Frequently Asked Questions (FAQs)
1. Can you insulate a hot tub?
Adding insulation to your hot tub provides a multitude of benefits to you and your guests. Insulating your hot tub will help to save you a lot of money in the long run because when heat is lost in the tub, it requires more energy to generate this hot water again, which then costs you more money.
2. How well insulated are hot tubs?
100% Full Foam Insulation is considered one of the best types of insulation in a Hot Tub. The foam supports the pipes and plumbing to prevent leaks and reduce the noise (as there are little or no vibrations).
3. Are there hot tubs that can also be cold?
With theCoolZone™ Hot Tub Cooling System, your Caldera or HotSpring Spas hot tub can both cool and warm spa water, something not possible with most hot tubs. It works much like an air conditioner, cooling spa water to as low as 60 degrees.
