What is a Swim Jet System and How Does It Work?

Ever wished you could swim for kilometres right in your own backyard, without needing an Olympic-sized pool? A swim jet system makes that a reality. In simple terms, think of it as a 'treadmill for swimmers'. This clever technology uses a powerful pump and specially designed jet outlets to push a strong, continuous current of water towards you. By swimming against this flow, you remain in one spot, getting a fantastic workout in even the most compact pool. These systems are the core technology behind what experts call counter-current swimming machines, effectively transforming any pool into an endless swimming lane.

Not all currents are created equal. When exploring swimjet systems, you'll find two main technologies, each offering a distinct swimming experience. Understanding this difference is key to choosing the right fit for your needs.

Jet-Based Systems vs. Turbine Systems: What's the Difference?

Most common systems use high-pressure jets. These push water through smaller nozzles, creating a powerful but narrower stream. The experience can feel more turbulent or bubbly, which some people enjoy for resistance training. In contrast, premium turbine systems use a propeller to move a much larger volume of water at lower pressure. This generates a wide, deep, and river-like current that is incredibly smooth, making it ideal for serious swimmers focusing on their technique.

Key Terminology Explained for Beginners

Getting to grips with the technical terms is easy. Here are the key ones you'll see:

Flow Rate (LPM/GPM): This measures how much water the system moves, in Litres Per Minute or Gallons Per Minute. A higher flow rate generally means a stronger current to swim against.
Counter-Current: This is the simple principle at work. The system creates a current flowing against you, which is what allows you to swim in place without moving forward.
Variable Speed Control: A crucial feature that lets you adjust the current's strength. This is perfect for warming up, intense training, or a gentle, relaxing swim.

Who are Swim Jet Systems For?

These systems are incredibly versatile and are a fantastic addition for almost any Kiwi pool owner. They are perfect for:

Fitness Enthusiasts: Get a full-body, low-impact cardio workout without leaving home.
Athletes & Triathletes: Train for endurance and perfect your stroke with a consistent, adjustable current.
Families: Turn down the speed and create a fun 'lazy river' effect for the kids to enjoy.
Rehabilitation: Use the gentle resistance of the water for hydrotherapy and recovery from injuries.

The Top 5 Benefits of Installing a Swim Jet in Your Pool

A pool is a significant investment in your home and lifestyle. But what if you could transform it from a place for a weekend splash into a year-round centre for fitness, therapy, and family fun? That's the power of modern swimjet systems. They go far beyond creating a simple current, unlocking the full potential of your pool and maximising your investment.

Here are the top five benefits of adding a swim jet to your backyard pool.

1. Unlock Your Pool's Fitness Potential

Imagine swimming for as long as you want without a single turn. A swim jet creates a smooth, powerful current that holds you in place, turning even a compact Kiwi pool into an endless lap lane. It’s perfect for serious swim training or a daily cardio workout. But it's not just for swimming; the adjustable resistance is brilliant for:

Water-based strength training: Use the current for resistance to build muscle effectively.
High-energy aquarobics: Add a new level of challenge to your water fitness routines.
Cross-training: An ideal, low-impact complement to running or cycling.

2. Enjoy Therapeutic and Low-Impact Rehabilitation

For anyone recovering from an injury or managing joint pain like arthritis, exercising in water is a game-changer. The natural buoyancy supports your body, reducing stress on joints and allowing for gentle movement. A swim jet enhances this by providing a controlled, adjustable current for progressive rehabilitation. The therapeutic properties of water, such as hydrostatic pressure, are known to improve circulation and soothe sore muscles, turning your pool into a private hydrotherapy facility.

3. Create More Fun for the Whole Family

Beyond fitness and therapy, a swim jet brings a new level of excitement to your pool. Turn down the current to create a gentle 'lazy river' for the kids to float on, or turn it up for some fun resistance play with boogie boards. It transforms a standard backyard pool into a dynamic water park, providing hours of entertainment for friends and family of all ages.

Ultimately, installing one of these advanced swimjet systems is about getting more from your pool. It bridges the gap between leisure and performance, giving you a convenient, versatile, and enjoyable facility right in your own backyard.

