How Much Power Does a Hot Tub Use?

Some hot tub lovers just like the thought of soaking in a warm, stimulating environment.  They don’t really care how that occurs or how much it costs.  A different type of hot tub lover still enjoys being massaged by bubbling, warm water but is ever cognizant of what’s making that possible.  Especially the amount of energy that’s being consumed!  As they’re trying to soak away their tensions they may still be wondering, “How much power does a hot tub use?”  We’ve put together this article to help this second type of hot tub lover to be able to relax a little bit more.

How Much Power Does a Hot Tub Use?

Rather than ask how much power a hot tub uses, it’s probably better to ask what parts of the hot tub use the most power.  This will afford a better understanding of the hot tub components you’ll want to keep an eye on if you’re trying to minimize the amount of electricity you’re using.  By far, the biggest energy consuming component of the hot tub is the water heater.  It takes a significant amount of energy to raise the water temperature from what comes out of your garden hose to what feels comfortable in your hot tub.  After you’ve attained peak temperature, the water pump is the next biggest user of energy.  The pump ensures the circulation of the water through the filtration system and powers the water jets that are responsible for the massage that hot tubs are so well known for.  Other electrical components, such as optional lighting or a stereo system, are negligible power consumers compared to the heater and pump.

Hot Tub Model Variables

It’s important to understand that differences in hot tub models will also play a major role in how much power the hot tub uses.  It’s obvious that all else being the same, a larger hot tub will use more energy than a smaller hot tub.  Similarly, a hot tub that’s used frequently will use more power than a hot tub that’s rarely used.  However, the type of hot tub you buy will be the biggest factor influencing power usage.  What are known as plug and play hot tubs run off a 110 Volt power supply whereas hardwired models require a 220 Volt power supply.  Hardwired hot tubs will end up consuming more than twice the energy used by a plug and play hot tub.  So, what’s the advantage of the hardwired hot tub?  Because it’s able to draw a greater amount of power, it’s possible to run both the heater and the water pump at maximum capacity at the same time.  In a plug and play hot tub, if you max out the water pump, the water heater will turn off.  And although this isn’t a problem for short soaking sessions, it can become annoying if you’re hoping to use your hot tub for longer periods of time.

Reducing the Amount of Power, A Hot Tub Uses

If you’re concerned about your power usage and want to bring it down, conserving water heat is one of the best ways to do it.  Because the water heater is the biggest power consuming component, the less you have to rely on it, the less power you’ll use.

Hot Tub Covers

Hot tub covers are most often advertised as an accessory, but when it comes to power savings, they’re really a necessity.  By replacing the cover whenever the hot tub isn’t being used, you can reduce heat loss by 60% or more.  Combining it with a floating thermal blanket can conserve even more heat.  Make sure to invest in a well-insulated, good fitting hot tub cover.

Water Temperature Consistency

By maintaining the water at ready-to-use temperatures, you’ll actually use much less energy than turning off the heater after each use.  The amount of energy required to raise the temperature of cold water is noticeably more than that needed to maintain a constant temperature.  For this reason, it’s recommended to keep your water heater running constantly.
