ust checked the first dozen immersion heater elements on Screwfix and

Maybe higher wattage ones do exist but Ive never come across one.

Industrial vs domestic.


Well the OP didnt hint in any way that this was an industrial unit so I
think its unlikely to be more than 3kW.

It's on its own 20amp MCB according to the photo.


Lets not forget that the OP also stated €œ The heater itself is 3kw and the
circuit is 20A €œ.


Now he *could* be mistaken, but what readily available immersion heater
element could run from a 20A mcb? Are 4.8kW elements common?
