surprised that i couldn't find any threads on this...
Background: I brew all grain and sometimes fill my HLT with hot tap water to expedite my brew day. I have an 80's style hot water heater at my house. It heats water on demand with a coil heating element inside the furnace. Water heaters like this are famous for collecting mineral deposits around the heating element over time. This is caused by the constant and consistent rapid heating and cooling of water inside the small reserve.
I notice that if/when I fill the HLT with hot water, it comes out very cloudy at first, which scares me. Maybe it's just from a residue on the inside surface of the pot, or maybe it's nothing. Other homebrewers I know have similar concerns so I was curious if anybody has ever looked into this.
I suppose one could also have similair concerns with using hot water that's been sitting in a tank. Fact is, it can really save you 20 or 30 minutes, but at what cost?
Perhaps, for a tankless heater, the answer is just to run your water until the small reserve empties?
