Time to upgrade your old spa pack hot tub heater?

Balboa VS501z, uses simply the best spa pack technology in the market. Completely digital circuitry means less failures, more accurate heating range, and much simpler to use. Accurate to +/- 1 degree with full top side LCD controllers, means, you will never have to leave the spas or tub to change the temperature.

TheVL 401 LCD controller is more costly than the LED style VL403 controllers however it provides much better lumination durring the day. As such all our Spa Pack come standard with the upgrade to LCD controller.

The Balboa Spas Pack works at either 120 VAC producing 1.5KW, or with a change of a jumper operates at 230 VAC producing 5.5 KW of heat. It fits any standard 2" or 1 1/2" plumbing making it ideal to upgrade almost any older mechanical spa pack.

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 Sas, 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
  • 4 button LCD light duplex digital control VL401with 7' cable
  • One 4-wire 2-speed pump cable with AMP plug
  • One 3-wire pump/blower cable with AMP plug
  • One 12 volt light wiring assembly with AMP plug
  • One loose 4-pin AMP plug with pins ( to adapt a non-Balboa ozonator)
  • 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, after the pump or before or after the filter).

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.

The LCD digital topside control includes light function, high low pump, temp control, and blower. Functions may be changed to Temp Up, Temp Down, Jets, and Light. The unit is backed by a 2 years manufacturer warranty that includes the heating element.
