In addition to using significantly more hot water than a traditional tub, a Jacuzzi also uses a pump motor, with a single horsepower motor as the most popular option. This type of motor uses 745 watts of electricity, and each hour the motor is used typically increases the energy bills by $0.08. Running an exhaust fan or turning on the lights in the bathroom can also increase the utility bill. For those who plan on running other appliances, such as a dishwasher or washing machine, at the same time as the Jacuzzi, an additional tankless water heater to supply the jetted tub may be needed. By examining the location of the jets in a specific Jacuzzi model, a homeowner can reduce the amount of time using the tub by pointing the jets exactly where they need to be. Spending less time in the Jacuzzi will allow homeowners to use less energy if they’re wanting to cut down on energy costs.
