Cadco LKR-220 Countertop Heavy Duty Cast Iron 220-Volt Hot Plate, Stainless Steel, For Commercial Use,18 lbs

I had some concerns when I ordered the unit but it worked great. It says for "up to 15 quarts" but It worked fine with my 21 quart pressure canner. I'd also read that it takes a long time to cool down (which it does) and was concerned that temperature control would be a problem. But that wasn't an issue either. I dialed it down significantly at first once it reached the desired temperature and gradually turned it up to med/high. Careful monitoring and adjustments during the processing yielded great results.

This works great to bring large quantities of liquid to a boil. I will boil 7 to 8 gallons at a time. It will take almost an hour to get to the boil but Ian in no hurry.

I wanted a large and high wattage heating element to use for canning. I do not like using my glass top stove for that. This was just what I needed, except for one huge problem: it needs a 220 outlet! We can use the one in our basement, but will have an electrician put one in the kitchen. So, for anyone needing a higher voltage and larger heating element, this one is really nice, not flimsy like most smaller ones!

Came in a broken box, with a 1/2 stripped cord and a dent. :(

takes forever to heat up; more than an hour to bring 3gal of water to a weak boil and about 15 minutes to get a cast iron skillet hot enough to cook an egg.

Works great with heavy bottom pots. Boils 4 gallons room temp water in about an hour at 800ft above sea level.

I purchased this for canning because I have a glass top stove. It surpassed my expectations!

Haven't used yet, but looks like it will work well.