Installing a Swim Jet: A Guide for New Builds vs. Existing Pools

One of the biggest questions we hear is, "Can I install a swim jet in my pool?" The great news is that modern swimjet systems can be installed in almost any type of pool, whether you’re building from scratch or upgrading an old favourite. The key difference lies in the planning and installation method.

While it’s a technical job, it’s a straightforward process for a qualified professional. Let’s break down what’s involved for both new and existing pools.

Planning for a Swim Jet in a New Pool

Integrating a swim jet during the construction phase is the ideal scenario. It allows all plumbing and electrical lines to be hidden neatly within the pool's structure for a seamless, built-in finish. You can work with your pool builder to position the jets perfectly-usually in the centre of a long wall-to create the smoothest, most effective current for your swimming style. This pre-planning ensures the pool shell (whether concrete, fibreglass, or liner) is properly reinforced to support the unit for a lifetime of hassle-free use.

Retrofitting a Swim Jet to an Existing Pool

Want to add endless swimming to your current pool? You have excellent options. For major renovations, a 'through-the-wall' system can be installed by cutting into the pool shell. However, a far less invasive and popular choice is an 'over-the-wall' or 'deck mount' unit. These self-contained systems simply hang over the pool edge and are secured to the deck. The main challenge is running the plumbing and electrical wiring to the pump unit discreetly, but a skilled installer can find clever solutions.

The Installation Process: What to Expect

No matter which path you choose, a professional installation follows a clear, methodical process to ensure safety and performance. Here’s a simple overview of the steps involved:

Step 1: Site Assessment & Planning. An expert will visit your property to assess your pool, discuss your goals, and recommend the best system and placement.
Step 2: Core Drilling & Plumbing. For built-in systems, this involves carefully cutting openings in the pool wall. The team will then install the jet housing and run all the necessary pipework to the pump location.
Step 3: Electrical Connection. This is a crucial step. A registered New Zealand electrician must complete all wiring to ensure your system is safe, compliant, and correctly connected to a dedicated circuit.
Step 4: Commissioning & Testing. Once everything is connected, the installer will start the system, check for leaks, and test the flow to make sure it’s delivering the powerful, smooth current you expect.

From start to finish, relying on experienced professionals is the best way to guarantee your new swim jet system is installed correctly, safely, and is ready to transform your backyard pool.

How to Choose the Right Swim Jet System for Your NZ Pool

Choosing the right swim jet system can feel like a big decision, but it doesn't have to be complicated. By focusing on how you plan to use your pool, you can easily narrow down the options and find the perfect fit for your family's needs. As New Zealand's pool specialists, we're here to help you ask the right questions and make a confident choice.

Assess Your Primary Use and Skill Level

The first step is to think about who will be using the swim jet and for what purpose. A family looking for casual fun and light exercise has very different needs from a competitive swimmer training for an event. Is your goal gentle hydrotherapy, a challenging workout, or a bit of both? For households with multiple users, a system with variable speed control is essential. This allows you to create a gentle current for the kids or a powerful flow for a serious training session, all at the touch of a button.

Essential Features to Look For in 2025

Modern swimjet systems come packed with technology designed to improve your experience and reduce running costs. When getting quotes, be sure to ask about these key features:

Variable Flow Control: Look for multi-speed or fully variable options to precisely control the current's strength for different activities and swimmers.
Smart Controls: Wireless remotes or smartphone app integration offer ultimate convenience, letting you adjust settings without leaving the water.
Energy Efficiency: A system with a Variable Speed Drive (VSD) motor will be significantly cheaper to run, saving you money on power bills in the long run.
Integrated LED Lighting: Built-in lighting adds beautiful ambiance for evening swims and enhances safety after dark.

Understanding the Costs and Maintenance of a Swim Jet

A swim jet is a fantastic investment in your health and lifestyle, but it's important to understand the full picture of ownership. We believe in providing clear, upfront information to help you make the best decision. The good news is that modern swimjet systems are designed for impressive efficiency and surprisingly simple upkeep, making them a practical addition to your Kiwi home.

