So i do not have access to a 240V outlet, so I was wondering if you think it would be ok for a Electric Brew Kettle if I used two 120 V heating elements (mind you this is for 10 gallons). The way i figure is i wire them each to separate switches and turn one of them off when the hard boil beings to prevent scorching.

I figure in the HLT 1 120V element should be ok. Does this seem reasonable?

You'll need to run those on separate circuits, and depending on your kettle geometry, you can run the full wattage during boil.

I boil 5 gal with 1x3000W element in my kettle for a rolling, but not vigorous boil.

Say you find [email protected] elements (I think you can run a [email protected] element at 120V, but I'm sure someone else will pipe in and tell you why I'm wrong). Note (edit): [email protected] is actually [email protected] (same element).

[email protected] is 12.5A. Most household circuits are 15A, so you'll need two circuits to run a pair of 1500W elements.

I am not positive, but for some reason I think your get 1/4 of the watts when you 1/2 the volts. So a 3000W 220V becomes a 750W 120V

I say use the 2000 watt 120v element.

$9 each

Scoates, if you have a 3000w Element @240v it will be less than 1500w at 120v. It's an Ohms law thing, but that does not mean you can't get a 1500w element @ 120v. S.

1920w is the max on a twenty amp circuit. This is because heating elements are continueos loads. So the circuit must be derated to 80% of the maximum. The reason is that running full bore causes excesive heat in the breaker and the wire, eventualy causing tripping and other bad JUJU.

Such as living in the Best Western down the road while the inspectors figure out whose fault the house fire was.

You'll rarely find a 20 amp circuit regardless. They are usually only found where a floor buffer is used and have the horizontal plug in addition to the verticals . If your hoping to do long term brewing, it'd be easier to install, either yourself or by an electrician, an extra circuit for brewing purposes.

That way you avoid a fire risk and don't have a circuit trip in the middle of brewing....especially if the lights are on the same circuit.
