Huum Steel is a beautifully simple sauna heater that has small safety distances, so the required space is small. The Steel is easy to fit into various sauna designs and spaces. Note that a separate control unit is needed.
Depth: 320 mm
Width: 320 mm
Height: 975 mm
Weight: 15 kg
Stone capacity: 150 kg
Safety distance to inflammable materials like wood:
Steel 6: 50 mm
Steel 9: 100 mm
Steel 10,5: 100 mm
Choose the backside reflector plate when the Huum Steel is placed very close to a wooden wall or sauna bench, and then the plate will reduce the required safety distance to half. The plate is great also for protecting the backside from water splashes and the resulting coloration.
If the Steel is embedded into the lower bench, the maximum lower bench height is 425 mm. Take this into consideration in your sauna plan.
Remove the stones from the heater once per year, for inspection, replace any broken stones or stones with calcium or other deposit, and re-insert the stones carefully.
