Its shallow body sits almost flat against the wall, so it takes up little space in a small sauna. The solid stainless steel shell keeps the look simple. At 3.5 kW, it suits rooms from 123 to 212 cubic feet. It needs only small safety gaps between the heater and nearby benches or walls. An air duct, a passage for air inside the heater, helps the room heat up faster. The box contains the heater, wall bracket, and manual. This heater needs a HUUM UKU control to run, and the control is sold separately. You can choose your control on this page and add the sauna stones, which are also sold separately. A thermometer and a bucket and ladle are optional extras if you still need those for your sauna. Prefer a ribbed shell in the same size? See the [HUUM CLIFF Mini 4 wall mounted heater](https://norsesteam.com/product/huum-cliff-mini-4-mini-series-3-5kw-sauna-heater/). The HUUM STEEL Mini 4 ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee. ### Elegant Heaters in the Heart of Your Sauna Pure Nordic design of HUUM sauna heaters enhances the natural beauty of sauna stones and brings the sauna interior to life.
