Leaving a hot tub running all the time can be more cost-effective in certain circumstances, especially if the usage is frequent.

Here's why:

Energy Efficiency:

Modern hot tubs are designed to be energy efficient.

Once the water is heated to the desired temperature, maintaining that temperature typically requires less energy than heating it up from a cold state for each use.

Heating Costs:

The energy required to heat the water from cold to hot is generally more than the energy needed to maintain an already warm temperature.

This means that turning the hot tub off and on repeatedly can lead to higher energy expenditures.


Water Filtration and Circulation:

Many hot tubs are equipped with filtration and circulation systems that help keep the water clean and clear.

Running these systems continuously or on a timer can reduce the frequency of chemical treatments and water changes, which can save on maintenance costs and effort.

Climate: In colder climates or during winter, maintaining a constant temperature might consume more energy.

The specific energy efficiency of your hot tub, as well as its insulation quality, would be significant factors here.

Usage Frequency: If you use your hot tub frequently, it makes sense to leave it running.

However, if your usage is more sporadic, it might not be as cost-effective to keep it running continuously.


Electricity Rates: Consider your provider’s electricity rates and if there are peak and off-peak rates. You might be able to save costs by scheduling operations during off-peak times.

Features and Settings: Utilise energy-saving features, such as timers and eco modes, to optimise operations and reduce unnecessary energy use.


Ultimately, the decision varies based on your specific hot tub model, how often you use it, and personal preference for balancing convenience and energy costs.

It's a good idea to consult your hot tub's manual or your local dealer for the best practices regarding how leaving your hot tub running; effects energy use and ongoing maintenance.
