Warranty
what this meansThe warranty term the manufacturer publishes, in years. Some makers instead warrant the sauna structure for the life of the original owner, which this column shows as "Limited lifetime"; that is a different promise from a fixed number of years and covers the shell rather than the heater, so the two are not ranked against each other.

Exterior dimensions
what this meansThree figures as the manufacturer publishes them. The source does not name which is width, depth or height, so this site does not label them either.

Power requirementsHarvia Vega Compact 1900 traditional heater: 120V, 1.9 kW, 20 amps; infrared panels: 120V, 1750 watts, 15 amps, NEMA 5-15PThe maker publishes two circuits for this combination cabin: the Harvia Vega Compact 1900 steam heater at 120 volts, 1.9 kW, 20 amps, and the infrared panels at 120 volts, 1,750 watts, 15 amps on a NEMA 5-15P plug. The 125 percent continuous load rule puts the minimum for each circuit at 20 amps, so the infrared side's marked 15 amp plug sits below that calculation. NEC 422 gives the rating marked on a listed appliance authority over the calculation; confirm both runs with your electrician. Check it on the calculator.
