2 x 1500 watt 120 v elements enough for 10 gallon batches

I looked all over.

Kal, thank you for the "electric-heat.xls" calculator i stumbled upon.

so i would like to get confirmation before setting myself to disappointment.

i have obtained a keggle and i dont have access to 220 v but i have 2 GFCI kitchen circuits to run 2 elements in the kettle

According to the spreadsheet

1. step heat up mash water 7.5 gallon to 170 degree range strike water ~ 40 minutes
2. once water is in the mash prep the sparge water water 8 gallon ~43 minutes

after spargin i plan to collect 12.5 gallons of wort

3. according to calculator heating 12.5 gallons from 154 - 212 ~35 minutes

i am okay with the wait.


I am concerned that 2 1500 watt 120v elements would be enough to get 12.5 gallons to rolling boil?



Thanks,

Yev

Do you have any 120v/20 amp outlets? I run two 2000w elements and have no problems doing 10 gallon batches.

Yeah that was what I have been finding a lot .
Any recommendations on 2000 watt 120 volt ultra or low density watt elements ?

Thanks Yev

Whether 3000W is enough is dependent on kettle configuration, use of insulation (or not), ambient temperature, use of a kettle chimney, etc. There's no black and white answer. It also depends on how you define "rolling boil".

It's less than I'd recommend with 12.5 gallons but it may be enough to get at least a "reasonable" boil once you get there. It'll take you longer to get to boil however.

Good luck!

You can also use 240V elements at 120V to give you 1/4 the power output. So a 5500W element will give you 1375W.
The ultra-low-watt-density also becomes extremely low watt density since it's 1/4 the power output.
Using 240V elements also means you can re-use them if ever you upgrade to a control panel setup (240V).

Stainless base (bare) heating elements are available here: http://www.theelectricbrewery.com/stainless-steel-heating-elements
Or in kit form or assembled here: http://www.theelectricbrewery.com/heating-element-kits

Cheers,

Sort of off topic, but sort of not. I'm looking to build a HLT, but I might want to use it for different applications. How hot will a 5500w element at 240V get 15 gallons of water?
