Solid Heater That Looks Great

I’ve been using the HUUM DROP for about a month now and it’s been great. It heats up fast, holds temp well, and the app makes it super convenient to start it up before I get home. I mainly got it for the look but it performs just as well as it looks. No complaints so far.

Trumpkin Inspired Build Complete

I installed the HUUM Drop heater in a custom-built three-tier sauna inspired by Trumpkins Notes, and it’s exceeded expectations. The heater reaches up to 230°F and pairs with a mobile app, allowing me to preheat the sauna remotely which I use all the time. It integrates beautifully with the design, which includes mechanical ventilation (10 speeds), dimmable lighting, and removable benches and floor panels for easy cleaning. The HUUM Drop is not only sleek, it’s the heart of this thoughtfully designed space.

Wonderful heater and customer service

One of the main reasons why I purchased this particular heater is it saves a lot of valuable space with inside the sauna other units take up 1/3 of the leg room this doesn’t. Also looks great. Donald from radiant sactuary customer service team was highly responsive and easy to work with. I would definitely purchase from them again. For installation, you will need a licensed electrician. For controls you get the UKU Wi-Fi which will allow you to control the heater with the UKU APP. The UKU local is just a temperature setter, mounted to a wall which you also get with this package.

Instructions are clear. Installed it. Wired it up. Held my breath and flipped on the breaker, and WOW! Everything worked perfectly. Connected right to Wi-Fi. App is easy and intuitive, and the heating unit gets hot fast. I love everything about this product. Way to go HUUM!

Beyond happy with the HUUM Heater!!

This is the best decision to get this quality heater in my otherwise poorly built sauna. I’m in there every single day and absolutely ADORE THIS HEATER. It is very hot and the remote option is a dream… I set it before arriving home and jump in before bed. Highly recommend. The shipping was swift and worth every penny!!! Great customer service too! Next time I’ll get my sauna from this company as opposed to the one I chose… thank you for being on top of everything including the last minute help installing it.

These heaters are so awesome. Good customer service as well. Rare you get to talk to a real person with questions and ordering. We bought this heater to replace an old one that was on its last legs. This one gets quite a bit hotter than our old one and with the wifi set up it's so much easier to set we just do it right from our phone. Would definitely bu here again!

Worth the wait

I am only using the infrared because my traditional heater unit has still not arrived. However, I will tell you that the sauna was certainly worth the wait. It heats up very quickly within 30 minutes. It’s at 160 to 170 Fahrenheit. The shipping has taking a little long, but other than that this is as good as it gets.

HUUM is humming along

Bought this because it had good reviews and because of the looks
I have not been disappointed.
So far, it heats up fast and easily gets to 180 degrees, which is the sweet spot for us
No problems, and it looks great 

Easy to assemble
I got the Wi-Fi and it should be smoother - you have to use the main control to set up the Wi-Fi each time you turn it off, which causes some problems
Minor issue so far
All in all I am happy with this unit

Huum drop 9kw

Used for the first time yesterday, heated the sauna well, no complaints, and it looks very attractive. The directions it comes with are a disaster, and you will basically be putting it together by yourself, fortunately there are YouTube videos out there that helped greatly, otherwise I would have been completely lost. Also, the manual says you need a 50A breaker, but the module box has a sticker that says 60A, so again more confusion from Huum
