Electric heater HUUM STEEL 3.5kW is a narrow-shaped compact wall-mounted heater made in Estonia from high-quality stainless steel. It has been developed with small (3.5-6 m³) home saunas in mind and saving space.

Its safety distances from the walls are only 5 cm, and these excellent figures are achieved by a carefully thought-out design and the introduction of an air tunnel. In the center of the HUUM STEEL 3.5kW electric heater, there is an evening tunnel, which on the one hand ensures effective air flow and accelerates heating by approximately 25%, and on the other hand extends the life of the heating elements.

The HUUM STEEL 3.5kW electric heater is small in size, but it can hold 60 kilograms of stones, which ensures long-lasting and pleasant steam.

The set includes an electric heater.

Heater also needs a control panel, 60 kilograms of stones with a diameter of 3-5 cm and a heat-resistant power cable.


We recommend using round stones in the heater because they provide milder steam. Thanks to the rounded shape of the heater stones, the water moves between the stone layers and can evaporate gradually, instead of evaporating from the top layer all at once.
