Interesting video comparing big box store to supply house water heaters from same manufacturer.
Some comments from the video:
Supplementally- google/YouTube algorithms are beyond mind blowing, almost scary as they essentially read my mind. I have been looking to buy a spare AO Smith pro line 50 gallon natural gas water heater, in case my home unit failed. I have been studying the big box store exact model to see if they are the same. I only identified the drain valve and relief valve differences. I never told a sole or did a search on the difference, yet this video showed up on the top of my YouTube home page.
Some comments from the video:
- there are essentially only three manufacturers of water heaters in the world, the names are just relabeled (AO Smith, Rheem, and I forgot the third already)
- the video producer is a professional plumber, he is not unbiased in wanting the supply house water heater to be better
- some of the differences are irrelevant, like a plastic or brass drain valve (both should be replaced by a real drain valve when installing a water heater)
- some differences are notable
- burners are almost identical, and difference may simply be what burner was installed in what date
- ten pound difference in weight between the two perceived identical units
- anode rods are different, supply house magnesium (better), box store aluminum (only better to address smelly hot water)
- tanks empty (all components removed) have a weight difference, supply house tank weighs nine pounds/ seven percent heavier
- during a pressure test, the supply house water heater withstood more pressure than the box store water heater before blowing up (both performed poorly in this test)
- video is worth watching just for an education in water heater builds (I concede those with ADHD won't be able to sit through the video)
- yes there are a difference in this example between box store and supply house water heater. Not sure this finding is universal, and I suspect many times the difference is primarily a label and a different marketing material in the outside shipping box
