Choosing a reliable hot tub seems like a minefield. What should I look for in a supplier?

Treat it like any major purchase—look for trust and credibility. Check customer reviews for both product and service, and ensure the supplier is a BISHTA member, which indicates quality and reliability.

Everyone promises great after-sales service. What makes you different?

Our customer reviews reflect the effort we've put into delivering genuine support.
We also offer a unique library of over 200 videos, 90% of which focus on helping customers with tips, water care advice, and day-to-day hot tub use.
Because water maintenance can feel tricky at first, we’ve created easy-to-follow guides to make water balancing and upkeep straightforward.

I’ve heard some dealers don’t stock spare parts. Should I be worried?

Not with us. All our models are built using high-quality, widely available components, so spare parts are never an issue.

Why are some hot tubs online very cheap while others are much more expensive?

Like cars, hot tubs vary widely in materials, design, and performance.
Price differences often reflect quality of the shell, insulation, spa system, pipework, pumps, and jets.
Unfortunately, some traders import low-quality tubs, sell them online quickly, and disappear—leaving customers without support.
If a deal looks too good to be true, it often is.
To avoid issues, choose a BISHTA member, who must follow strict standards to ensure customer safety and confidence.

“The Standards and training set by our Association are arguably the best in the world. So when you make your purchase, buy with confidence from a BISHTA member.”
Chris Hayes, BISHTA Managing Director

Does the hot tub arrive fully assembled?

Yes, the hot tub comes fully assembled—only the steps require assembly.

After delivery, what else do I need before I can start using my hot tub?

You'll need:
• A suitable electrical supply (see your model brochure for exact requirements)
• Chemicals such as chlorine or bromine
Please ensure all electrical work is completed by a qualified electrician.
We also have a dedicated Video Channel with practical guidance for all our systems.

What is the difference between chlorine and bromine?

Both are effective sanitisers. For help choosing the best one for your tub, see our Chlorine vs. Bromine guide.

What is the difference between 13-amp and 32-amp hot tubs?

13-amp tubs use a 2kW heater and are single-pump systems.
32-amp tubs use a 3kW heater and can power single or multiple pumps.
A 13-amp tub heats more slowly and uses more energy to reach temperature.

I'm unsure if my garden or home has the right access. What should I do?

You can also send images via SMS to 07740 900 197 for faster support.

We’re thinking of sinking our hot tub into the ground. Any advice?

Plan carefully and always think through the “what if” scenarios—especially access for future maintenance.
See our Sinking Hot Tubs article for tips and guidance.

What else should I do to prepare for a hot tub?

Our Hot Tub Preparation section provides detailed advice to help ensure your project runs smoothly.

Preparation Advice

What kind of base does my hot tub need?

Your hot tub must be placed on a strong, level, solid surface such as reinforced decking, concrete, or patio slabs. The base must support the full weight of the hot tub when filled with water and occupants.

I'm unsure if my garden or home has the right access. What should I do?

If you’re unsure, call us on 0116 251 3378 or email photos to customercare@hottubsuppliers.com so we can assess the access.
You can also send images via SMS to 07740 900 197 for faster support.

We’re thinking of sinking our hot tub into the ground. Any advice?

Plan carefully and always think through the “what if” scenarios—especially access for future maintenance.
See our Sinking Hot Tubs article for tips and guidance.

What is the difference between 13-amp and 32-amp hot tubs?

13-amp tubs use a 2kW heater and are single-pump systems.
32-amp tubs use a 3kW heater and can power single or multiple pumps.
A 13-amp tub heats more slowly and uses more energy to reach temperature.

Do I need to prepare the ground before installation?

Yes. Clear the area of debris, ensure the ground is level, and confirm the base can hold the required weight. A properly prepared base prevents damage and ensures safe operation.

What electrical supply do I need for my hot tub?

Hot tubs typically require either a 13-amp or 32-amp supply depending on the model.
Always refer to your hot tub’s brochure and ensure a qualified electrician carries out all electrical work.

Should I measure my garden before delivery?

Yes, accurate measurements help avoid delays. Measure:

  • Gate and pathway widths

  • Any tight corners

  • Overhead obstructions

  • Steps or uneven ground

Do I need a water supply nearby?

Just a standard outdoor hose is required to fill the hot tub. No plumbing connection is needed.

Is a crane ever required for delivery?

Sometimes, depending on access. If the hot tub cannot be safely maneuvered through your property, a crane may be necessary. We can advise once we’ve reviewed photos of your access points.

