spout.
Open tub spout on hot side and wait for full stream of water.
Next open TP valve for a moment to bleed last of air from tank.
Turn off tub spout and light heater.
Tank cannot have any air when burner is turned on or damage can occur to tank.

How to light typical gas water heater
Read directions printed on side of your tank
19) Light new water heater as shown in water heater manual
Read product manual for tips and advisories.

How to light gas water heater by type of gas control valve
Note: New gas heater might have small water leak when first fired up because of condensation
Ignore a bit of water inside combustion area or bottom of tank.
This water is condensation and will disappear as tank reaches set temperature.
Any cold tank can show same condensation when fired up.
Water pipes should not be leaking.
Water should not be dripping down vent pipe: this signals bad venting ot other vent problem.
Don't worry excessively, but if needed, post questions on professional water heater forum: The Tank

Flue pipe safety
See larger

During typical water heater combustion, hydrogen content of fuel is burned and the result is hot gases. One of these hot gases is steam or water vapor. Adequate venting or air draw up vent is required so gases vent outside. 
When there is inadequate draw, the water vapor cools and condenses on inside wall of vent pipe. This condensation water is acidic (pH 3-5) and corrosive. It will corrode steel metals and other materials.
Improper venting causes water to drip down vent into combustion chamber of gas water heater. Parts inside combustion chamber rust. Holes develop in bottom of water heater. Inspect combustion chamber for rust and water.

If steel vent pipe is not venting, the vent pipe will rust and get holes, or joints will fall apart. This situation causes hot gases to enter home and poses serious risk of odorless CO poisoning.

Simple test for proper venting: Pipes are not rusted or covered with white condensate. No water on top of tank. Burner inspection does not show excessive rusting. Light match under vent pipe and see if smoke immediately draws upwards. If smoke does not draw, then call plumber.
Flue Pipe Safety
Read manual for flue pipe clearances so hot vent pipe does not touch or come near combustibles.
Rusted flue pipe -or-water on top of gas water heater could indicate serious problem.
Call a plumber if you are uncertain.
Check pipes and flexible connectors for leaks.

If water coming from flue pipe:
1. Vent cover could be missing > rain water entering flue (replace cover)

2. Flue pipe clogged with bird nest or come apart or damp from improper venting: danger of odorless Carbon Monoxide poisioning

Serious danger from CO poisoning, a plumber should be called if you are uncertain about vent pipe water leak
