FAQ
Is the Harvia KIP60W or Harvia KIP80B bigger?
The Harvia KIP80B is the larger heater at 8 kW versus 6 kW, so it suits a bigger or colder room, up to about 424 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 KIP60W and Harvia KIP80B need the same circuit?
No. The Harvia KIP60W needs a 35 A circuit (10 AWG copper) and the Harvia KIP80B a 45 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.
