FAQ

Is a heater included?
No. UKU only.

STU package?
STU / STUX / CORE pkgs on this shop already name UKU. Do not buy a second UKU unless our team says the carton is heater-only.

HIVE 12 / 15 / 18?
Yes — and add the UKU extension box. The main module stops at 11 kW on the US page.

Harvia Xenio on a HUUM heater?
No. UKU for HUUM, Xenio for Harvia.

Glass instead of black?
Separate listings: Glass, Mirror, Gold. Same main module class, different dial face.
