How long will it take for the spa to reach desired temperature?
Initially, your hot tub will take 5 to 14 hours to warm to a suitable temperature. This will depend on your starting water temperature and the ambient air temperature. It is best to warm your hot tub with the cover on and leave the cover securely locked on the unit when you are not using it. It is far more efficient to bring your spa to desired temperature and maintain the temp as opposed to decreasing the temp between soaks and waiting (and paying) for the water to get to temp for each use.
