FAQ

Is the HUUM DROP 6kW or HUUM DROP 9kW bigger?

The HUUM DROP 9kW is the larger heater at 9 kW versus 6 kW, so it suits a bigger or colder room, up to about 459.1 cf. The smaller unit is cheaper to run and plenty for a compact, well-insulated space; there is no benefit to over-sizing a small room, it just cycles off sooner.

Do the HUUM DROP 6kW and HUUM DROP 9kW need the same circuit?

No. The HUUM DROP 6kW needs a 35 A circuit (10 AWG copper) and the HUUM DROP 9kW a 50 A circuit (8 AWG), because they draw different current. Size the circuit for whichever you actually buy, and remember a long run may bump the wire up a gauge.
