As a first-time hot tub owner, you might have many questions. In this blog, we’re answering the question of what temperature to leave your hot tub on overnight.

What temperature should my hot tub be when in use?

When using a hot tub, you must be careful with the temperature you have it set to. Read our blog on hot tub safety to ensure that you and your guests are safe. If you’re wondering why is the hot tub temperature important? Then the answer is, for safety reasons!

You should ensure that your hot tub does not exceed a temperature of 40 degrees Celsius. If you use your hot tub at a warmer temperature than this, you may run the risk of feeling unwell. Keep an eye on your hot tub temperature and your body temperature when using a hot tub, especially in warmer weather.

You should also be wary of any underlying health conditions when using a hot tub. Speak to a medical professional before using a spa, regardless of the specific temperature you choose to have it set to. Pregnant women should also avoid using hot tubs due to various potential health risks.

In addition to not having your hot tub too hot, you need to ensure that you have used the correct chemicals to balance the water properly. Check out our hot tub cleaning guide for all you need to know. You must service your hot tub regularly. You can also visit our online shop to purchase all of your essential hot tub products and accessories.

Should I leave my hot tub on overnight?

Many hot tub owners ask this question, and the answer is yes, you should. If you turn off your hot tub, then the water can become unsafe as it is not being filtered correctly.

If you do decide to turn off your spa, you must ensure that it is completely emptied so that no water remains in the pipes. Letting water sit for too long can damage your hot tub, which is not what you want.

Leaving your spa on is much safer. It means you don’t need to wait for the hot tub to heat up from nothing, saving you time and allowing you to start enjoying your spa as soon as possible. Read our blog on how long a hot tub takes to heat up. Leaving the spa on can also save you money, as your hot tub will not require as much energy to heat up.

If you want to decrease your hot tub’s heat-up time and electricity bills, why not consider adding a heat pump? Check out our wide range of heat pumps and read our blog on how much you can save with one. Heat pumps take in the ambient air temperature and heat it, leading to warmer hot tub water.

What temperature should I leave my hot tub on overnight?

If you know you’ll be using your hot tub over the next few days, then it’s usually recommended that you leave the spa at its regular temperature or set it to a slightly lower temperature.

Some people find that both of these options end up costing the same amount due to the spa’s high-quality insulation. If you decide to turn the spa temperature down, you might want to consider setting it in the mid to high 20s. The spa will take less time to heat up from this temperature.

Those leaving the spa at its regular in-use temperature may not notice that it costs more due to the spa’s insulating properties. This is known as keeping the spa at a constant temperature. Here are some ways to improve your spa insulation.

Purchase a quality spa

We’d always recommend that you purchase a quality spa, as the highest quality spas use the best insulation methods. For example, Master Spas™ utilises Icynene Foam Insulation, which expands inside the body of your spa, eliminating any cold spots.

Hot tub covers

All of our luxury hot tubs come with their own insulated cover, which should be placed over the spa lid whenever it is not in use. This helps to keep heat inside the spa and reduces the risk of debris or dirt getting into the water and filters.

Invest in a good-quality pump

Your hot tub’s water pump is responsible for moving the water around your spa, which plays an important role in keeping the water warm and clean. All of our spas are equipped with quality pumps to ensure that water can flow effectively.

You could also consider a hot tub heater, although heat pumps may be more appropriate for those wanting to be more energy efficient.

What are the best spa temperatures in summer?

Summer is a fantastic time to use your spa, as it means enjoying the great outdoors, hopefully with the sun beaming down! You should ensure that you take safety precautions in summer such as wearing suncream and potentially a sun hat. You should also ensure that you remain hydrated before, during and after using your spa in summer.

It’s recommended that you do not exceed a hot water temperature of 37-38 degrees Celsius in summer – this is the ideal hot tub temperature for this time of year. If it’s warm, it may still be comfortable to set the temperature a few degrees lower than this. Lowering your hot tub temperature can also help to reduce your hot tub running costs, but you’ll still be relaxing in warm water.

What’s a safe hot tub temperature in winter?

When it comes to winter, it can be tempting to turn up the heat a little more, but you do need to be careful of this. You should ensure that your hot tub remains below the maximum temperature of 40 degrees Celsius. This slight water temperature increase should help to take the chill away during those winter hot tub sessions, leaving you with the perfect hot tub temperature.

Using a hot tub in winter can be just as much fun as the summer. Just make sure that you have a towel nearby, and perhaps consider wearing a woolly hat while using the spa. This can help you to stay warm when it’s cold outside.

Remember that if you ever plan on not using your hot tub for a while, you must empty it completely and ensure that no water is left inside. Failing to empty the spa completely can lead to damage.
