Description
Tuck your heater out of sight with the Huum Core 6.5kW electric sauna heater, made for sauna rooms of 177 to 318 cubic feet. The compact CORE can be embedded completely into a sauna bench, and it comes in a choice of finishes: a black metal exterior, or alder, aspen or thermo-aspen wood panels with a stainless steel or black inlay.
It is sold as the heater only, which makes it a simple swap if you already have a HUUM UKU control and stones. It runs from a HUUM UKU control (UKU Local, UKU 4.2 Wi-Fi or UKU Glass, sold separately), and you can add a control and the two boxes of small sauna stones it needs (33 lbs each) on this page. Designed and engineered in Estonia.
