Should I Leave My Hot Tub On All The Time?

By Adam


Many hot tub owners ask whether they should leave their hot tub switched on and running all the time. As an electrical appliance that uses energy and money, the logical answer to this would surely be no, right? 

However, you may be surprised to learn that the opposite is true. Contrary to popular belief, keeping your tub running 24/7 helps you save money on electricity, rather than racking up bigger bills – even if you don’t use it every day.

Leaving it on all the time also helps keep the water clean and sanitary and the plumbing working and free of dirt and blockages. Here are some of the reasons why you should be leaving your hot tub running, even when it’s not in use.

Should I Leave My Hot Tub Heater On all the Time?

Leaving your heater on all the time is beneficial for several reasons. Firstly it means you won’t have to wait for the water to heat up every time you want to use your hot tub. The average tub takes between 3 and 8 hours to heat up from scratch. 

Secondly, constantly switching the heater on and off between uses takes more energy than leaving it on all the time. Heating the water in the first place takes more power than keeping it at a steady temperature once it’s heated.

So leaving your hot tub heater on all the time not only saves you time but also money. Lowering the temperature a little will also help save money, so a good rule is to make it 5 degrees lower than it would be when in use (although this might differ depending on the climate where you live).

Making sure to keep it securely covered can also help keep the heat higher. Many hot tubs also come with an economy mode, making the heater cycle less throughout the day. This can help keep costs slightly down and keep the temperature slightly lower, which is excellent for the summer months.

Should I Leave My Hot Tub Pump On all the Time?

If you cover your hot tub when it’s not in use, you may not find it necessary to keep the pump running for 24 hours a day. However, the pump is vital for keeping the water in your tub heated and sanitized by keeping the water flowing across the heater and through the filters.

The constant movement of the water also stops it from going stagnant and breeding potentially dangerous and damaging algae and bacteria. You certainly don’t want to be getting into a tub if the pump hasn’t been on for at least 8 hours beforehand.

So it is recommended that the pump is left on at all times, especially if you don’t cover your tub.

Ensuring that any safety settings on your tub have been programmed to switch the pump off if needed should allow you to leave your tub with peace of mind and no worries about things going wrong or malfunctioning.

Should I Leave My Hot Tub Filter On all the Time?

Ensuring that your filtration system works at its peak efficiency is vital to keeping your hot tub clean and well maintained. Your filter needs to be given enough time to work properly and get its job done – filtering the water.

The cleaner your filter stays, the cleaner the water remains. And the cleaner the water is, the cleaner your filter stays, and the less you have to do to keep it in check.

It’s generally recommended that filters are kept running for around 12 hours a day or 24 hours a day if you use a circulation pump. This way, the filter will run at its very best and keep the water free of dirt and debris. 

Remember that your filter needs to be cleaned and unclogged regularly to keep it free of damaging blockages and always running at its very best – and changed once a year. Read your tub’s manual for specific instructions for the maintenance of your filter.
