Vian Power Spa Pack Review (2026): Is It Still Worth Buying?

Last updated: September 2026

Vian Power spa pack, what’s that all about? Vian is a name you probably associate with hot tub chemicals. They’ve been around a long time, and I use their products myself. So when they brought out a complete spa pack with a topside control, I wanted to know why we should take notice. There’s no shortage of spa packs and topsides on the market, after all.

In this review I’ll look at what the Vian Power spa pack actually is, the specifications, who it suits, and whether it’s still worth buying in 2026.

What is the Vian Power spa pack?

At first glance, the bold styling looks pretty cool and very current. The purple logo stands out perfectly against the black plastic case. Then you look closer and think, hold on, I’m sure I’ve seen this somewhere before. How could I, when it had only just been released?

Look at the body again and you’ll spot the familiar logo: powered by Balboa. The penny drops. This is a Balboa BP-series system made for Vian under an OEM deal. One of the most trusted names in our industry is simply selling a pack under a different brand.

How do we know it’s a Balboa BP in disguise?

This one’s easy. Look at the topside control below. Does it look familiar? Of course it does. It’s a Balboa TP600 with a Vian bezel and overlay.

So is it just a BP601 under a different name? Not quite. Balboa’s BP601 tech sheet shows it runs two pumps at most, while the Vian runs up to three. In fact, the Vian’s 18-setup output table (below) is identical to the one in Balboa’s BP8 tech sheet. So think of it as a larger BP-series pack, not a BP601.

Vian Power spa pack specifications

The 18 output setups

The pack is configured for your equipment by choosing a setup. This is the bit people get wrong most often, so it’s worth a proper look. There’s a walkthrough in Configuring a Balboa spa pack.

16A or 32A supply?

Like other Balboa BP packs sold in the UK and Europe, this one can be set up for a 16A or a 32A single-phase supply. Balboa’s BP tech sheets explain that on a 16A supply the pack limits what can run at once, so the heater switches off while high-speed pumps run. On 32A, the heater and jets can run together. If you’re building from scratch, I’d put in a 32A supply. It makes for a much nicer soak in winter. Either way, the supply needs to be done by a qualified electrician. See Hot tub wiring explained and A guide to hot tub electrics.

What is M8 heating technology?

Balboa pitched M8 as a big step forward for water heating. It’s software built into the BP control system that tries to reduce how often the pump runs just to check the temperature.

Here’s how it works. A BP system checks the water temperature by switching on the pump and running water through the heater, where its temperature sensors sit. Each check is called a “poll”. According to Balboa’s M8 information guide, M8 polls every 30, 60, 90 or 120 minutes, and those intervals are called M8 cycle times. When the water temperature stays stable, M8 stretches the interval. At the full 120 minutes, that’s 12 polls a day instead of 48 at 30 minutes. Less pump running means less electricity and less wear on the pump.

Two things to know:

• M8 only works in Ready mode, not Rest mode. If you’re not sure what those mean, read Balboa heat modes explained.
• It resets to 30 minutes if the temperature drops or you press a button on the panel, because the system assumes you’re using the tub.

It isn’t magic. You won’t notice it day to day. But it’s a sensible bit of software, and it’s in the Vian Power because it’s a BP system underneath.

Vian Power model numbers

The main kit is PK-VP610. It comes with everything, including overlays for the topside so you can label the setup you’ve configured. PK-VP609 is the same kit without overlays, which suits a hot tub engineer who carries overlays separately and picks the one they need. There’s very little difference in price, so I’d go for PK-VP610.

At launch there were also configuration-specific part numbers: PK-VP611 (single pump, no blower), PK-VP612 (single pump and blower), PK-VP613 (two pumps and blower) and PK-VP615 (three pumps, circulation pump and blower). The TP600 overlays were OL-60050 (single pump only), OL-60051 (single pump with AUX), OL-60052 (two pumps and AUX) and OL-60053 (three pumps and AUX). In 2026 the UK stockists I checked list PK-VP610 and PK-VP609, so ask before you rely on the others.

Is the Vian Power still available in 2026?

Yes, in the UK at least. As I write this, parts4tubs.co.uk has the PK-VP610 retrofit kit in stock, and other UK retailers such as Hot Tub Parts list the 3kW and TP600 bundle at a similar price, roughly £780–£830 including VAT at the time of writing. Prices move, so check on the day.

For US readers: I can’t find the Vian Power sold in the USA. It’s a 230V 50Hz European product. In the USA, look at Balboa’s 60Hz BP range instead. How to select a replacement spa pack walks you through choosing one.

