Frequently Asked Question

1. What is the energy efficiency of a hot tub?

Hot tubs do use a lot of energy since they require a lot of heating to keep the water hot. Energy efficiency will depend on the size of the hot tub, insulation, cover, and usage. 

As a general rule, you can expect an energy efficient hot tub to use between 40 to 80 kilowatt-hours per day. Using a hot tub cover, limiting run time, and maintaining proper water balance can help improve efficiency.

2. How often should I change the hot tub filter?

It is recommended to change your hot tub filter every 3 to 6 months depending on usage. Clogged or dirty filters reduce water circulation and filtration, lowering water quality and energy efficiency.

3. How often should I drain and refill the hot tub?

Every 3 to 6 months, it is a good idea to completely drain and refill your hot tub. This helps remove buildup of grime, minerals, and bacteria in the water.Some owners prefer to do a partial drain and refill, changing about 25-50% of the water every few months. But a complete drain and refill is best for sanitation.
