Is it possible to do full boils without a propane burner?

I have done several full boils on my cheap Whirlpool electric range. It takes a long time and is a bit of a pain but it's possible. I stopped when the burner overheated and the plastic harness that connected the heating element to the wires melted and/or burnt to ash.

So in summary, it probably depends on the quality and capabilities of your stove. My advice is to try it with a smaller batch to see how it handles it, then work your way up as you feel comfortable with your equipment.

Boiling 6 gallons on a 3.5 kW induction top works flawlessly.

I've gotten a pretty solid rolling boil on a single burner with my 7 gallon pot. That said, my rental has a pretty fancy stove.

The advantage you get from the propane burner is a harder boil. You brew on any stove that can boil water (my wort usually starts boiling at about 215F, almost water's boiling temp). However, if you have a lower temperature, make sure you start you hop additions only after you have a full boil, you don't want to miss the hot break or not boil off the dms.

You can even brew inside on a plain gas stove, depending on your pot. When I lived in overseas and didn't have my propane gear, I used the stock-standard gas stove/oven with four small burners like you see in many houses in the USA. (Older houses, that is, not newer ones with big stove-tops and wide-spaced burners.) My pot, which was about the same size as yours, straddled two of the burners.

I used an aluminum pot specifically because its heat distribution and transfer are better than stainless steel, and with just the two small stove burners, I did full 6+ gallon boils, boiling down to 5 gallons. But you have to make sure you use a pot wide enough to straddle the burners; tall, narrow ones won't cut it.

Another consideration if you do that, though: Humidity control. There was a LOT of moisture coming off of there. In one place I fortunately had a window right there at the stove, and I rigged a small attic exhaust fan on a piece of plywood that fit right into the double-hung window. That was enough to really get the steam out. Typical stove hoods didn't pull enough air.

I have gotten full boils on my (gas) kitchen stove. I do have to straddle my kettle over two burners, but the kettle is so large that it fits over two burners.

I would look into a heat stick (that's one of the original writeups, but there are plenty of new ones now, too). It might be just enough to supplement your burners.
