A hot tub is often seen as a symbol of relaxation and luxury, but before you take the plunge, it’s important to understand its associated running costs. From electricity to maintenance, there are several factors to consider. This blog will break down the costs associated with operating a hot tub in the UK and provide tips on how to keep expenses manageable.
Whether you’re a prospective owner or a current user looking to optimise your costs, this guide will answer your questions and help you make informed decisions.
What Are the Main Costs of Running a Hot Tub?
The cost of running a hot tub varies depending on various factors such as the model, frequency of use, and energy tariffs. Here are the key components that make up its running costs:
1. Electricity Costs
The electricity bill is usually the largest ongoing expense for a hot tub owner. On average, a standard hard-shell hot tub uses between 3.5 and 6 kWh of energy daily. This translates to £1–£2 per day, assuming an energy tariff of 33.2p per kWh. For efficient models, these costs may be as low as £1 per day.
However, lower-quality hot tubs or inflatable models can cost upwards of £5 per day due to poor insulation and less efficient heating systems.
2. Maintenance and Servicing
To keep your hot tub in good working condition, regular servicing is essential. Annual maintenance costs range between £150 and £200, depending on whether you opt for a one-off service or a subscription service plan.
3. Water Care and Filters
You’ll also need water treatment chemicals and replacement filters to maintain water quality. These consumable expenses typically cost between £250 and £350 per year.
4. Water Usage
A hot tub holds a significant amount of water and has to be refilled multiple times a year, depending on usage and hygiene practices. While water usage costs are generally lower than electricity, they can still be a factor to consider when estimating overall running costs.
Factors That Influence Hot Tub Running Costs
1. Hot Tub Size and Model
Larger hot tubs naturally require more energy to heat and maintain, as they hold more water. Higher-end models with advanced insulation and energy-efficient components tend to have lower running costs over time.
2. Frequency of Use
The more you use your hot tub, the more energy it consumes. Jets, in particular, use additional power when activated.
3. Water Temperature
Maintaining a higher water temperature (above 38°C) will increase electricity usage. Consider lowering the temperature slightly or turning it down when not in use.
4. Insulation Quality
Well-insulated hot tubs lose less heat and cost less to run. Look for models with multi-layered foam insulation and a quality thermal cover to retain heat effectively.
5. Energy Tariff
Your electricity provider and tariff play a critical role in your hot tub’s running costs. Switching to a cheaper energy plan can lead to significant savings.
6. Location
Placing your hot tub in a sheltered area protected from wind and weather can help to retain heat. Exposed locations can increase energy consumption as the heater works harder to maintain the desired water temperature.
How to Reduce Hot Tub Running Costs
Fortunately, there are several easy ways to lower the cost of operating a hot tub. Here are some of the most effective strategies:
1. Upgrade Your Insulation
Invest in a high-quality, well-fitting hot tub cover and consider adding a floating thermal blanket to reduce heat loss.
2. Maintain Your Filters
Dirty filters can restrict water flow, overworking the pump and increasing energy consumption. Clean or replace filters regularly to ensure your system operates efficiently.
3. Use Economy Mode
Modern hot tubs often have energy-saving settings like “eco mode” or “sleep mode,” which can reduce power usage when the hot tub isn’t in use.
4. Lower the Temperature
Adjusting the water temperature by just a degree or two can result in noticeable savings over time. If you’re away for an extended period, reduce it even further.
5. Switch Energy Providers
Shop around for the best electricity rates using a comparison site. Even a small reduction in your tariff can result in significant yearly savings.
6. Plan Upgrades Wisely
If you have an older or inflatable hot tub, consider upgrading to a newer, energy-efficient model. Although the upfront cost may be higher, the savings in running costs will pay off in the long run.
Why Owning a Hot Tub is Worth It
Despite the running costs, owning a hot tub comes with numerous physical and mental health benefits. It provides an unparalleled way to relax, improve sleep, and spend quality time with family or friends. With proper maintenance and energy-saving strategies, the expense becomes a reasonable trade-off for the luxury and wellness benefits a hot tub offers.
FAQ on Hot Tub Running Costs
How Much Does It Cost to Run a Hot Tub Per Month?
For a well-insulated, high-quality hot tub used multiple times per week, you can expect to pay between £30 and £60 per month for electricity. Adding maintenance and water costs, the total monthly expense may range between £65 and £90.
How Much Does It Cost to Run a Hot Tub in the UK?
The average annual running cost for a standard hard-shell hot tub in the UK is between £760 and £1,270, depending on energy efficiency, usage, and maintenance practices.
Is It Cheaper to Keep a Hot Tub on All the Time?
Surprisingly, yes! It’s more cost-effective to maintain your hot tub at a consistent temperature instead of allowing the water to cool and reheating it frequently. Modern hot tubs are designed to retain heat efficiently, so keeping them at a steady temperature uses less energy.
Do Hot Tubs Use a Lot of Electricity?
Hot tubs do require a consistent energy supply, but their electricity usage can be optimised by choosing an energy-efficient model, using proper insulation, and maintaining it regularly. Poorly insulated or inflatable hot tubs, on the other hand, can significantly increase electricity usage.
Make an Informed Decision
Understanding the ongoing costs of operating a hot tub is crucial for making an informed purchase or optimising your current setup. By choosing an energy-efficient hot tub, maintaining it well, and implementing cost-saving measures, you can enjoy all the benefits of hot tub ownership without an overwhelming impact on your budget.
