FAQ
Is the Harvia KIP80B or Vevor 9kW External Control (SCA-90BW) bigger?
The Vevor 9kW External Control (SCA-90BW) is the larger heater at 9 kW versus 8 kW, so it suits a bigger or colder room, up to about 459 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 Harvia KIP80B and Vevor 9kW External Control (SCA-90BW) need the same circuit?
No. The Harvia KIP80B needs a 45 A circuit (8 AWG copper) and the Vevor 9kW External Control (SCA-90BW) 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.
