Default Wattage requirements

A friend introduced me to brewing and I've been doing some research and looking at building what I need. The usual back and forth in terms of what I want. But.....

Will a 1500 watt 120 volt hot water element be adequate for for a 3.5 gallon boil? I am going back on forth with starting 'standard' with 5 gallon batches and maybe going smaller with 3 gallon batches to keep the process more manageable and may try more recipes that way.

I'm assuming 5000 watts would do a 6.5 boil OK?

3700 watts will boil 7 gallons

1500W would be close, if you had some decent insulation.

If you can manage it, a 2000w element is likely a start for smallish boils, you will need a 20 amp circuit. Problem with being watt challenged is that it will take near forever to boil, and then be a weak boil at best. Of course, a big 240v, 5500w element on a controller is preferred, but a simple 2000w element will do some work. 2 elements at 2000w each is even better. 1500w will be slow and require an insulated kettle w/ marginal results.

I also have an electric turkey fryer that is only 1650 watts. It will boil 6 gallons but it takes a looong time and needs to be partially covered to maintain a boil. I guess what I'm saying is that being on the low end of wattage is not fun and adds time to your session.

To your question, 5000w will boil 10 gallons.

There is a guy here that swears he boils 5 gallon batches with 2,000W so... apparently it can be done.

Default Thanks for the input

Like I say, I'm still in the planning stage. My buddy left me with 6 gallons sitting in my basement fermenting. He knows I'm a junkie for all kinds of DIY projects. Damned him anyhow..... I met him because we both build telescopes..... I'm really resisting the urge to have another LARGE project going..... That is why I was thinking of 3 gallon batch sizes. Easier to do, but you have to do them more often. A lot will come down to what I can scrounge and put together. I'm the kind of guy that prefers to build as much as I can before I let the moths out of the wallet.

There is a guy here with a killer 3 gallon indoor no sparge electric brew rig! You need to hook up with him.

I haven't seen any 2K elements but that is barely outside the range of the
RANCO ETC-111000. If I go with 2 1.5K I could use both to get up to boil and see if one would maintain IF I went the 3 gallon route. Do you know of any comparable controllers that handle more current? This one claims a differential of 1 degree so I thought I could also use it to maintain mash temps.

If he doesn't pop in or no one remembers his handle I'll try doing some searches.

yah the Ranco or A419s are only good to 1500W.

For 2000 and up youd probably need a PID and SSR combo.

Probably can be.... but according to my math 7gal(pre-boil) would take about 40mins to bring to a boil with 2kW and 95% eff. No thanks.
To match my propane burner you need about 5.5kW... which is one of the very few reasons I have not gone electric yet. The biggest one being the place I'm renting now has no 240 hook-up available and well I'm renting so no mods.
