I know people do it everyday...but personally, I do NOT like to have the water tank shut off for an extended time. This can in some instances, (and I have seen it) cause a biofilm growth.

You can still click on the article, it will come up.
IThe other more contentious issue would be the temperature setting. The Villages sets the tank temperature at around 120 degrees, for fear of scalding. I personally feel more comfortable having the temperature a bit hotter to kill bacteria.....but that is just me.
II know my opinion is in the minority here.....just my two cents and it did not cost anything....Enjoy!

It doesn’t do anyone good to spread factoids on matters of public health if they cause panic by being incomplete. The linked article is inaccurate by omission. Legionella bacteria, if it exists in your water system (which is extremely unlikely) is killed by a hot water tank in 32 minutes. Source:
Hot Water Heater Safety & Temperature: Legionella Prevention. You will note your temp should be set at 140 degrees. That is always the case to avoid this bacteria, if you have left for vacation of not.
The topic of the post is should a hot water heater be turned off? Yes or no it is your choice, however it should not be left of for fear of legionella bacteria.
Simply turning on the heater and waiting an hour before use is fine for the purpose of killing bacteria, if it exists in your hot water heater.
