Owning a hot tub is one of life’s great luxuries — but it does come with running costs. One of the most common questions we hear from our customers is:
In this blog, we’ll answer that question — and share our top tips on how to run your hot tub more economically all year round.
Generally, no. Most modern hot tubs, like our Balboa-powered Impulse DP Hot Tub, are designed to be left on all the time.
Here’s why:
✅ Maintains water quality: When the hot tub is left on, the filtration system keeps the water clean and prevents bacteria growth.
✅ Avoids high reheating costs: Heating water from cold every time you want to use your hot tub costs significantly more than maintaining a stable temperature.
✅ Extends component life: Repeatedly powering the hot tub on and off can cause wear and tear on pumps and heaters.
In short: It is more efficient (and cheaper in the long run) to leave your hot tub running continuously — just lower the temperature slightly when not in use.
If you want to reduce running costs without compromising on enjoyment, here are some simple tips:
If you’re not planning to use your hot tub for a few days, reduce the temperature to around 30-32°C.
When you’re ready to use it again, it won’t take long to heat back up to your preferred setting (usually 37-39°C).
A well-insulated cover can reduce heat loss by up to 60%!
Check your cover regularly for wear, and replace it if it no longer fits snugly.

Clean filters keep your hot tub running efficiently and prevent your pumps from working harder than necessary.
Rinse filters weekly
Deep clean monthly
Replace every 12-18 months

Many hot tubs with Balboa control systems (like our Impulse DP) allow you to program filter cycles and economy modes.
Take advantage of these settings to reduce energy use during off-peak times.
Adding a floating thermal blanket under your hot tub cover further reduces evaporation and heat loss — a small investment that can make a big difference.
It is better to leave your hot tub on, but you can reduce the temperature when not in use.
Powering off completely should only be done if you’re draining it for winterisation or long periods of non-use.
With the right habits and accessories, you can run your hot tub economically all year round.

A: For most modern hot tubs, it is more economical to keep the hot tub running at a steady temperature rather than turning it off and reheating it each time. Regularly turning it off can actually increase running costs.
A: Use a high-quality insulated cover, lower your target water temperature slightly, run the hot tub during off-peak energy times, and ensure your hot tub is well maintained for maximum efficiency.
A: Yes — most hot tubs are designed to run continuously and maintain a set temperature. This keeps water quality consistent and avoids large heating spikes.
A: A temperature of 36–37°C is ideal for most users and helps to reduce energy consumption. Dropping the temperature slightly when the tub is not in use for a few days can also help save costs.
A: Running costs depend on the model, insulation quality, and your energy tariff. On average, a well-insulated hot tub costs between £1.50–£2.50 per day to run in the UK.