Vian Power vs Balboa BP8

The obvious alternative is Balboa’s newer BP8, which I’ve reviewed in Balboa BP8 review. It has the same 18-setup output table, and it’s designed to replace most BP and GS packs. Here’s how they compare:

	Vian Power	Balboa BP8
Made by	Balboa (Vian brand)	Balboa
Heater	3kW	3kW
Outputs	Up to 3 pumps + circ + blower, 18 setups	Up to 3 pumps + circ + blower, 18 setups
Topside	TP600 in the box	Bought separately or bundled. Works with spaTouch 2 and 3, TP200 to TP900 (firmware dependent)
Heat pump control	Not something I can confirm	Controls a Balboa Clim8zone heat pump directly (with the right panel firmware)
Best for	A complete, simple kit with the topside and plugs in one box	Replacing an existing BP or GS pack, or pairing with a Clim8zone

My honest take: if you want everything in one box with a TP600 and you’re not planning a Balboa heat pump, the Vian Power is still a good kit. If you’re planning a Clim8zone, the BP8 is the better fit. If you’ve got a different heat pump, it can still be run from almost any pack. See How to control a heat pump with any hot tub spa pack.

Can you add WiFi to the Vian Power?

Balboa BP packs take a WiFi module. Balboa has two apps, and they work differently:

• Spa Control – BWA works with the older bwa WiFi module (part 50350). It now has paid “cloud mode” subscriptions ($2.49 a month or $24.99 a year on the App Store) if you want to control the tub away from home. European retailers such as tubs.parts report the same change, at around €25 a year. On your home WiFi (local mode), it’s still free.
• ControlMySpa uses a different gateway module. The ControlMySpa app currently lists no in-app purchases or subscription.

The Vian Power isn’t named on the module compatibility lists I found, so check with the supplier before buying. There’s more on the ControlMySpa module, including what it does well and what it doesn’t, in my ControlMySpa review. You can get the ControlMySpa WiFi module from my shop.

Who should use the Vian Power spa pack?

It’s marketed at hot tub technicians, because it comes with everything needed to get a customer’s broken tub running again in one visit. But for me, as a hot tub designer and builder, it’s a great package too. It comes with a topside controller and the AMP plugs in the box, and it covers everything from one pump to three.

No more mixing and matching topsides, or checking whether a pack can run a couple of pumps or needs an expander board. Wholesalers have bundled packs for years, of course. What this does is give you every option in one box.

It’s a good fit if you are:

• Building a DIY tub in the UK or Europe and want a proven Balboa pack with a matching topside.
• Replacing a failed BP-series pack and want a like-for-like complete kit. Check first whether you just need a board. See Replace spa pack or just the circuit board? and How to identify a Balboa circuit board.
• A technician who wants one kit in the van that covers most jobs.

Common mistakes and troubleshooting

• Wrong setup selected. If a pump won’t come on or the blower button does nothing, the setup probably doesn’t match your equipment. Check it against the table above.
• Wrong overlay. The buttons do what the setup says, not what the sticker says. Match the overlay to the setup.
• Heater never runs with the jets on. That’s normal on a 16A setup. It’s the pack protecting the supply, not a fault.
• Breaker or RCD tripping. Usually a pump, heater element or wet connection, not the pack itself. Work through my breaker tripping guide.
• Not heating. Check flow first (filters, airlocks, circ pump). See Help! My hot tub is not heating.
• Getting the plugs wrong. Use the wiring diagram inside the lid. Demystifying spa pack wiring diagrams shows you how to read it.

My verdict

There’s no denying this is a Balboa BP pack with a clever bundle around it: a rebranded TP600 topside and all the plugs in the box. I love the styling. That’s the inner designer in me. It just looks cool (which I’m told nobody says any more).

In 2026 it’s still a solid, well-proven choice for UK and European builds, and I’d happily fit one. Just compare it with the BP8 first, especially if a Balboa heat pump is on your list, and think about which WiFi app you want before you buy a module.

Planning your own build?

Choosing the spa pack is one of the last decisions in a build, but the number of pumps, the heater and the control room all need planning from the start. My DIY hot tub plans include the plumbing layout and a full parts list, and The Ultimate Hot Tub Control Room Guide covers laying out the pack, pumps and heater. For parts, try parts4tubs.co.uk in the UK or parts4tubs.com in the USA.

FAQs

Is the Vian Power spa pack made by Balboa?

Yes. It’s a Balboa BP-series control system sold under the Vian brand, with a Balboa TP600 topside in Vian styling.

Is the Vian Power spa pack still available?

Yes, in the UK and Europe. As of September 2026, UK stockists list the PK-VP610 kit (with overlays) and PK-VP609 (without).

Will the Vian Power work in the USA?

It’s built for 230V 50Hz European supplies and I can’t find it sold in the USA. US builders should choose a 60Hz Balboa BP pack instead.

What’s the difference between the Vian Power and the Balboa BP8?

Both are 3kW Balboa packs with the same 18 setups. The Vian comes as a complete kit with a TP600 topside. The BP8 is sold as a pack, works with a wider range of topsides, and can control a Balboa Clim8zone heat pump directly.

Can I add WiFi to a Vian Power spa pack?

Balboa BP packs take a WiFi module, but check compatibility with your supplier first. Remember the BWA app now charges for remote (cloud) access, while the ControlMySpa app currently doesn’t.

Should I set the pack up for 16A or 32A?

That depends on the supply your electrician installs. On 16A the heater switches off while the jets are on high. On 32A they can run together, which is better in cold weather.
