FreshWater IQ for Caldera Spas

FreshWater IQ helps owners of compatible Caldera spas understand their water care. Its Salt System and Smart Monitoring System do different jobs; newer compatible installations can also use a separate Dosing System.

What is included at Ultimate Hot Tubs?

Salt System included with Utopia: at Ultimate Hot Tubs, the FreshWater Salt System comes as standard with the Caldera Utopia range. For other compatible Caldera hot tubs it is available at extra cost. This offer does not apply to Fantasy spas or Endless Pools.

The Salt System and IQ Smart Monitoring are separate components. Ask us to confirm the monitoring, dosing or connected equipment supplied with your chosen spa.

Choose the equipment for your spa

Utopia: Salt System included as standard. Confirm the IQ monitoring setup in your quotation.
Paradise and compatible Vacanza: Salt System available at extra cost. Ask us to confirm model-year compatibility.
Fantasy and Endless Pools: this Caldera salt-system offer does not apply.

For a useful quotation, tell us your chosen Caldera model and ask which water-care components, installation and ongoing consumables it covers.

Ask About Your Spa’s Water Care

FreshWater Salt System: better water, less hassle

The FreshWater Salt System uses a replaceable titanium cartridge to turn a low level of salt into chlorine. It helps keep your spa water clean while reducing the amount of sanitiser you need to add by hand.

Natural-feeling water: fewer chemical additions can mean softer-feeling water and fewer harsh odours. Caldera describes it as gentler on skin and eyes.
Fewer drains and refills: properly maintained water can last up to a year, helping conserve water and reduce refill costs. Water chemistry and the number of bathers affect how long it lasts.
Less routine dosing: chlorine is generated automatically at your chosen output setting, leaving more time to enjoy your spa.

Simple cartridge replacement

The cartridge sits inside the spa and can be changed without tools. Each cartridge lasts up to four months; a three-pack can cover a year when the system is properly maintained. The cartridge needs no cleaning, but the spa still needs its regular water checks and maintenance.

Read Caldera’s Salt System guidance and water-life conditions.

Optional silver-ion water care

Caldera also suggests an optional silver-ion cartridge alongside the Salt System. Ask our team about a compatible Monarch silver cartridge and local availability for your spa.

FreshWater IQ: cleaner water, simpler care

FreshWater IQ adds in-line Smart Monitoring to compatible salt-equipped Caldera spas, helping you understand what your water needs.

Self-monitoring: checks pH, chlorine and salt levels every hour.
Clear guidance: readings and recommended next steps appear on the spa’s control panel.
Consistent water care: regular information helps you spot when sanitiser or water balance needs attention.
Less time and effort: practical prompts make routine care easier to follow.
A low level of salt: the Salt System provides the chlorine; this is still sanitised spa water and still needs appropriate water-care products.
Care for your spa: keep water balanced and follow the maintenance schedule for your equipment as well as your bathing comfort.

Smart Monitoring provides advice. It does not automatically make every adjustment. Separate compatible Dosing equipment can dispense pH Up, pH Down or Phosphate Remover with a tap; a compatible Connected Spa Kit adds supported phone controls.

Salt generation and smart monitoring: what is the difference?

The FreshWater Salt System converts salt into chlorine to sanitise the water. Smart Monitoring measures pH, chlorine and salt and provides readings and advice. It needs the compatible Salt System installed and operating correctly.

Having a salt system alone does not mean a spa has FreshWater IQ monitoring. For owners, the useful difference is a regular view of water conditions and guidance about adjustments.

Which Caldera spas can use FreshWater IQ?

The Salt System is available on 2019 and newer Utopia and Paradise spas, with compatible Vacanza models added from 2025. Salt compatibility and IQ monitoring compatibility are different.

Caldera’s smart-monitoring guidance identifies Utopia and Paradise spas made from January 2024 onwards. Older spas are not compatible with this monitoring system.

Vacanza has salt-system compatibility from the 2025 model year, but does not support IQ Smart Monitoring or Dosing. Fantasy does not support FreshWater IQ.

Ask us about FreshWater IQ availability for your chosen spa. We will check the model year and equipment and confirm what is in your quotation.

What about dosing and the Caldera app?

Current manufacturer information describes separate dosing equipment for compatible Utopia and Paradise spas. With this fitted, an owner can dispense pH adjustment or phosphate-removal products at a touch. It is not a feature of every IQ installation.

The spa’s control panel can operate IQ without an app. Remote features require a compatible Connected Spa Kit and Wi-Fi connection, as well as the relevant water-care equipment. Ask us to confirm the setup for your spa.

Water care still needs your attention

Follow your spa and water-care manuals, check the water before use and carry out routine maintenance. Smart Monitoring does not measure every water-care parameter: separate checks are still needed for alkalinity, calcium hardness and phosphates.

We can help you understand the equipment and care routine before you decide. Visit our Atherstone showroom, send an enquiry or call 0121 767 9122.

13amp vs. 32amp Hot Tubs: Which One Is Right for You?

Keith Bryers — Thu, 20 Mar 2025 11:29:58 +0000

13amp vs 32amp Hot Tubs: Whats the difference?

Choosing the perfect hot tub for your home is an exciting process, but one of the key decisions you’ll need to make is whether to go for a 13amp plug-and-play hot tub or a 32amp hard-wired hot tub. While both options offer fantastic hydrotherapy and relaxation benefits, they differ in terms of power, performance, and installation requirements.

In this guide, we’ll break down the differences between 13amp and 32amp hot tubs, helping you determine which is the best fit for your lifestyle.

What Is a 13amp Hot Tub?

A 13amp hot tub, often referred to as a plug-and-play model, is designed to run on a standard household electrical socket. This makes it incredibly easy to install, as it does not require any special electrical work beyond a dedicated outdoor socket.

