Immersion heating elements

[yoboseyo]

I'm looking at getting 2 2200W heating elements. That way I can plug them into separate circuits and ensure that I get a rolling boil. Does anyone do this, and is this a good idea?

I don't want to drill a hole in my kettle. I'd rather just have portable ones that I can stick into the kettle. Perhaps mount them on the side. Is there anything like this that you recommend?

I have used one like this and it produced a good boil for a single batch: https://www.ebay.com.au/itm/Brand-N...-Hot-Water-Heater-Element-2400W-/111142275965

Do a search on "immersion element" and you'll find something suitable.

Thanks! What size batch did you boil?

Would have been about 25 litres start of boil for 21 litres in the fermenter and 19 litres finished product. Those are typical figures for a "single batch", which is configured around a 5 gallon (19 litre) keg.

If you look at all the single vessel breweries like Robobrew or Grainfather, they are designed for this batch size and only need about 2200 watts, so you might get by with a single element. Insulation around your kettle makes a big difference to the boil.
