How much power do hot tubs use? What factors affect how much energy they consume? What can you do to reduce the cost of running your hot tub? These are all questions that many first-time hot tub owners may have, and below, we’ll be providing you with the answers to those questions and more! Here’s what you need to know.
A Quick Intro to Hot Tub Electricity Usage
One of the first things to understand about hot tubs and electricity consumption is that a few factors can affect how much power your tub uses. These include the size of your hot tub, its features, how often you use it, and the cost of energy per kilowatt where you live. This means that there’s no one-size-fits-all answer to the question “how much power does a hot tub use?”
If you own a small hot tub that you only use occasionally, your electricity consumption will be much lower than if you have a large hot tub that you use daily. Similarly, if your hot tub has many features (like massaging jets, built-in speakers, etc.), it will likely use more power than a basic model. Finally, if your hot tub has excellent insulation, it will also use less power than one that doesn’t have good insulation. You can ask your
local hot tub dealer for more specific information on the different heating features available and how they affect power consumption.
To give you a general idea, you can refer to the kind of heater a hot tub has. This is the component that uses the most power, after all. If your hot tub has a 120-volt heater, it draws around 1,500 watts. If it’s a 240-volt heater, it uses about 6,000 watts. You can also use this formula for a more detailed estimate: (Heater wattage / 1000) x usage hours = kWh per month. Let’s apply this to an example to make it more straightforward. Say you have a hot tub with a 240-volt heater with a wattage of 7,500, and you use it for about 25 hours a month. This would mean your monthly electricity consumption would be: 7.5 x 25 = 187.50 kWh per month. To find out how much the increase in your power bill would be, we need to multiply the monthly consumption by the average kilowatt cost where you live. If the average kilowatt cost is 10 cents, your monthly power bill will increase by $18.75 for that particular month.
As mentioned, these are only estimates since there are so many factors that affect power consumption. There could be energy spikes during maintenance or when you first turn on the hot tub for the day that could increase your power usage.
An Energy-Efficient Hot Tub Is a Smart Investment
Now that you understand how hot tubs use electricity, you might be wondering if there’s anything you can do to reduce your power consumption. And the answer is yes! One of the best ways to save on energy costs is to invest in an energy-efficient hot tub. These models are designed to minimize power usage without sacrificing features or performance.
When shopping for a new hot tub, look for one with quality foam insulation that locks in heat. It allows the hot tub to maintain the optimal temperature without using much electricity. Another feature you’ll want to look for is an efficient filtration system. Ideally, it should be able to filter water quickly with low-amperage pumps. A hot tub with a high-quality cover is also a good idea since it will further reduce heat loss. A 3-4-inch hard tapered cover with insulated bumpers provides superb insulation, so the other hot tub components don’t have to use as much power to keep the water warm.
Now that you know more about how hot tubs use electricity, you can make a more informed decision about finding the right for you.
