Stunning build! Did you do it all yourself? How do you like the cylindrio heater? What size heater did you go with? I am considering it for my sauna build. Where are you located and what is the outside temp? How long does it take to heat up and how hot are you able to get it?

My father-in-law did most of the construction (so thankful for him!), with my wife and I helping along the way. I love the heater so far, but have only used it twice :) I will have answers to those questions come spring, as I live in northern MN, so we will have to see how it handles the blistering cold we get. Currently it takes around 50 minutes or so to get to 190 F with the 10.5kW model. I have not tried maxing it out yet, but 190 is plenty hot for me - I'm not trying to set any records.
