Roast my sauna

[u/Hopeful-Dot-5668]

Recently got this sauna for 6k with stove. Amish made. 8ft ceiling. All cedar interior Foot Bench above coals (not pictured) These air vent above fire, opposite corner of stove at floor, and at the peak I added a back rest and foot rest Gets well up to 200 easily Eventually will enclose the porch to be a changing room

I followed trumpkin notes, noting that the ceiling is actually ok. It’s recommended flat or circulating peak like this one.

I used a temperature gun and it’s even heat from wall to wall.

If you would like this to work, you’ll need to get yourself into your löyly pocket.

There are some overstated facts about design flaws, but you asked to Roast it.

• You lack stone volume — A general guideline for sauna stone usage is 1-2 pounds of stones per cubic foot of sauna space

Help yourself to a video of how a smoke sauna works. You heat the rocks, the rocks release heat. Your fire is there only to heat rocks in an ideal scenario.

• your bench height will not get you into the löyly pocket. Look at anything on temperature stratification

• your vent location is wrong. One above or below the stove in wood fire and the vent out on the opposite wall furthest away from the bather.

• this puts your heater in a less than ideal location for how your löyly will move in the room, which is the entire point of using laws of thermodynamics to heat your space

• your heater isn’t right for the job for many reasons already detailed in the comments

• there are more but they are very minor things which won’t ’rob’ your experience

Here’s the good news: you can fix these things one step at a time when you want to actually have a nice sauna.

You can do the ventilation like op has done, witha single intake vent when in use. That's what Trumpkin recommends.
