Warranty: every panel

The warranty term on every panel, and who stands behind it.

Warranty terms are 2 years across the 6 panels. 3 carry no clean term, so the manufacturer's own wording is shown instead of a number.

How these are worked out

The term comes from the record. What a term actually covers is a brand promise rather than a product one, and it is rarely one number: a cabinet, a heater, controls and glass are usually covered for different lengths of time. Each brand page carries that full table with the date it was captured, so the brand here is a link to it rather than a summary of it.

Assumptions: electricity at $0.17 per kWh (US average), cost per session over 3 years at about 1 session per week (price divided by 156), sauna running cost at a 30-minute session. These are estimates for comparison, not quotes.

How we vet

What owning panels involves
OwnershipWhat it means
UpkeepA dry microfiber wipe over the diodes with the device unplugged, and airflow kept clear: the panel is not run pressed against soft furniture, and the fan intake is kept free of lint. Cords, housing and hinges get a longer look about once a week.
What you rebuyNothing
Service lifeDiodes are rated around 50,000 hours, which Mito Red states for its own panels under a 2 year warranty. The sources are explicit that the diodes are usually not what fails first: dust, blocked airflow, hot storage and cord stress are what end a panel. No source states a percentage of output lost per year, so none is given here.
Where they failFans clogged with lint, and heat trapped by running the panel against a soft surface; Power cords and plugs, stressed by being pulled at an angle; Internal switches, batteries and housing, which the sources put ahead of the diodes

These apply to the class, not to this record alone, and they are sourced from the manufacturer guidance for it. Anything a source does not state is left out rather than estimated.
