Kettle Fabrication

[raven19]

Different schools of thought on the heat density - low is preferred to avoid any scorching. But in saying that BIAB Urns have a fairly high heat density with the elements, and I have also used Urns as kettles with no scorching issues.

The main issue seems to be that something custom made for ultra low density will cost a pretty penny!

If there is some space around the element, then surely heat convection would result in a reduced chance of scorching also.

Immersion low watt density elements are usually longer in length to spread the heat output over larger surface area.
They are quieter in their operation and in some cases last longer. Low watt density elements are more important when putting together a RIMS type systems (less chance of scorching) and a little less important when doing a full volume boil -Cheers
