I was so surprised just the other day, when walking into the mechanicals room of two - not one - two different homes - to find a different looking hot water heater.... I am used to the round tall ones that hold anywhere from 40 gallons to 80 gallons.
Lo and behold they now have square ones! Two houses in a row!! Whaaaat? I do not know if they are cheaper, more expensive, better quality, etc. But they sure are different.
Hopefully, one of our favorite inspector friends will stop in and tell us all about it.
