What Does a Hot Tub Pump Do

Pumps in hot tubs and spas have two functions: They circulate water through the filter and heater and power the jets. Pump size varies from small 1/20 to 1/8 Hp circulation pumps to monster 2.5 or 3 Hp pumps used to power many jets. Hot tubs and spas use high-volume pumps.

Do you run hot tub pump all the time?

A dip in the spa can be a spontaneous event whenever the mood strikes. Since your hot tub pump circulates the warm water as well as the sanitizer, a general rule is to follow manufacturer recommendations or leave the pump on for a minimum of eight hours per day.

What temperature should I keep my hot tub when not in use?

We always recommend keeping the temperature at 38°C, not only will this keep you warm, it also helps to protect your hot tub as the heat generated stops your power pack from freezing over. Make sure to always keep the cover on when you’re not using it, so the heat doesn’t escape.
