Searched the forums but found varying conclusions. I would like to do 4 gallon boils. I have two 750 watt traditional hot plates but even together they only simmer 4 gallons of water. Good for sparge water but not boiling.

I see 1800 watt induction 110 volt hot plates.

Any experience with the induction hot plates?

How much wort can be boiled with this type of hot plate?

I've used a 1500W unit to boil 3 gal. Takes about 40 min from room temp. Less if you start at mashout temps.

Thank you for sharing your experience. Sounds 4 gallons wouldn't be a stretch if I wasn't in a hurry.

see here for a similar setup, and my post at the end on efficiency
http://www.homebrewtalk.com/f11/indu...frared-282175/

basically at full power, an 1800w induction buner is good for around 3500BTU/hr. that is similar to the output of a 1000w immersion element. that is enough power to maintain a boil, it just might take some time to get there with 4 gallons.

I love my induction hot plates. I generally do 3 gallon brews so my wort is about 4 gallons. You can use them anywhere without danger of fire.

The cheapest setup which works very well is - 1800w plates ( the largest you can use at 120V) which I found on Amazon for $66 each and graniteware 34 quart stock pots which have magnetic steel. I insulated these by wrapping each pot with folded over bath towels tied with belt. One of the great things is that they can't burn with induction. I put ball valves on them for convenience. Mash tun has mesh filter.

Procedure;

Put mash tun on burner and heat to strike temperature. Takes a little while.
At strike temperature dump grain. Set induction plate to very low to keep mash temp constant.
Meanwhile, in wort boil kettle heat water to sparge temperature
BAtch sparge in usual way.

Transfer wort to boil kettle set induction plate to highest temp. Wort boils pretty quickly because wort from mash tun is quite hot. lower temp setting to low prevent boil over.

I routinely boil up to 6.5 gallons of wort on my commercial 1800w induction burner. After sparging and collecting all of my already 160 degree ish wort it takes me 30-40 to reach a low rolling boil. I use a cheap polarware pot that just by chance actually worked with my induction burner.

I really like using induction and am planning on getting a 240v 3600w burner to try and do ten gallon batches with.

What brands/models of burners are you all using? I see a Max Burton 1800W for under $70, anyone use this one?
