I usually use cold tap water in my electric HLT for brewing but it is taking close to 2 hours to heat up 10 gal. for my sparge water. Any reason I couldn't just start with hot tap water and heat that to 175? I'm guessing hot tap water may have a bit of Mg from the anode but that might be better for yeasties anyway. I'd like to get the sparge heating time (which is my mash time) down to around 60 min.

It's 2000w in a 10 gal Rubbermaid beverage cooler. The cold tap water is 55deg right now which doesn't help.

I use hot top water to begin for both mash and sparge water. Makes the heating process a lot faster (I use propane). Depending on your water, the minerals in it can certainly be good. My water is very soft. I can go from there.

I don't see any difference heating the water in the hot water heater or in the cooler. I say go for it.

Im no expert so take it for what it's worth but I would sure use hot tap water to get a jump on heating brewing water if I were in your situation. It looks like that would put you rite around an hour on your sparge water heat up too. The only thing you can do is try it and see if it works for you. Hope this helps

PRE BOIL ONLY.....

Hot water tanks contain tons of bacteria that can withstand pretty high heat.

I also wouldn't use hot tap water. Hot water tanks accumulate mineral buildups, so the water coming out will be harder and of a different profile than your cold tap.

Wouldn't the boiling process take care of most of that?
