Thank you for this great video! I have a question though- do you account for a concrete or tile floor when calculating the adjusted volume? For example, if I am planning to build an indoor 8x8x8 sauna in my basement with wood walls and wood ceiling, but will have a concrete/tile floor, would I still factor in 64 SF of 'cold' surface in my heater sizing calculation? And if so, would I also still use this adjusted volume if I plan to have slatted wooden duckboard on top of the concrete floor? Or is adjusted volume only used when one of the walls is a cold surface? Hope to hear back so that I can order the proper sized heater for my sauna build!
Hey Tyson! The floor material does not matter at all, so we don't adjust the volume based on the floor material. The reason for this is that the heat and steam rise naturally up and even with great ventilation, the floor material doesn't matter because the heat won't be sucked into the floor. So in short, your floor is not a cold surface and does not count :)
Depends totally on the country you're in (basically which safety listing is followed), but in the US all other heaters have to be limited to 194°F per UL requirements, except HUUM which is listed as a space heater and thus can be limited to 230°F. So our heaters are 194°F or 230°F as are every other vendors in the US.
Yes! I can't be sure, but this is what I think based on my experience: 1. Since HUUM heaters can reach higher temperatures (230°, many others 195°) they need a higher cold surface adder when sizing a sauna heater as explained in the video. Why? When the temperature goes higher the cold surfaces (like glass walls that absorb and leak the heat out) demand exponentially more power from the heater. All the problems people have are with Drop heaters, that is a series of smaller sauna heaters. When you buy a smaller sauna heater for a sauna that demands more power because of these cold surfaces, the heating elements sometimes melt/break themselves when the heater is trying to push to a certain temperature but is not able to reach that since it's too small. 2. With HUUM, temperature sensor placement is different than with other brands. In the HUUM system, you place the sensor to where people sit. That is the place where you want to measure the temperature, right? In an optimal sauna environment (correctly ventilated, we have a video on how to do this), the temperature is the same across the room. However, in the US, people tend to not ventilate their sauna rooms at all, or not sufficiently. When you don't have airflow, the hot air stays on top of the sauna heater and does not move. Then the sensor shows that the temperature in the sitting area where it's measured is not as people want it to be. Then we end up in the same place as in example one, the heater pushing too hard and breaking itself. So to recap, the problems are not typically with the heater, the problems are with the sauna construction (very basics of it) and that's why the sauna will end up broken. Note! I can't know nor comment on individual cases, those are just the reasons I have encountered every time our customers had problems. By fixing them, we have been able to fix the functionality of the sauna every time and offer a better sauna experience. Note 2: We represent all the sauna brands and are not biased one way or another. Whether you want Harvia, HUUM, Saunum, or any other brand, we have it all :) Hope I answered the question, people reading, like the comment if you think it was helpful.
@@thesaunaheater thank you for your time and this well thought out response. I figured that human error was the likely cause of the issue. I personally feel that the aesthetic of Huum is superior to any other brands on the market, and as someone who likes to sauna daily the Wi-Fi capabilities make it an easier choice. I look forward to taking a trip to Finland with my family someday to experience a true sauna! Thank you!
@thesaunaheater i leave in Georgia, caucasia, i already brought 4.5 kw electric heater and i wonder if it would be good. As seller said it is recomended for 3-6 cubic meter area

Thanks for explaining, I will calculate my saunas and see how they match up.
Happy you got value from it ☺

great helpful content! do you guys ship to idaho? :)
We for sure do! We ship to every State in the US. Feel free to contact us +1 725 777-5484 or sauna@thesaunaheater.com if you need any help :)
It would be good if you added the metric equivalent on screen.
what's the max temperature your heaters will raise the sauna to?

It seems like there is a lot of disdain for Huum heaters online. As someone who has never owned one, can you explain some of this controversy?
Yes! I can't be sure, but this is what I think based on my experience:

Thank you!
My indoor sauna is 1.8 X 0. 85 X 2 m. And it has 0.7X1.9 glass door, how much kw heater do you recommend
Where do you live? In the USA? Which brand do you want? Electric or wood fired? All of these effect the sizing!

@@miqeladzemevele I strongly recommend watching this video - th-cam.com/video/Ksu1Rx9S_bc/w-d-xo.htmlsi=cpSSuDMTWqJ4d74j
@@miqeladzemevele This is a very tiny sauna, your 4.5kW will be the right size here.
