I've acquired a 50L keg that I'm going to use as a boil kettle but I just have a few queries that yous might be able to answer. First off, it takes long enough to get 25L of wort up to a rolling boil on the burner that I have so I was thinking of putting a heating element in the keg. Does anyone know of a good element to use? Would I need to get two for that amount of wort? Can you get an element with a power adjuster on it? And finally, how expensive on the electricity are they to use?
If anyone can give me some answers or guidance is really appreciate it.
Cheers
Re the cost, it depends on your elements. If you have a 2.2kw element then the electricity usage is 2.2 units per hour. Airtricity is something like 20c / kwh at the minute, so 20c x 2.2 = 44c per hour. Then it depends on how long it's on for (Strike and Sparge water, boil etc).
I think that's how it works.