The Total Cost of a Swim Jet System in NZ

The total investment is broken into two main parts: the unit itself and the installation. In New Zealand, the cost of a swim jet unit can vary significantly. You can find entry-level or simpler systems starting from around NZ$5,000, while more powerful, feature-rich, or premium models can range from NZ$15,000 to over NZ$30,000. Installation costs typically range from NZ$2,000 to NZ$15,000+, influenced by factors like:

Whether it’s being fitted to a new or existing pool (retrofitting).
The type of pool construction (concrete, fibreglass, etc.).
Site access for tradespeople and equipment.
The extent of required plumbing and electrical work.

Ongoing Running Costs and Energy Consumption

Worried about your power bill? You’ll be pleased to know that running a swim jet is very economical. Many high-quality systems feature a Variable Speed Drive (VSD), allowing you to adjust the current's intensity. This means you only use the power you need. A typical 30-minute swimming session can cost less than a dollar in electricity-often less than running a spa pool heater or a large heat pump for an hour.

Simple Maintenance for Long-Term Performance

Maintaining your swim jet is straightforward and requires just a few simple habits to ensure it performs flawlessly for years. The key is consistency.

Keep Intakes Clear: Regularly check that the water intake grates are free from leaves and other debris to ensure optimal water flow.
Balance Your Water: Well-maintained pool water chemistry is crucial. Balanced water protects the internal components of your swim jet from corrosion or scaling.
Follow Manufacturer Advice: An occasional professional service, as recommended by the manufacturer, will keep your system in peak condition.

By understanding these costs and simple care routines, you can confidently invest in an endless swimming experience. If you have more questions, the team of experts at Pool Robots NZ is always ready to help.

Can a swim jet be installed in any type of pool?

Yes, swim jets are highly versatile and can be installed in most pool types, including concrete, fibreglass, and vinyl liner pools. For new pool constructions, a "through-wall" unit is built directly into the pool shell for a seamless look. For existing pools, "over-the-wall" or deck-mounted units are an excellent retrofitting option, allowing you to add an endless swimming experience without major renovations. Our experts can help you find the right fit for your specific pool.

How much power does a swim jet use and will it raise my electricity bill significantly?

A typical swim jet motor uses between 2.5 to 4 kilowatts (kW) of power. Based on average New Zealand electricity rates, running a 3kW system for an hour would cost approximately NZ$0.90 - NZ$1.20. When used for regular 30-minute training sessions a few times a week, the impact on your monthly power bill is quite moderate. It's an energy-efficient way to get a full-body workout at home without the cost of heating a large lap pool. The igarden swimjet Costs $0.26 cents per hour to operate oh high speed

How much does a swim jet system cost to buy and install in New Zealand?

In New Zealand, the cost varies depending on the power and features of the unit. The swim jet unit itself can range from around NZ$5,000 to over NZ$25,000 for high-performance systems. Professional installation, which includes plumbing and electrical work, typically adds an additional NZ$2,000 to NZ$5,000. It's a valuable investment for turning your backyard pool into a complete fitness and recreation hub. The iGarden swimjet provides a professional level swimjet system at a price that wont break your budget

Is a swim jet system noisy to operate?

Modern swim jet systems are designed for quiet operation. The primary sound you'll hear is the therapeutic rush of the water current itself, not a loud mechanical motor. The pump is usually located with your other pool equipment, away from the poolside, minimising noise. The experience is generally considered to be peaceful and no more disruptive than a spa pool's jets, allowing you to focus on your swim without any distracting noise.

Can you adjust the strength of the water current?

Absolutely. Nearly all modern swim jets feature adjustable current strength, making them suitable for everyone from gentle hydrotherapy users to competitive swimmers. The controls are conveniently located, often as a dial on the unit itself or via a poolside button or remote control. This allows you to easily vary the intensity for a leisurely swim, resistance training, or a challenging workout, all in the same session. It’s a key feature that provides great versatility.

What is the difference between a swim jet system and a dedicated swim spa?

The main difference is that swimjet systems are components added to a new or existing swimming pool, transforming a larger body of water into a swimming treadmill. In contrast, a swim spa is a smaller, self-contained unit that comes with its own shell, heating, and built-in jets. A swim jet offers the flexibility to use your full-sized pool, while a swim spa is an all-in-one, compact solution that often fits in smaller spaces.
