Replaces any Spa Pack from other manufactures!

Don't be fooled, Balboa Spa Packs can replace any hot tub heater on the market including Gecko, Hot Springs, Len Gordon, Hydro Quip, LA Spas, Cal Spas, Coleman Spas, Beachcomber Spas, Artic Spas to name a few......

Built in programmable features such a cycle programming, sleep mode, economy mode and self diagnosis are just some of its features. Weather freeze ups are eliminated with the built-in freeze protection system. It also has the ability to select how much current will be drawn allowing use of a 30 Amp breaker or 40 Amp, yet still deliver the full features.

It has receptacles for the following:

One 2-speed pump + one 1-speed pump or blower (not both) + one circulation pump + one ozonator + one constant-on for Audio/Visual devices + one 12 volt light. All receptacles (except light) can be switched to supply 120 Volts or 230 Volts.

Comes complete with:

VS501Z pack including Stainless Steel portable heater with 2" heater tail pieces

Plasticized control instruction sheet; complete instruction manual for retrofit situations produced by Northern Lights

The Patented M7 Technology removes the need for pressure sensors and remote heat sensors common on other older spa packs. This unique technology allows the spa pack to be positioned in any location or direction (before or after the pump, or before or after the filter). Unlike other hot tub heaters, the flow direction does not matter.

What is the difference between a regular VS501 and VS 501Z?

Only the VS501(Z) is able to run either 220 VAC or 120 VAC accessories or a mixed combination! The latter & older models require accessories such as ozone to be the same voltage as the primary pump, limiting their applications. The VS501z is the most current model line from Balboa.