Key Features of 13amp Hot Tubs:

✅ Easy Installation – Simply plug into a standard outdoor socket and enjoy.

✅ Lower Running Costs – Consumes less electricity than 32amp models.

✅ Ideal for First-Time Owners – Simple to set up and use.

✅ Portable – Can be easily relocated if needed.

Limitations of 13amp Hot Tubs:

❌ Limited Heater & Pump Power – Many 13amp models cannot run the heater and jets at full power simultaneously, meaning water temperature may drop when jets are in use.

❌ Fewer Jets & Features – Typically has fewer jets and lower pump power than 32amp models.

❌ Slower Heating Times – Takes longer to heat up compared to 32amp hot tubs.

What Is a 32amp Hot Tub?

A 32amp hot tub is a more powerful and premium option that requires a dedicated hard-wired electrical connection installed by a qualified electrician. These models are designed for superior hydrotherapy performance and enhanced features.

Key Features of 32amp Hot Tubs:

✅ Powerful Performance – Can run the heater and jets simultaneously without losing temperature.

✅ More Jets & Stronger Pumps – Delivers a more intense massage experience.

✅ Faster Heating Times – Reaches desired temperature quicker than 13amp models.

✅ Additional Features – Often includes extras like LED lighting, waterfalls, audio and advanced filtration.

Limitations of 32amp Hot Tubs:

❌ Requires Professional Installation – Must be wired by a certified electrician.

❌ Higher Upfront Cost – More expensive due to increased power and features.

Which Hot Tub Is Best for You?

The best hot tub for you depends on your budget, usage, and installation preferences. Here’s a quick comparison to help you decide:

Feature	13amp Hot Tub	32amp Hot Tub
Installation	Plug-and-play, no electrician required	Needs professional installation
Performance	Cannot run heater and jets at full power together	Can run heater and jets simultaneously
Number of Jets	Fewer jets, lower power	More jets, higher power
Heating Speed	Slower heating times	Faster heating times
Running Costs	Lower electricity usage	Can be more efficient – more insulation
Ideal For	First-time buyers, casual users	Frequent users, hydrotherapy enthusiasts

Choose a 13amp Hot Tub If…

• You want a simple, budget-friendly option with easy installation.

• You plan to use your hot tub occasionally rather than daily.

• You don’t mind a slower heating time and a slight temperature drop when using jets.

Choose a 32amp Hot Tub If…

• You want a high-performance hot tub with strong hydrotherapy jets.

• You plan to use your hot tub regularly, even in winter.

• You want to enjoy the heater and powerful jets simultaneously.

Final Thoughts: Which One Should You Buy?

If you’re new to hot tubs and looking for a cost-effective and easy-to-install option, a 13amp hot tub is a fantastic choice. However, if you want the best hydrotherapy experience, faster heating times, and advanced features, a 32amp hot tub is well worth the investment.

Hot Tub Installation Guide

Your Comprehensive Guide to Hot Tub Installation

So, you’ve decided to take the plunge and invest in a luxurious hot tub for your home. Congratulations! Get ready to elevate your relaxation game to a whole new level. But before you start envisioning serene soaks under the stars, it’s essential to ensure a smooth and successful installation process. Fear not, because we’ve got you covered with this comprehensive hot tub installation guide.

1. Plan Your Space:

Before your hot tub arrives, take some time to carefully plan its placement. Consider factors such as accessibility, privacy, and aesthetics. Make sure you have enough space for both the tub and any necessary accessories like steps and a cover lifter.

2. Prepare the Foundation:

Hot Tub Concrete Base

A sturdy and level foundation is crucial for the longevity and performance of your hot tub. Concrete pad, patio, or a reinforced decking area are all excellent options. Ensure the surface is properly prepared and can support the weight of the tub, water, and occupants.

3. Arrange for Electrical Setup:

Hot tubs require a dedicated electrical circuit, typically from 13 amp to 32 amps. Instruct a licensed electrician to handle the wiring and ensure compliance with safety standards. Never attempt to DIY electrical work, as it can be extremely dangerous. We can recommend local electricians please contact us.

4. Plan for Water and Drainage:

Consider the logistics of filling and draining your hot tub. You’ll need access to a water source for filling and a suitable drainage area for emptying. A nearby hose hookup and a floor drain are convenient solutions.

5. Schedule Delivery and Installation:

Coordinate with your hot tub supplier to schedule delivery and installation. Ensure that your chosen location is accessible to the delivery team and that they have clear instructions for placement.

6. Follow Manufacturer’s Instructions:

Once your hot tub is in place, carefully follow the manufacturer’s instructions for setup and initial operation. This includes filling the tub, priming the pump, and balancing the water chemistry. As part of our in-house delivery and installation service we complete this for you and discuss water management.

7. Consider Safety Measures:

Safety should always be a top priority when enjoying your hot tub. We install a locking cover to prevent unsupervised access, especially if you have young children or pets. Additionally, consider adding non-slip mats or handrails for added stability.

8. Regular Maintenance:

To keep your hot tub running smoothly, establish a regular maintenance routine. This includes testing and adjusting water chemistry, cleaning the filter, and inspecting components for wear and tear. Refer to your owner’s manual for specific guidelines or please contact us.

9. Enjoy Your Oasis:

With proper installation and maintenance, your hot tub will provide many years of relaxation and enjoyment. Soak away stress, soothe tired muscles, and create lasting memories with friends and family in your very own backyard oasis.

By following these steps, you can ensure a hassle-free hot tub installation process and start reaping the benefits of hydrotherapy right away. Now go ahead, indulge in the ultimate relaxation experience – you deserve it!
