Should You Leave an Inflatable Hot Tub On All the Time?

As parents and homeowners, we know what it’s like—life’s busy enough without standing around waiting for your hot tub to heat up. It’s tempting to just leave it running day and night, ready for a spontaneous dip. But is that really the smartest move?

The short answer: Yes, you can leave it on most of the time—but it depends on your usage, energy bills, and the good old British weather. Let’s break it down so you can decide what’s right for your home and your wallet.

The Short Answer: Why You Should Keep It Running

Maintaining Water Temperature and Cleanliness

Hot tubs don’t like sudden stop-start treatment. Once heated, it’s actually easier and cheaper to maintain a steady water temperature than to reheat from scratch every time. Keeping it running also helps the filtration system tick along, which means cleaner, safer water for you and your family.

The Benefits of a Consistent Schedule

Having your spa always ready is a luxury in itself. No more waiting hours for the water to warm up—you can simply jump in when you’ve got a spare 20 minutes. It also helps keep bacteria at bay, as water that’s constantly circulating stays fresher for longer.

When to Turn Off Your Inflatable Hot Tub

To Save Energy and Lower Your Electricity Bill

Energy prices in the UK aren’t exactly forgiving. If you’re not planning to use the tub for several days, switching it off can save a fair bit of money.

During Vacations or Long Periods of Non-Use

Going away for a week? Don’t waste electricity heating water no one’s using. Drain, clean, and cover your spa instead—it’ll be fresh and ready for action when you return.

During Extreme Weather Conditions

If the temperature’s plummeting or you’re expecting a storm, it’s best to switch off and store your tub properly. Inflatable materials and electronics don’t always mix well with extreme conditions.

The Cost of Leaving Your Hot Tub On

Calculating Your Electricity Usage

Running costs vary depending on your model and how warm you like your soak. On average, an inflatable hot tub in the UK can cost £1–£2 per day to run. Over a month, that adds up quickly.

Factors That Affect Running Costs

Insulated covers, ambient temperature, and even where you place your hot tub all play a role. A tub in a sheltered spot with a good cover will retain heat better, meaning the heater doesn’t need to work as hard.

How to Make Your Hot Tub More Energy-Efficient

Using an Insulated Cover

This is a no-brainer. A quality insulated cover traps heat, keeps debris out, and saves you money in the long run.

Choosing the Right Location

Pop your hot tub somewhere sheltered—near a wall, fence, or even under a pergola. Less wind means less heat loss.

Maintaining Filters and Water Quality

A clogged filter makes the pump work harder, costing you more energy. Clean or replace filters regularly, and keep the water balanced so the system runs smoothly.

Common Questions About Inflatable Hot Tub Maintenance

How Long Does an Inflatable Hot Tub Take to Heat Up?

The Initial Heat-Up Time

When you first fill your spa with cold tap water, expect to wait between 12–24 hours for it to reach the perfect temperature. That’s why many owners prefer keeping it on—it saves all that waiting around.

The Impact of Ambient Temperature

Winter in the UK? Your hot tub will take longer to heat, and it’ll use more electricity maintaining that warmth. Summer days, however, give you a bit of a break on the bills.

Is It Bad to Keep a Hot Tub On All the Time?

Potential Wear and Tear on Components

Running constantly does put more strain on the pump, heater, and liner. But with proper care—cleaning, water balancing, and timely filter changes—you’ll still get years of use from it.

The Importance of Regular Maintenance

Leaving it on doesn’t mean ignoring maintenance. Stick to a schedule: test the water, clean the filter, and give the tub a deep clean every few weeks. Treat it well, and it’ll keep rewarding you with bubbly relaxation whenever you fancy.

Final Thoughts

So, should you leave your inflatable hot tub on all the time? If you’re using it regularly, yes—it makes life easier and keeps the water cleaner. If not, turn it off when it’s sitting idle to save money and extend its lifespan.

It all comes down to balance. With the right care, a few smart energy-saving tricks, and a routine that fits your lifestyle, you’ll enjoy all the fun of your spa without any regrets when the electricity bill arrives.
