tldr: place air inlet above the heat (B); air outlet on the other side at the floor (D). See figure: https://www.saunatimes.com/wp-content/uploads/IMG_6556-1-560... This ensures: 1) quick heat up of fresh air 2) vertically uniform heat 3) creation of better steam
I wonder if this holds true for a wood burning sauna too? An active fire in the stove creates a massive draft that'll pull air through the stove and out the chimney.
Why is the age of any relevance here?
The relevance is that someone spent 45 years, as a trained adult engineer no less, not 45 years merely breathing, aware of a problem and only after than much experience, solved it.
It would also be interesting if they had been a 1 year engineer or not an engineer at all, just for different reasons.

Is he 45, or has he been an engineer for 45 years? Either way, I wish I had this guy’s sauna.
Earlier quoted context omitted.
Because, he's FORTY FIVE! He's FRAIL with one foot LITERALLY in the GRAVE!! j/k. Someone mentioned that he has 45 years of experience. That makes him closer to 65. If he's still doing cool shit, thats pretty cool. I wish they'd explain the problem in a short sentence before diving right in. Maybe this blog is for people who already know what the issues with an electric sauna are... bad ventilation, I assume.
If you read the article, the problem is explained quite well: > In my simple mind, the Finnish Sauna is just a type of Heat Treat Furnace or Oven that you load humans into and try to provide them with three characteristics. (1) not oversaturate their lungs with their own Carbon Dioxide waste products from being enclosed in a sauna with poor ventilation and limited fresh air volume changes (called Air Mixing in the st…
I don’t see the problem defined well in the article, but it can mostly be surmised from the intro:
> Malcolm has analyzed the Finnish 1992 sauna ventilation study profile, applied his knowledge and experience as a 45 year engineer to test and better understand sauna ventilation in his own backyard sauna.
They wanted to test and understand the sauna ventilation in his backyard sauna and used a 1992 research paper as a reference. I can only assume this venture started because they were dissatisfied with the ventilation in their backyard sauna.
The sauna design rabbit hole is a very deep one. If anyone is interested in more information about sauna design in general, Trumpkin's Notes are by far the most referred to guide out there. [1] There are also new products [2] which help improve saunas which are not ideally designed or where there are constraints (ceiling height mostly) to deal with. 1: https://localmile.org/trumpkins-notes-on-building-a-sauna/ 2: htt…

Where I live, saunas have the stove’s inlet outside the sauna itself.

45 year engineer, not 45 year old engineer. It's not about their age but their experience. The relevance is that someone spent 45 years, as a trained adult engineer no less, not 45 years merely breathing, aware of a problem and only after than much experience, solved it. It would also be interesting if they had been a 1 year engineer or not an engineer at all, just for different reasons.
Am I reading this right? Is there no heat exchanger in the ventilation? That seems like an obvious improvement.
The combination of ventilation and heat source along with water poured on to the source is a way to regulate and adjust the temperature. The goal isn’t to trap as much heat as possible because having some of the heat flow out is key to regulating temperatures.
So, not really an obvious improvement at all.
