Step 3 of 3 Additional options

Include heater flange?

The embedding flange is useful when you are planning to install your sauna stove partly inside the sauna bench. It's made of stainless steel and it covers up the wooden edges around the stove, leaving the final result looking refined and smooth.

Include a reflect?

Thanks to the placement of the reflector on the heater it is possible to achieve half smaller safety distances from the walls. It is made of stainless steel and is mounted on the side of the heater. The reflectors can be connected to each other.

The Steel is designed to shine in smaller saunas, with a slim design and minimal safety distance requirements. And with an even slimmer 3.5 kW mini option that’s narrower than the full-size Steel heater, the Steel is a compact sauna’s best friend.

But don’t mistake compact sizes for less power: Huum heaters are engineered to pack a punch with incredibly high stone capacity and direct contact between the stones and the heating elements. The naturally high thermal mass of stone slowly releases heat, meaning fewer fluctuations in the temperature of your sauna.

And that’s just one benefit – the rounded shape of the sauna stones makes for greater surface area and more airflow through the heater, meaning your sauna will heat faster and more efficiently. Also read as: less wait time and more efficient (and affordable!) operating

Huum heaters are designed, manufactured, and tested in Estonia, a small coastal country next to the Baltic Sea. Estonia has a rich sauna heritage dating back to pre-recorded history. Every element of Huum heaters from the materials to aesthetics to experience is crafted to be of the highest quality.

We sell Huum heaters as kits instead of individual parts and pieces to take the guesswork out of building your dream sauna. Everything you need from the correct number of stones to the remote controller are all included, along with optional accessories to tailor it to your space.
