The water from your hot water heater in not good for sparging.

Why not?

Is there something that make the water unsuitable or are you thinking of the temperature?

If the temperature is the concern, I think the poster was talking about starting to heat from the hot water heater is quicker than cold water.

I guess it's the minerals or something.
I just remember asking the same question, and getting several responses that the water was not suitable.
I guess I should have remembered why, so I could have a better response.

Hopefully someone will chime in that knows the answer.

I'm interested in how it would be different than what we are doing with water heater elements in our HLTs?

It depends on the water you are using. If you have high calcium or iron or other undesireables in your water they can accumulate in your household water heater and give slightly higher concentrations than the cold tap.

Personally, I haven't messed with testing/treating my water. I brew with softened well water that I know isn't perfect, but neither is the rest of my process.

I think the argument goes something like this: That water has been sitting around hot in the tank for a long time, maybe as much as a day. It would have had plenty of time to leach out bad stuff, like led and other things, from the tank and from the hot water pipes. I suppose there could be bacterial infection as well, I don't know.

I have tasted hot water from the tap and I think I can pick up a mineral undertone. I suppose different installations will have different results.

I've looked over this thread many times, and in fact built a nice system nearly identical to it. Alas, my element has burnt out after a few months. I had bought it from Lowe's, so who knows if it was low density, but it seemed to do fine without scorching. My question today is what should I replace it with? Does anyone know of a low density 2000W 120V element?

I use the 1500W LD element from Plumbingsupply.com. It works fine.

According to the people who installed my water conditioning system the hot water from the water heater might have a number of problems.

1. Excess aluminum or magnesium from the anode. If your water is reactive in any way it will contain minerals from the anode that were dissolved by electrolysis to prevent corrosion of the tank and fittings.

2. Hot water tanks quite often have sulfur reducing bacteria as it is a good environment for them.

3. Most minerals concentrate near the bottom of the water heater, changing the entire mineral balance. This may be good or bad, depending upon what beer you are making.

As a test, pour a glass of water from the cold tap, one from the hot tap and one from the drain on the hot water tank. Cover them and let stand a couple of hours. Look for dissolved gas coming out of suspension. Then taste compare the three samples. Make up your own mind as to which samples are acceptable to you for brewing. Personally I can taste quite a difference and choose to use only cold water in my brewing.

All makes sense. Sorry for dragging this thread so far

This is a great thread so I suggest we try to get it back on track.

Thanks for all the replys. Sorry for the diversion Guy.
