25 documented
Where manufacturers contradict themselves
While transcribing these 145 products we found 25 cases where a manufacturer publishes two different values for the same specification — a spec page disagreeing with its own manual, or a retailer listing disagreeing with the manufacturer. We did not pick a winner. Both values and both sources are below.
Both recorded per model as published; nominal 110/120 V wording difference, not reconciled.
One of the two published values is an error and is withheld here on purpose. Both recorded; no manual available to arbitrate. Do not publish a single occupancy figure.
Manufacturer states a 14.6 A draw alongside a 15 A outlet, without any dedicated-circuit language. No breaker size was inferred.
The other says
report tests a 600 watt 240 V infrared sauna heater / Health Mate report measurements are only of the sauna heating element and not of the sauna in its installed configuration
View sourceMarketing claims concern cabins, while both published reports test heater components. No model-level EMF value is asserted for any cabin.
Official model spec PDFs referenced on the site returned client errors this session; records rely on official product pages only.
- Dundalk LeisureCraft Canadian Timber CT Barrel Sauna — Harmony / Serenity / TranquilityKitinterior depth / volume
Recorded as published, flagged. A heater-sizing calculator fed the published 222 ft³ for Serenity would size below the 7.5 KW LeisureCraft itself recommends for that model.
- Dynamic Saunas "San Marino" 2 Person Low EMF Far Infrared Sauna (DYN-6206-01)Infrared cabintemperature and circuit wording
The other says
sauna can heat up to 140F; Non GFCI plug & play (Recommended Dedicated Outlet)
View sourceQuoted as published; Recommended Dedicated Outlet is counted as recommended, not required.
Rounding difference only; prefer manual
Rounding difference only; prefer manual
Page title is a catalogue error; use 8.0 kW
Not a contradiction but two different quantities; both recorded with their own labels.
Use manual: 10.5 kW
One of the two published values is an error and is withheld here on purpose. Treat the 1.65 in value as a page data error; do not publish it
Use manual: 11.0 kW / 8 AWG (flag: cable direction of disagreement is smaller in manual)
Use manual: 4.0 kW
Use manual: 6 AWG
Manual is the authority (8 AWG minimum); the page 6 AWG is the more conservative figure — flag for editorial review before publishing wire guidance
Use manual: 4.0 kW
- JNH Lifestyles Ensi+™ High-Heat 170°F 2-Person Far Infrared Sauna (Ultra-Low EMF)Infrared cabincircuit requirement
The other says
Our 1-2 person infrared saunas do not require any electrical modifications to your standard wall outlet.
View sourceBoth quoted; treated as the brand stating a dedicated 15 A supply while also describing it as a standard household outlet.
One source says
Redwood: Harvia KIP 6kW → "Amps: 30A"; FAQ "Two-pole 30A breaker, 10/2 wire (use 8/2 if distance >90 ft)"
View sourceElectrical-safety flag. These are different quantities (branch-circuit rating vs heater load) and must never be shown as competing "amp" values for the same model.
- Sun Home Saunas Luminar™ 5-Person Outdoor Full-Spectrum Infrared Sauna (Luminar 5)Infrared cabinpage/manual specification split
One source says
Page: Dedicated 20 Amp Circuit / NEMA L6-20 with no voltage; Luminar 5 page: Dedicated 30 Amp Circuit / NEMA L6-30, no voltage
View sourceThe other says
Manual: 240V / 4,800W / 20A; Luminar 5 manual: 240V / 7,200W / 30A, NEMA L6-30P
View sourceElectrical and dimensional data are split between pages and manuals. Manuals are preferred for voltage/wattage/GFCI language; both sources are cited. Luminar 5 exterior dimensions are printed in different axis order on page versus manual and are recorded as published.
Spec sheets are served from two different official hosts; product pages carry no specs.
- Therasage Full Spectrum Infrared Wooden Sauna, Natural Aspen Wood, 2 persons (US5951)Infrared cabinfamily-level specifications
The same wattage and heater count appear identically for the 1-person, 2-person, and 4-person models. Recorded as family-level, not model-level, and record is partial.
The other says
120V 15 Amp 60 Hz dedicated wall receptacle; Power Cord Plug Configurations: 15 amp 4945 / 20 amp 5951 & 8753
View sourceBoth recorded verbatim; nothing is resolved or inferred. This is an electrical conflict inside the preferred manual, so no single circuit value is reported for the model.
Left as NSBM. Not filled from the 60-series value.
