The Bestway SaluSpa Miami Tub is the best option for a good, not soak in the middle of winter. The secret to this tub’s winter worthiness is a rapid water heater that brings the 177 gallons of water up to 104 F. The smaller two-to-four-person size of the tub also lets the heater work quickly when fighting against the outside cold air. An air pump is included for quick inflation.
Since it makes use outside air, the temperature may affect that of the water. The colder it is outside, the more noticeable the decrease in the water’s temperature. In worse cases, it is not a sudden drop but more of a gradual process as the bubble jets continue to run. We have yet to see an inflatable spa with heated bubble jets. Once that becomes available, you’ll definitely find it here first.
With this jet massage spa set, you can pamper yourself in relaxing heated water while being surrounded on all sides by soothing bubble jets. Needless to say, you shouldn’t normally expect this type of treatment from standard inflatable hot tubs, especially the ones in the low-end of the market as far as price goes. Also, this inflatable hot tub features easy-to-use controls designed to facilitate full-control over the tub’s many features with minimal effort.
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.
