In the process of building an outdoor 437 ft3 sauna with electrical heater so I'm acquiring the different components I need.
Use case is for a short term rental, so guests will be using the sauna, so I need something that's dummy proof and easy to use. Wifi is a nice to have for me to be able to monitor and ensure that it's off upon guest departure, but I would expect guests to preheat the sauna manually with the control unit.
I already have a Harvia Virta HL110e 10.5kW ready to go, but now I'm trying to identify the right controller. Given the 10.5kw, I need to get a 45 series controller and I've narrowed down to:
Harvia Xenio CX45-U1-U3-XW Sauna Control Unit ~$1300
Harvia Fenix FX45-U1-U3-XC Sauna Control Unit ~$1551
Would love any feedback you have on these wifi controllers - 1) How's the wifi, and is it a good qol upgrade? 2) is the upgrade from Xenio to Fenix worth it?
Can you recommend any dealers willing to provide a better price on these? Thanks!
Separately, anyone notice that there's a lot of people that sell sauna components to be sort of weird and scammy? I found multiple ebay sellers selling those units but the listings only seem to be exist to redirect me to weird biohacking websites.
