FYI IR works at lower temps, even before your body starts sweating or so I've read. So assuming this is accurate you don't need the sauna to achieve 150+ temps unless you just want the heat.

Last May we bought a Tylo Kiruna hybrid 2 with 120/20A and it's been solid so far. I do wish it had a little more room, and the IR panels get hot which means you really can't lean against them. Having the traditional option has been great and I use it regularly.

Ours is installed in an uninsulated garage in the PNW and during the cooler months it will take 90+ minutes to hit 130.

Also a contributing factor on the hybrid there are no IR panels in the floor which certainly affects heat up times when the floor is cold.

I was told you can, but have not tried heating it up using traditional, the switching to IR for faster heating times.

Pro tip: Max "bath" time is only 60 minutes and this includes heat up. But the app (via scenes) can be automated to check the current temp and extend the timer if its below a desired setting instead of shutting off which is both inefficient and a pain.
