- Strong Spas (multiple models)
- Evolution Spas (Costco Evolution series)
- Emerald Spa
- Great Lakes Spas
- QCA Spas
- FreeFlow Spas (Watkins)

- Various other OEM spa brands using Balboa VS-series control systems
Not on this list? Many additional hot tub manufacturers use Balboa control systems under their own part numbers. If you know your part number, make, model, or serial number, contact us and we'll confirm compatibility before you order.
Frequently Asked Questions
How do I know if the VS300 is the right replacement for my spa?
The best way to confirm compatibility is to check the part number on your existing control box or circuit board. You can also send us your hot tub's make, model, and serial number and our team will verify the correct replacement for you. Email a photo of your current system to fixmytub@gmail.com and we'll get back to you promptly.
Does this system come with a topside control panel?
Some VS300 configurations include a panel; others are sold as the pack only. The specific topside included (or required) can vary by model number. Call us at 1-855-248-0777 or check our online catalogue to confirm what's included with your specific unit.
What's the difference between the VS300 variants (54626, 303030, 55506, etc.)?
Different part numbers reflect different factory configurations — including voltage setups, ozone connector type, and AV connector options. The core system is the same Balboa VS300 platform. If you're unsure which variant you need, send us your current part number or a photo of your existing pack and we'll identify the right one.
Can I run this system on 120V?
Yes, the VS300 supports both 120V and 240V operation. However, note that heater output at 120V is approximately 25% of the rated 4.0 kW (roughly 1.0 kW), which significantly reduces heating performance. 240V operation is strongly recommended for optimal heating.
My part is hard to find — can Western Tub and Pool help?
Absolutely. Hard-to-find parts are our specialty. Send us an email at fixmytub@gmail.com with your part number (if known), the make and model of your hot tub, serial number, and photos of the part or system. Our team will work to track down the right component for you.

Western Tub and Pool offers free in-home tutorials covering hot tub maintenance and operation. We're also available by phone and email to walk you through the basics. Call 1-855-248-0777 to speak with our team directly.

Frequently Asked Questions
How do I know if the VS513Z is the right replacement for my spa?
The best way to confirm compatibility is to check your existing control box's part number, typically printed on a label inside the enclosure. If you can't locate it, send us your spa's make, model, and serial number—or a photo of your current pack—and we'll help you identify the right part. Reach us at fixmytub@gmail.com.
What's the difference between the VS513Z and other VS-series systems?
The VS513Z is configured specifically for a 2-pump setup with an optional circ pump, a 2-speed Pump 1, and a 5.5kW remote heater. Other VS-series models (like the VS501SZ or VS520SZ) differ in pump configuration, amperage, and heater rating. If you're unsure which model you need, we're happy to help.
Can this system run on 120V?
The VS513Z is primarily a 240V system, but circuits are convertible to 120V. At 120V, the heater output drops to approximately 25% of its rated 5.5kW capacity (roughly 1.375kW). For most full-size hot tubs, 240V operation is strongly recommended.
Is installation included or is this a DIY part?
The VS513Z comes with a detailed owner's manual and wiring diagram to support installation. If you're not confident with electrical work, we recommend hiring a licensed electrician or spa technician. Western Tub and Pool also offers guidance — call us at 1-855-248-0777 and we'll walk you through what you need.
What warranty comes with the VS513Z?
The Balboa VS513Z includes a 2-year manufacturer's limited warranty. Contact us if you experience any issues and we'll help you navigate the warranty process.
Is this part hard to find?
It can be. The VS513Z is an older but widely used system, and sourcing it through the right supplier matters. Western Tub and Pool specializes in hard-to-find spa parts — if it's not in our current stock, we'll do our best to track it down for you.
Can't Find the Right Part?

Frequently Asked Questions
How do I know if the VS501Z is compatible with my hot tub?
The best way to confirm compatibility is to check the part number printed on your existing control board, or to send us your hot tub's make, model, and serial number. You can also email a photo of your current spa pak to fixmytub@gmail.com and our team will identify the correct replacement for you.
What voltage does the VS501Z operate on?
The VS501Z is a convertible system that operates at either 120V or 240V, making it suitable for most standard residential hot tub electrical configurations.
Does this system come with a heater?
Yes. The VS501Z includes a 4.0kW heater with two integrated sensors, so you won't need to purchase or install separate temperature or high-limit sensors.
Does the VS501Z come with a topside control panel?
This depends on the specific kit. Some configurations include a VL401 topside panel and overlay; others are sold as the control box only. Contact us at 1-855-248-0777 and we'll make sure you get the complete kit you need.
Is the VS501Z still in production?
Balboa has discontinued the VS501Z and is transitioning to the newer BP5 series (e.g., 50-BP5-500-55-K). We still carry VS501Z units while stock lasts. If the VS501Z is no longer available, we can help you source a compatible BP5 replacement.
