Heating Your Float Tank Water: Time and Cost

If you've ever considered buying a sensory deprivation tank for your home, one of the first thoughts that probably came to your mind is, "What does it cost to heat a float tank?"

Most people assume that keeping a float tank heated year-round is expensive, but we've tested it and the costs equal out to be more affordable than most might think. 

Let's dive deeper....

The ideal floating temp is 93.5 F, this is because even though your core temperature is 98.7 F, your skin isn't. Depending on your personal preference you may choose to keep your float tank water anywhere between 93-94 degrees F. 

How long does it take to heat up a float tank for the first time?

While we can't speak for every tank, we've experimented with the Zen Float Tent using our handy dandy electrical meter and these are the results we found: 

  • We started by dropping the tank to room temperature which turned out to be 61 degrees (water is colder than air at room temp), and then proceeded to heat it back up. 
  • It took 30 hours to raise the temp 30 degrees. We designed the heating system to be affordable, and always on.  This means it's not about speed, it's about efficiency.

How much does it cost to heat a float tank up and keep it heated?

  • It took 23.9 Kwh to raise the tank 30 degrees.  In Utah it's 8.8 cents per kilowatt.  Just over $2.10 to heat up. 

• Temperature maintenance has come in cheaper at about $1.20 a day in Utah. Keep in mind I we recommend keeping your home float room at about 78 F. If your tank is in a cooler room it will affect your daily cost.

PRO TIP: when the air temp is 78 F, it makes it so that the air being drawn into your tank while floating will feel like the water temperature. 

Another thing to remember is that when you first put in your salt it will drop the water temp SIGNIFICANTLY!  Don't worry, once all the salt is dissolved the water will return to a normal temperature, and then you can heat it up. 

So that's the skinny on heating costs and maintaining your float tank water temperature. If you have additional questions about floating or buying your own tank, make sure to check out our Ultimate Guide to Buying A Float Tank.
