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.

 

Radiant Heating for the New Tank

So I’ve had a lot of experience helping people build float tanks… and I’ve come to the conclusion that radiant heating is the best way to heat your water, when possible. This isn’t some novel idea for people that know tanks, but for those who may be new to floating, here’s why:

1. Radiant can always be on to maintain the perfect temperature for LONG floats. (Over 1 hour) Whereas a non-radiant system will lose temp slightly over time, and will need to be turned on between floats to get back to temp.

2. No plumbing required! Less plumbing stuff… less chance for leaks.

3. It makes the water more consistent. Sometimes with heating systems that pump the water in, the water can have a cooler spot on the other end of the tank.

Simple, but great benefits.  NOW, here’s the catch with radiant heating and what we had to do to get around it with our new tank. Radiant Heaters are known to have slight electrical noises when they turn on and off. We had to make a custom designed heat pad that was bigger and silent. This adds some cost, but it makes the floating experience right, and that is mandatory.

In developing these new custom heat pads we were able to add a lot more benefit than planned. The foam made the tank softer on the feet, and because it compresses it made it safer and less slippery to step into. The foam also insulates the water from the ground which helps maintain temperature. This is very important because we went with a thin wall design. Thin walls make the tank more affordable, and lighter to ship.
