I'm planning to install a water heater element in my boiling kettle.
I have been looking at the Reliance and Camco elements but since neither is easy to get by in Finland I really need to go for a sure bet. Unfortunately the product descriptions are not detailed enough.
In special, which size of hole would I need to make on my kettle for those?
I have an 44L aluminum kettle 40cm in diameter with walls about 6mm thick (yeah, that tick, they are for making tomato sauce).
Also, any recommendation on the wattage? Is 4500W too much for boiling about 35L of wort?
We are going to get a bigger kettle (85L) some time soon and if the experiment goes well with the 40L kettle we will install a heater on that one also (to boil about 70L I reckon).
Any preferences between the brands above?
