Hey gang....

I'm just toying with ideas to quickly heat up water (electric stove). I have a 10 gallon pot. right now just on my canning element (2600 watts) I can get 8 gallons to boil in about 1hr.

I have an idea to make a reverse wort chiller and send water through the oven , close to the broil coil to heat it up as it goes through the water heater coil into into the HLT.

Or while i'm mashing, get my next batch of water up to temperature faster in the oven. It's a higher wattage than my burners. Just help it to get up to the right temp faster than a range element.

Anyone have any tricks or thoughts?

Gas tank and outdoor gas burner will run your pot hot fast. If you want quick heat, that's your best option.

I almost always brew outdoors but I used a 110 heatstick to supplement my stove burner when I brewed a batch indoors a couple of months ago. I don't remember how long it took 7 gallons to get to a boil, but I remember thinking that it wasn't too bad. I had no trouble getting my sparge water up to temp during the mash.

I think a heat stick is much easier and probably cheaper than your circulate through the oven idea

Would the hoses withstand the broiler? (not sure how an electric oven coil sits)

Or, put 3 gallons into a stock pot on your next hottest burner, so you've got two burners heating your liquid at once. Dump it into the large pot once they're both boiling.

The night before I brew I always turn my water heater up to the highest setting. This makes the water come out of the tap around 155-160 I sparge with that water and you are that much closer to 212. It makes alot of difference when we're talking about heating up large amounts of water on brew day

cool thanks for the info guys... the coil inside the oven would come out of oven door so no hoses would be inside the oven. I'll just have to get a turkey fryer.

I see no way in which that could go disasterously wrong.

Other options include:

1. A heatstick.
2. An electric tea/coffee kettle (boil in small batches and add to the big pot).
3. Outdoor turkey fryer.
4. Vigorously rub the side of the kettle to generate heat.

It'll take much longer to heat it up in your oven vs. the stove, and the "reverse wort chiller" idea won't do anything for you. 1 hour to bring 8 gallons to a boil isn't bad at all for an indoor stove. The only practical way to boost it is a heat stick or using multiple pots like others suggested.

But really, that sounds like a good heating rate to me. My big old gas burner on my kitchen stove probably isn't even that good. Just plan your brewday accordingly; I like to measure out my strike water the night before, then wake up at 5 or 6AM and turn on the burner. Then I can nap on the couch while it's heating up.

From my understanding hot water from those heaters aren't technically considered potable. Bacteria can live in them if they aren't set properly, sediment builds up, the anode deteriorates, metals can leech in, etc...

Conventional wisdom is "don't drink hot water from the tap". It's perfectly safe to wash/clean/etc with, but generally not considered something you want to drink regularly.

I'd love to find a source for some harder data than "this is what I always here" but in the face of unknown I'll gladly just use cold water and heat it up.
