HUUM Core 10.5kW 240V/1PH Electric Sauna Heater
The HUUM CORE lineup is a compact, stainless steel sauna heater made in Estonia and available in multiple power ratings for a wide range of sauna sizes. Its small footprint and minimal safety distances make it well suited for tight spaces and bench-integrated installations.
Options include CORE Black with a matte black casing, wood-clad versions in Alder, Aspen, or Thermo-Aspen, and the CORE ST, which ships without a casing for custom finishes such as tile, stone, glass, or wood.
In order to operate your sauna heater, you will need to purchase HUUM Core stones and HUUM UKU Control package separately. You can easily add these in by pressing + above add to cart button on this page.

HUUM electric sauna heaters get hotter than any other in North America, reaching up to 230°F. They use SGS standards, which are fully accepted in the US, allowing saunas to achieve desired temperatures effortlessly.
Other sauna heater companies are UL-listed and can't go above 194°F. This often results in lower temperatures at bench level, making it difficult to achieve the desired sauna experience.
HUUM Core will require 240V/1PH electrical line. In case you want to wire with 208V, the power output will go down by 25%. You will need a 50 Amp circuit breaker and your electrician needs to use wire size 8 AWG. You can see the wiring diagram for the system here.
This HUUM Core sauna heater is suitable for home saunas up to 460 adjusted cubic feet. Use our calculator or contact if you want to verify the size of your sauna.
We'll check your order details to ensure everything's in place for your heater setup.
You'll receive an email with an estimated lead time and any manuals you'll need.
Our support team is available for any technical questions or guidance post-delivery.
