I have a plastic HLT Rather I HAD a plastic HLT. The element was no longer submerged, I was happy in a sparging world of my own and the element became a bit hot and melted the plastic HLT. I have another, identical plastic bin I could use but am wondering if I should go stainless steel. I only do 23l batches so don't need a massive HLT. I had that HLT over 12 years.
