Hot tap water?

[Barbarossa]

After thirty+ years in the industry (self employed over half that time) as a licensed plumber (specializing in service and repair) in three different states, I can say that some of the replies are a bit suspect, not enough to get your panties all bunched up but enough to cause a chuckle.

So, you are working in the industry, and you are telling people that drinking from the hot water tank is safe? Can't you lose your licence for something like that? Is this industry even regulated?

You didn't read past the first paragraph.

I would never draw water off the bottom of my tank type water heater to brew with, If the dip tube is compromised (happens all the time) then you are not circulating that tank completely with use, dip tubes are plastic and become brittle with time and will break off in the water heater as they decompose, water heaters can be a breeding ground, dark warm and stagnant. If you take a functually perfect fifty gallon water heater but only run about five or ten gallons of water a week through it, it will grow a nasty smelling black sludge in the bottom.

And you chose to ignore the followup information in other posts, are you trying to instigate an argument?

Problem solved! Someone mentioned making sure you have a flat bottom pot when using flat top stove. Time for a new pot!!

Alright!

That looks like some quite thin material too. That could become a potential scorch problem.
It's very possible they formed that recess to make the kettle more rigid, and prevent plopping when heated due to expansion.

Well, after reading through, I tossed 25L from my brewzilla that had been filled from my HW tank. It was up to mash temp quite quickly, but I figured better to be safe. I dumped into brand new white fermentation bucket. I should have taken a picture. The water was off coloured and full of organics and particles. Mostly likely from the brewzilla getting a cleaning, but still. My cold water source is visually perfectly clear.

Our hot water solar heated from the tank from the mains supply is crystal clear and currently at 77 celsius, this equates to 60 degrees at the tap in my brew room. Tastes fine and I just adjust it to dough in temp and add the salts and sod met.
Not sure whether I should get the water tested but the water company profile is pretty bland.

Good discussion here. I don't have anything to add from a professional point of view, but years ago I stopped using hot water for stuff like cooking (or brewing). I just noticed a few times with cooking pasta or boiling some canning jars that either the water (filled with hot tap) was either very cloudy looking or left a white film on the pot. I figure that the cold water is going to be a more consistent water profile.

Of course I flush my hot water heater regularly...let me just look up a video on how that is done.

I will say my coffee tastes better with cold water than hot water from tap. Partly due probably to high calcium left behind in the hot water heater
