Running costs of a hot tub
Running a hot tub comes with various costs, including electricity usage, servicing and maintenance expenses, as well as the cost of consumables and water care products.
Navigating the realm of hot tub electricity usage isn’t as daunting as it seems. The main thing to understand is that hot tubs leverage an electric heater to warm the spa water to your desired temperature.
Both the size and model, alongside ambient temperature, frequency, duration of use, jet usage and preferred water temperatures influence a tub’s energy consumption. Fun fact: A titanium hot tub heater conducts heat more efficiently than its stainless steel counterpart! Regardless of their kW rating – which only affects how quickly they heat up – heaters don’t significantly alter energy usage.
With high-density foam insulated models being more energy-efficient and air-source heat pumps available for heating cost reduction, you can find ways around bumping up those kilowatt-hours on your electricity bill.
Servicing and maintenance
Keeping your hot tub running smoothly involves regular servicing and maintenance. This can include tasks such as checking the water quality, adjusting pH levels, cleaning filters, and ensuring the heater functions optimally. Ignoring routine check-ups can lead to operational inefficiencies that might ramp up your energy bills over time.
You have a few options here: either take on these chores yourself or opt for professional help with hot tub service plans. A typical service plan encompasses comprehensive checks of all vital hot tub electrical components, plumbing systems, and insulation layers – often carried out by certified hot tub service engineers who adhere to rigorous industry standards like BISHTA or SGS guidelines.
Servicing costs can vary depending on the frequency (monthly/quarterly/yearly) and level (DIY/basic/premium) of services availed but tend to range from £150-£700 per year approximately.
Irrespective of your choice between DIY efforts or expert services, what’s crucial is never to overlook any signs of malfunction in your home spa!
Consumables and water care products
Keeping your hot tub water clean and balanced is a crucial aspect of running costs that’s often overlooked. It involves investing in essential consumables and water care products. Hot tub owners need to maintain a small supply of chemicals, sanitisers or saltwater systems to maintain the right pH levels in their spa.
These items ensure your hot tub remains hygienic, preventing corrosion or damage caused by imbalanced water conditions. Moreover, consider the cost of replacing filters which play a pivotal role in managing your hot tub’s cleanliness while enhancing its performance overall.

Factors affecting hot tub energy consumption
Insulation, temperature settings, water conservation, and filter cleaning all play a role in the energy consumption of a hot tub.
Proper insulation is a key factor in controlling the running costs of your hot tub. Hot tubs that lack sufficient insulation can result in daily running costs increasing up to five or six times.
However, hot tubs with high-density foam insulation are more energy-efficient and help to retain heat effectively, reducing energy consumption and ultimately saving you money on your electricity bills.
Additionally, a well-insulated hot tub will also ensure that the water remains at a consistent temperature for longer periods, allowing you to enjoy your relaxing soak without constantly having to reheat the water.
The temperature settings of your hot tub can have a significant impact on its energy consumption and running costs. The higher the water temperature, the more energy it takes to heat and maintain it at that level.
So, if you want to minimise your energy usage and reduce your electricity bills, consider lowering the temperature slightly. Even a small decrease can make a noticeable difference in running costs over time.
It’s also worth keeping in mind that ambient temperature plays a role – if your hot tub is located outdoors in colder climates, it will require more energy to maintain the desired temperature compared to an indoor one.
Conserving water is not only good for the environment, but it can also help lower your hot tub running costs. Hot tubs require a certain amount of water to operate effectively, and constantly refilling and heating that water can be expensive.
By taking simple steps to conserve water, you can reduce both your usage and your bills. For example, regularly checking for leaks in the plumbing system and fixing them promptly can prevent unnecessary water wastage.
Additionally, using a thermal floating blanket when not in use can help reduce evaporation and therefore decrease the need for constant refills. These small measures may seem insignificant, but they can add up to significant savings over time.
Regular filter cleaning is essential for maintaining the efficiency of your hot tub and reducing energy consumption. Dirty filters can restrict water flow, causing the hot tub’s heater and pump to work harder, which ultimately leads to higher energy usage.
By cleaning or replacing your hot tub filters regularly, you ensure that debris and contaminants are removed from the water efficiently, allowing the system to function optimally. This not only helps in keeping your hot tub running smoothly but also contributes to lower energy bills in the long run.
So, make sure you include routine filter cleaning as part of your hot tub maintenance routine to keep it operating at its best while minimising energy costs.
