Electric sauna heaters

Every model here was transcribed from the manufacturer’s own manual or spec sheet. Where a manufacturer publishes a breaker size or a wire gauge, we quote it. Where they do not, the field says so — we never work one out from the other.

Where a card shows retailer names, those are affiliate links — we may earn a commission if you buy, at no extra cost to you. Cards marked “Direct from vendor” earn us nothing and are listed on identical terms. Nothing on this page is ordered, filtered, or worded differently because of it. Full disclosure.

What we left out, and why

A directory is only as honest as the things it admits it excluded. These 10 were considered and left out:

  • Harvia KIP45W-3ph (JH45WU3UL), KIP60W-3ph (JH60WU3UL), KIP80W-3ph (JH80WU3IUL)208 V / 3-phase only — not a residential 240 V single-phase configuration
  • Harvia Virta HL110 208 V (HL11U3UL)208 V / 3-phase only
  • Harvia Cilindro HPCS8U3H / HPCS11U3H (manual entries)208 V / 3-phase only
  • Harvia Legend US models (HPOE704, HPOE1104, HPO1104XE/XW/FC, HPO704FC, HPO165400)The only Harvia-hosted Legend manual found is the EU edition: electrical data is given as mm² and European fuse amperage, with no US 240 V table. No US amperage/wire can be established without inference.Source
  • Harvia SpiritProduct page is a marketing page; no per-model electrical table located on Harvia in this sessionSource
  • Finnleo Magma 21.0 / 24.03-phase 208 V / 480 V only per Magma manual — commercial, no residential 240 V 1-phase configurationSource
