The Storm Series contains Four Winds Spas' 120 Volt one-pump, economical system. This series is affectionately called the "plug and play" spas and can be directly connected to any dedicated 120V service. Alternatively, the system is also convertible to 220V for higher performance.
The FW 400 is a great entry-level spa. As one of our "plug and play" models, it simply needs to be plugged into a dedicated service and it is ready to go! Be advised that the heater and pumps do not operate simultaneously in order to take advantage of the greatest economical savings.
