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
  • Polar Sauna HMR 45 / 60 / 80 / 86 (+3-phase variants)polarsauna.com returned HTTP client errors (403-class) for every per-model page on 2026-08-21; no manufacturer data could be read. Not excluded on merits — retry needed
  • Scandia Ultra Medium 6.0 kWscandiamfg.com page returned an IP-block error on fetch
  • Helo US, Amerec, Narvi, Tylö Bliss/Combi, EOS, Sawo, Mr. SteamNot fetched in this session (time budget); see gaps
  • Harvia Forte AF100 (HAFU1002401)Kept as partial rather than excluded — manual data exists, product page 404
