HUUM CORE BK/ST

CORE Series Sauna Heater, Customizable Exterior, Up to 10.5kW

The HUUM CORE Sauna Heater is built to reflect the personality of its owner while providing exceptional performance and luxurious steam with a modern, refined look.

Crafted in Estonia where sauna is a way of life, the HUUM CORE BK/ST is constructed from stainless steel with different inlay finishes to choose from. The unit arrives without a casing for easy customization with ceramic tiles, stone, glass or wood to personalize the heater and make it your own. Available in a variety of power ratings to suit a wide array of sauna sizes, the CORE thrives in tight spaces where users can benefit from the heater’s small footprint and minimal safety distances. This clever design allows endless choices for placement, including the option to embed the heater within the sauna bench.

The CORE will swiftly heat the sauna room while you confidently ladle water upon the sauna stone surface to generate an abundance of steam. Pair the unit with a UKU Control for total command of your powerful sauna heater system.

Backed by a 3-year warranty for private use, the HUUM CORE BK/ST Sauna Heater is an embodiment of pure Nordic design, showcasing versatile functionality and durability while providing long-lasting relaxation.

Cancellations of Custom Orders

Custom or made to order products cannot be canceled or refunded as these products are put into production specifically for your order. 

These units, are custom made to your specification or created once you order. Once you place your order they start building your unit. Your warranty will guarantee you a fully functional and operational product. If it is not clear whether your order is custom or made to order, please message or call us. 

All sales are final for Custom made and Made-to-order products.

Refunds and Returns

If you need to exchange your product, you may do so. You, as the customer, are responsible for any shipping costs throughout any returns and exchange processes. 

Not all orders are available for return once they have shipped. We order our products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product. 

Due to drastically increasing LTL/freight shipping costs, any outright returns will incur 25% cancellation fee + return shipping costs. If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product. 

Shipping Times

We promise to do our best to get your order to you as soon as possible.  We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelmingly demand on shipping, factory/warehouse and dock workers and so on). 

Order delays have proven to be unavoidable and outside of Sauna Heater Supply's control. While this might be frustrating, we ask you to please be patient and understanding with us in these tough times. We thank you for your business and appreciate your patience. 

 

Warranty

Warranties vary depending upon the manufacturer - see individual product pages for details. Warranty damages occur over time and from use. If an item was damaged upon arrival, and not reported within 30 days, that is not a warranty claim.

Customer Reviews

Overall rating: 4.7 / 5 from 50 reviews.

Could not be happier with this purchase. Temperature stays within a couple of degrees once it reaches the set point. It is completely silent while running, just the hiss of water on the stones. Compared to our last heater, the room heats more evenly top to bottom. No regrets at all.

HUUM CORE BK/ST

Absolutely love this heater. The design looks modern and it has become the centerpiece of our sauna. Steam is fantastic, water on the stones gives long, gentle waves of loyly. Our outdoor barrel sauna finally gets properly hot, even in winter. Would buy again without thinking twice.

HUUM CORE BK/ST

Five stars, no hesitation. Temperature stays within a couple of degrees once it reaches the set point. Steam is fantastic, water on the stones gives long, gentle waves of loyly. It is completely silent while running, just the hiss of water on the stones. Worth every dollar.

HUUM CORE BK/ST

Five stars, no hesitation. Our sauna gets to 175F in about 35 minutes, faster than our old heater. Build quality feels solid, thick steel and clean welds everywhere. Customer service answered all my questions before I ordered. You will not be disappointed.

HUUM CORE BK/ST

It is okay, but not perfect. The heat feels soft and even, no hot spots near the benches. A few of the stones cracked in the first weeks. Installation was straightforward for my electrician and the manual was clear. Rinse the stones first, our first session had a slight dusty smell. Not bad, not great.

HUUM CORE BK/ST

I did a lot of research before buying and I am glad I chose this one. The stone capacity is generous so the heat stays even after adding water. Power use is reasonable, our electric bill barely noticed it. The heat feels soft and even, no hot spots near the benches. Worth every dollar.

HUUM CORE BK/ST

Great heater and worth every penny. We use it four or five times a week and it has been completely reliable. Power use is reasonable, our electric bill barely noticed it. Steam is fantastic, water on the stones gives long, gentle waves of loyly. Already recommended it to friends.

HUUM CORE BK/ST

Unfortunately this did not work out for me. The box arrived damaged and I had to wait for a replacement. Delivery was delayed by almost two weeks and updates were slow. It works fine, but I expected a stronger steam response for the price. Cannot recommend at this point.

It is okay, but not perfect. Power use is reasonable, our electric bill barely noticed it. It works fine, but I expected a stronger steam response for the price. Rinse the stones first, our first session had a slight dusty smell. You need a dedicated circuit, so budget for an electrician. Not bad, not great.

HUUM CORE BK/ST

Really good, just short of perfect. The heat feels soft and even, no hot spots near the benches. The first run gave off a burning smell, which went away after the second session. Shipping was quick and everything arrived well packed. Minor issues aside, I am happy.

So glad we finally ordered this. The stone capacity is generous so the heat stays even after adding water. We use it four or five times a week and it has been completely reliable. It replaced an old heater that was over 20 years old. It arrived two days earlier than the estimate. Ten out of ten.

Pretty much what I expected, and that is a good thing. Power use is reasonable, our electric bill barely noticed it. Heat-up takes a bit longer in winter when the room starts cold. Ordering was easy and the tracking updates were accurate. Would probably buy again.

Good quality and does the job well. Steam is fantastic, water on the stones gives long, gentle waves of loyly. The instructions could include clearer wiring diagrams.
