In addition to lower upfront costs, inflatable tubs also boast higher energy efficiency than their fitted counterparts. This is important to the customer because it translates into a spa that costs less to operate. Inflatable models utilize just a single blower and pump, which makes them cost up to fifty percent less to run. These savings go even further when you consider the fact that an inflatable tub is typically only hooked up and running when you are wanting to use it, instead of connected around the clock like a fitted tub. Adding to the cost savings is the low maintenance requirements of inflatable hot tubs.
They don’t usually use real water jets, but instead use fans to “blow” the air around (also because of the 120 volt outlet), which causes them to cool down much faster than a regular hot tub. This cooling effect is only made worse by the fact that the materials they are made from lose heat much faster than the materials used on a regular hot tub. All in all, you aren’t likely to get more than 15 minutes to a half an hour of good heat out of an inflatable hot tub.
