Add in small steps with the pump running, wait, then retest before adding more. Never mix chemicals together, and always follow your product label, which wins over any calculator.

Bestway Vegas AirJet spec sheet

Heat and cost lines are formula-derived (102 F target, 50 F outside, average cover); treat them as floors for a well-covered tub.

How it compares

Class context: 35 inflatable tubs, median 240 gallons, median width 77 inches. This model holds 3 percent more water than the midpoint and measures the same width as it, giving 41 gallons per seat at full rating.

Filled weight and floor loading

In use you are supporting about 3,245 lb: the water alone is 2,060 lb, plus 6 people at 185 lb apiece. Spread over its footprint that is near 100 lb per square foot. Work out any tub on the filled weight calculator.

Running cost for this tub

The heater's job here is replacing about 6.3 kWh of lost heat daily under the stated assumptions (102 F water, 50 F air, average cover). Monthly that is close to $33 at $0.17/kWh, ranging $23 to $48. Model your own rate and climate on the running cost calculator.

Installation notes

Plan the pad before the purchase: 32.3 square feet of level, rated surface, a path wide enough for delivery, and a standard household outlet within safe reach. Drainage nearby helps when the 247 gallons eventually leave.
