Sauna Heater Recommendations

I currently have a huum drop that’s giving me issues multiple times and I’m just tired of it. I don’t wanna have to keep replacing the elements. Before anybody recommends installing the heat shield that huum provides I did that, and it completely melted that it did nothing. I’m looking at getting a 10kw harvia cilindro pc as I no longer want a wifi option because I want to always be home when running my sauna for obvious reasons. I want something more powerful than the 6kw drop which would take 1.5 hours to get hot. Any thoughts on the cilindro? Or any other models for that matter.