What chemicals will I need to start using my hot tub?

On day one, you’ll need either chlorine or bromine, along with pH and alkalinity balancers. We provide guidance to help you start with the correct levels.

Do I need to do anything on delivery day?

Ensure access is clear, the base is ready, and someone is present to confirm the final position of the hot tub. Having your hose and electrical supply ready helps speed up the setup process.

Maintenance Advice

How often should I test my hot tub water?

You should test your hot tub water at least 2–3 times per week. Regular testing keeps your pH, alkalinity, and sanitiser levels balanced, ensuring clean and safe water.

How frequently should I change the water in my hot tub?

We recommend draining and refilling your hot tub every 10–12 weeks, depending on usage and water quality.

How often do I need to clean or replace the filters?

Rinse filters weekly, deep clean them monthly, and replace them every 12–18 months depending on use.

Why does my hot tub water turn cloudy?

Cloudy water is usually caused by dirty filters, low sanitiser levels, or contaminants like makeup, oils, deodorant, or skincare products. Cleaning filters and balancing chemicals normally solves the issue.

What causes foam in a hot tub?

Foam often comes from soap residue, fabric softeners, body oils, cosmetics, or low calcium hardness. Using a foam reducer can help temporarily, but proper water balancing and user hygiene prevent it long-term.

How do I keep the water clear and clean?

Maintaining correct chemical levels, showering before use, cleaning filters regularly, and keeping the cover closed when not in use will keep the water sparkling and hygienic.

How much sanitiser should I use?

The ideal level is:

  • Chlorine: 3–5 ppm

  • Bromine: 4–6 ppm
    Always follow manufacturer guidelines and adjust based on test results.

What should I do if the pH keeps going out of balance?

Unbalanced pH can be caused by heavy use, rainwater, or incorrect chemical dosing. Using a pH increaser or decreaser, following test results, and ensuring correct alkalinity levels will stabilise it.

How do I maintain the hot tub cover?

Clean the cover with a mild cleaner monthly or spa cover shine, condition the vinyl to prevent cracking, and keep it secured to avoid heat loss, debris, and damage.

Should I leave my hot tub running all the time?

Yes. Hot tubs are designed to run continuously. This keeps water filtering properly and maintains a stable temperature, which is more energy-efficient than reheating from cold.

Do I need to shock the water?

Yes. Shocking the hot tub once a week helps break down organic waste, improves clarity, and resets sanitser effectiveness.

About Balboa

Who are Balboa?

Balboa Water Group is one of the world’s most trusted manufacturers of hot tub control systems, pumps, heaters, and electronic components. Their technology is used in premium hot tubs worldwide.

Why do many hot tubs use Balboa control systems?

Balboa systems are known for their reliability, energy efficiency, smart features, and long lifespan. They’re easy to use and supported globally, making them one of the top choices for spa manufacturers.

What makes Balboa systems more reliable?

Balboa uses patented M7 technology, which features dual temperature sensors and eliminates the need for external pressure switches. This creates fewer failure points and ensures safer, more accurate temperature control.

Are Balboa control panels easy to use?

Yes. Balboa panels feature simple, intuitive buttons, clear displays, and straightforward menus, allowing users to adjust temperature, jets, lights, and filtration settings with ease.

Are Balboa parts easy to replace?

Yes. Balboa components are standardised and widely available, which means replacement parts such as heaters, pumps, and circuit boards are easy to source and service.

Can Balboa systems reduce running costs?

Balboa’s advanced heating and control technology is designed for high energy efficiency, helping maintain stable water temperature while reducing electricity consumption.

Do Balboa systems work with smartphone apps?

Many Balboa systems support Wi-Fi modules, allowing you to control your hot tub from your smartphone—adjusting temperature, scheduling filtration, and activating features remotely.

How long do Balboa heaters and pumps typically last?

With proper care and correct water balance, Balboa heaters and pumps often last many years. Their components are designed for long-term performance under demanding spa conditions.

What should I do if my Balboa system shows an error code?

Error codes usually indicate temperature issues, low water flow, heater faults, or sensor problems.
Most issues can be solved by checking water levels, filters, or resetting the system. Persistent errors should be assessed by a qualified technician.

Energy Efficiency

How much does a hot tub cost to run each month?

Running costs vary by model, insulation quality, usage, and electricity rates. Modern, well-insulated hot tubs typically cost £3–£5 per day, while premium energy-efficient models can cost even less.

What is the most important factor in hot tub energy efficiency?

