HIVE Heat is a highly efficient wood-fired sauna stove for smaller saunas.  Its unique structure draws fresh air into the burning process from above to create a stronger flame, which results in a cleaner, more complete burn. The sturdy furnace door is made of cast iron, which is both durable and easy to maintain. This floor-mounted stove holds up to 198 lb (90 kg) of stones, which ensure a long-lasting hot steam even for larger groups, without compromising on design.

Water Exchanger

Superior Sauna Sauna HUUM Water Heat Exchanger

A water exchanger heats water when the sauna is heated.  The water exchanger is made of 0.2 in / 4 mm steel and coated with heat-resistant paint, has ¾″ male pipes for connecting the water exchanger to a water tank, and may be placed on the rear edge or on the sides.

Heater Stones

Superior Sauna Sauna Round Stones

We highly recommend using rounded stones in HUUM heaters to complement the design and have milder steam. In our selection, we have rounded olivine diabase stones: 5-10 cm. The stones are durable and have high heat capacity. You can also use other types of stones in HUUM heaters, except decorative stones because they can break easily.

Protective Bed

Superior Sauna Sauna Hive Safety Rail

The HUUM wood protective bed, protects combustible materials from the heat of the wood-fired sauna heater. (Not designed for the heater with extension)

HIVE Reflector

Wood Stone Cage

Superior Sauna Sauna Hive Wood Stone Cage

The stone cage is mounted straight on the stove around the flue and filled with sauna stones. Thanks to the added stones, the surface for pouring water significantly increases, and that means less hot metal surfaces, that we wish to keep minimal in the sauna.  The stone cage filled with sauna stones is also a decorative element, matching with the sauna heater. Stone cages can be installed on top of each other.
