How much electricity does a hot tub use?

While a pool is a more common source of enjoyment and comfort in the warmer months, there is another water-based activity that can be of interest to those who seek comfort in the colder months as well – we’re of course talking about the hot tub.

As technology has developed, it has become more and more common that people no longer need to go to spas to get their share of hot tubs, but they can also install one in their home to use at their pleasure.

Why does not everyone have a hot tub then? Well, it can get pricy. It’s considered to be an item not everyone can afford and therefore a symbol of status as well. But, if you are lucky enough to be considering buying one, keep in mind that the upfront costs may not be the only ones that are coming at you.

Besides the price of the purchase, there’s also installation but also the one that is recurring – the cost of electricity used to power your hot tub up.

How much money will the hot tub cost monthly?

When buying luxury items, the comfort has to come from somewhere, unfortunately, and hot tubs fit well into this category. In order to keep you warm and the water clean and circulating, hot tubs use electricity, which costs money.

Now, here’s the good news. Due to always developing improvements and due to the need of staying competitive on the market, the companies who develop and make hot tubs have made electricity requirements as low as possible. This goes in their favor as it’s much more likely you’d go for a hot tub that does not use too much electricity, as people like saving money in the long run. We all remember older appliances that were electricity hogs and sometimes even caused electricity outages if turned on at the same time. Luckily, those times are gone!

As for the slightly worse news, no matter how good the technology is, you’ll still have to pay something for the electricity. These rates vary by your place of residence, the price of utilities, and the brand of the hot tub, but can still be approximated.

Your hot tub will use electricity mainly to power the water heater. These heaters come in different voltages and vary from model to model, such as 240 or 120. If your heater is 240-volt, then you will use 6000 watts, whereas with a 120-volt heater you will use 1500 watts. The water circulation pumps also use around 1500 watts. Stronger heaters will heat better for the price of having more energy consumption.

Then, you just need to divide the wattage by 1000 to get kilowatts, multiply this number by the number of hours you’ll spend in the hot tub and you’re now only a step away from finding out how much you’ll be spending. This number of kilowatt-hours has to be multiplied by the rate of your utilities, and that’s it.

To put these terms into numbers and exemplify them for both cases: 

Let’s say your rate of electricity utilities is double the average at 0,20 cents per kilowatt-hour. If you get a hot tub with a 120-volt heater that uses 3000 watts or (divided by 1000) 3 kilowatts and will be using it for 20 days each month an hour daily, then monthly you will be paying 12 more dollars for your electricity bill.

If you get a stronger heater, you’ll be using 7,5 kilowatts per hour, and with the same usage of 20 days, one hour per day, you’ll be paying 30 more dollars for your electricity bill.

Now, considering we don’t know your local rate of electricity per kilowatt-hour, we’ve taken a very considerable and conservative approach and doubled what’s considered to be the average. Therefore, you can expect the actual number to be a bit lower, and considering how much usage you get from the hot tub, it probably won’t feel like too much of a waste.


Tips for saving money with a hot tub

While math can show you the estimate, it’s basically impossible to give exact numbers for this kind of usage, since hot tubs have a lot of variables.

Some of these variables include how big the actual tub is – of course, you’ll need a larger amount of electricity to heat up a larger amount of water – but this goes both ways. If you do not need a large tub, why not go for a 120-volt heater and save up?

The weather outside will also be of importance as if it’s warmer outside the water will get naturally warmer but you also probably will not feel the need to crank up the thermostat setting in order to be warm.

The brand quality comes into play as well as with everything else – good insulator properties can go a long way, especially when the hot tub is newer. 

Some of these costs are also up to you – will you be using the hot tub for long amounts of time at once or short soaks daily? Be mindful of having to heat up the water and all the heat basically going to waste if you’re going to stay for a short while only. 

Due to all these steps, hot tub buying can be a bit of a hassle. You need to consider multiple things, such as the costs of buying, costs of installation, where to install the hot tub itself, the costs of maintenance, and of course, as outlined above – the costs of running it monthly.

Therefore, we recommend thinking it through before buying, weighing all your options, and deciding based on your needs and capabilities. However, if you do decide to go for a tub, once it’s all done and plugged in, we’re sure you will be able to safely say you are content with your purchase, because how cool would it be to soak in hot water during those hellishly freezing colder months?
