5 kW Sauna Heaters

5kW sauna heaters are suitable for smaller saunas, usually ranging in size from about 4 to 8 cubic meters or 140 to 280 cubic feet. The exact size recommendations vary based on the chosen model. So in short, 2-3 person saunas can usually operate with a 5kW sauna heater.

There are multiple options available when it comes to 5kW sauna heaters. The most popular manufacturers in this category are Harvia and HUUM, which are known to be the leading sauna heater brands as of writing this.

From wall-mounted models, the Harvia KIP is an all-time best seller world wide, thanks to its incredible price/quality ratio. If you’re looking for more advanced technology and award winning design, then take a look at HUUM Drop 4.5kW.

Free-standing sauna heaters are usually for bigger saunas, so there’s not any available with 5kW. However, the 6kW HUUM Hive Mini is worth looking into, in case you have a slightly bigger 3-4 person sauna.

A good rule of thumb with sauna heaters, is that if you’re considering between two sizes, it’s better to take the bigger one. For example, a 250 cubic feet sauna can use either a 4kW sauna heater or a 5kW sauna heater, but it’s better to go with 5kW. Consistently operating a sauna heater at its maximum capacity can lead to more wear and tear, rather than it breaking more easily. It’s rare to go oversized, but typical to go undersized, when it comes to sauna heater selection.
