Gday all looking to build a mini HLT out of an old 19lt keg to sparge my BIAB bag with using a cheapo kettle element from big W $9. I got the inspiration off Gash Slugs You tube video on using them for a 50lt keg. Anyone had a crack at something similar to this? If it goes to plan as just a big water heater for my sparge water ill slap two of them in my 50lt keggle. How did youse find tge boil went with these cheep kettle elements? Pros and cons? Also i measured the silicon gasket hole as 38mm but saw 40mm commented any info on this? Cheers in advance for any help.
