The ZSL-310 is Harvia's 1500W, 240V heating element, and the one Harvia lists for the KIP45B sauna heater. The KIP45B uses three of them to reach its 4.5 kW rating.

Which heater it fits

Harvia's KIP45B datasheet lists the ZSL-310 as its heating element, three per heater. The KIP60B and KIP80B take different elements: the KIP60 uses the 2000W ZSL-313 and the KIP80 uses a 2670W element. If you're not sure which KIP you have, check the model on the heater before replacing the elements.

Before you replace it

Harvia recommends replacing all the heating elements on a heater at the same time, so plan on three. The KIP is hardwired; turn it off at the breaker, and have a licensed electrician do the swap.