Insulation is the biggest factor. A well-insulated shell, cabinet, and base dramatically reduce heat loss and lower running costs.

Should I keep my hot tub running all the time?

Yes. Hot tubs are designed to stay running. Maintaining a steady temperature is more efficient than reheating from cold every time you use it. Economy modes can also be used for added efficiency. 

What temperature is most energy efficient?

Most users find 36–38°C comfortable. Lowering the temperature by even 1–2°C can reduce energy consumption.

How important is the hot tub cover?

Very important. A high-quality, insulated, well-fitting cover prevents heat loss, reduces evaporation, protects the water, and can cut running costs by up to 25%. At Hot Tub Suppliers we supply extra thick covers which are up to 12cm in depth. 

How often should I run filtration cycles to save energy?

Follow the manufacturer’s schedule. Modern hot tubs use low-energy circulation pumps, making filtration cycles efficient. Running filtration as programmed prevents overheating, cloudy water, and unnecessary energy use.

Does location affect energy efficiency?

Absolutely. Placing your hot tub in a sheltered area (out of strong winds) and away from exposed open spaces reduces heat loss. Surrounding fencing, walls, or a gazebo can also help.

Can I use the economy mode to reduce energy use?

Yes. Most modern hot tubs have Ready & Rest modes, which lower the temperature or limit heating to filtration cycles—helpful when you're away or not using the tub regularly.

Do modern hot tubs use less energy than older models?

Yes. Newer hot tubs offer:

  • Better insulation

  • More efficient pumps

  • Smart control systems

  • Improved covers
    These updates significantly lower operating costs.

Will a heat pump reduce my hot tub running costs?

In many cases, yes. A heat pump can reduce heating costs by up to 60–70% depending on usage and climate. However, it requires space, airflow, and correct installation.

Holiday Let Advice

Do I need a specific type of hot tub for a holiday let?

Yes. Holiday lets require commercial-grade HSG 282, durable hot tubs designed for frequent use and easy maintenance. Look for models with strong insulation, high-efficiency filtration, and reliable components such as Balboa systems.

Are there legal or safety regulations for hot tubs in holiday accommodation?

Yes. Hot tubs in rental properties must comply with HSG282 guidelines, which cover water care, disinfection, filtration, turnover times, and guest information.
Choosing a BISHTA-approved supplier ensures your hot tub meets these standards.

What is HSG282 and why is it important?

HSG282 is a UK Health & Safety guideline specifically for hot tubs used in holiday lets.
It ensures hot tubs are:

  • Safe for high turnover of guests

  • Disinfected properly

  • Equipped with continuous filtration

  • Easy to maintain
    Compliance protects your guests — and protects your business legally.

Do I need a 32-amp hot tub for a holiday let?

Most holiday-let hot tubs are 32-amp, as they heat quicker, run multiple pumps, and maintain temperature more efficiently — ideal for back-to-back guest changeovers.

How much maintenance is required between guest stays?

Daily and changeover maintenance typically includes:

  • Testing water chemistry

  • Shock-dosing

  • Cleaning filters

  • Checking water level

  • Ensuring the cover is secure
    These steps ensure compliance with HSG282 and keep water safe for the next guests.

Should the hot tub be emptied between every booking?

Yes, to comply with guidelines the water should be changed between each guests. 

What chemicals do I need for a holiday let hot tub?

Holiday lets usually use bromine, as it stays stable for longer and is gentler on skin.
You’ll also need pH balancers, shock, and test strips or digital testers.

How long does a holiday let hot tub take to heat up?

A 32-amp hot tub typically takes 8–12 hours to heat from cold depending on size.

Do I need signage for guests?

Yes. HSG282 recommends visible safety notices covering:

  • Showering before use

  • No alcohol or glass

  • Maximum bathing times

  • Health warnings

  • Children supervision

At Hot Tub Suppliers we supply these all of our commerical hot tubs.

We also stock them on our website, click here to view them. 

Do you offer maintenance plans for holiday lets?

Yes. We offer servicing packages for holiday lets, including chemical checks, filter cleaning, regular servicing, and emergency call-outs.

Can I restrict guest settings on the hot tub?

Yes, our Lodgic 282 model has a separate control panel for guests to use. 

What size hot tub is best for a holiday rental?

The most popular sizes are 5–7 seaters, as they suit families, groups, and couples.

Will having a hot tub increase my booking rates?

Absolutely. Hot tubs are one of the most requested features in UK holiday rentals.
Many owners see higher occupancy, more repeat customers, and increased nightly rates after installation.
