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?
We know how frustrating it is when your hot tub goes down and the part you need seems impossible to find. That's exactly what Western Tub and Pool is here for.
Here's how to get help:
Check your existing part number (found on the label inside your current control box)
Or send us a photo of your current pack along with your spa's make, model, and serial number
Email us at fixmytub@gmail.com — we'll confirm the right part and get you sorted

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?
We know how frustrating it is when your hot tub goes down and the part you need seems impossible to find. That's exactly what Western Tub and Pool is here for.
Here's how to get help:
Check your existing part number (found on the label inside your current control box)
Or send us a photo of your current pack along with your spa's make, model, and serial number
Email us at fixmytub@gmail.com — we'll confirm the right part and get you sorted
We also offer free in-home tutorials on hot tub, swim spa, and pool maintenance — so you can keep your water clear, safe, and inviting all year round.
