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 requirements240V / 30AFinnleo publishes a 240V 30 amp circuit for this model. The 4.5 kW heater computes to 18.8 amps of draw and a 25 amp minimum breaker under the 125 percent rule; the maker specifies 30 amps, one size above that minimum. Check it on the calculator.
