Insulate Inflatable Hot Tub: The Secret to Year-Round Relaxation

If you’re a fan of hot tubs, then you know that there’s nothing quite like a warm and bubbly soak after a long day.

But did you know that if your hot tub is not properly insulated, you could lose a significant amount of heat, which can impact the efficiency and cost of operating your tub? Plus, if you live in an area with harsh weather conditions and you fail to insulate your inflatable hot tub can also lead to damage.

In today’s post, we’ll show you the simple steps you can take to properly insulate your hot tub and enjoy a luxurious and efficient soak every time.

How To Insulate Inflatable Hot Tub

What Are The Benefits Of Insulating An Inflatable Hot Tub?

Insulating your inflatable hot tub may seem like a dull and unnecessary task, but it has several benefits that are worth considering. Let’s take a look at some of the benefits below:

  • Fewer vibrations and noise: Insulating the hot tub pad can reduce the noise and vibrations from the pump and heater.
  • Decreased heating time: When you insulate the hot tub, it can help retain the heat, and the tub will need less time to reheat the water in between uses.
  • Reduced heating costs: You can lower the consumption and costs of maintaining the desired temperature by insulating your tub.
  • Increased heat retention: After insulating the hot tub, heat loss through the ground and the walls of the tub decrease significantly, especially in cold weather.
  • Increase lifespan: Insulation can protect the base of the hot tub from potential damage from debris or sharp objects that could pierce the viny.

The Right Materials for Insulating

Choosing the right materials for insulating your inflatable hot tub can make a huge difference in how well you insulate it and how long it retains heat.

Foam insulation is a popular option, as you can easily cut it to fit the shape of your tub and restrict heat from escaping through the base. You can also easily purchase foam sheets or tiles from any hardware store.

Hot tub pads are another great option that can provide a strong barrier between the base of the tub and the cold ground surface.

Thermal covers and insulating foam boards are also effective in keeping heat in, and you can also add an inflatable insulator under the insulated cover to double the amount of insulation.

No matter which material you choose, proper insulation is the key to getting the most out of your inflatable hot tub.

Facts to Consider While Choosing the Insulating Material

Here are some facts that you need to consider while choosing the insulating material for your hot tub:

  • Protection from punctures and tears: The insulating material you will choose has to be durable and resistant to abrasions and punctures that could damage the inflatable hot tub.
  • Softness under the feet: The insulating material should also be soft and thick enough. This is essential to provide a comfortable feel for the swimmers’ feet.
  • Thermal insulation properties: The insulating material should have good thermal insulation properties. This insulation capability helps to prevent heat loss through the ground and the walls of the hot tub.
  • Temperature range: The insulating material should withstand high end of temperatures without compromising its performance or safety.

Some Effective Ways To Insulate An Inflatable Hot Tub

Let’s talk about some of the effective ways to insulate an inflatable hot tube below:

1. Ground Insulation 

  • Groundsheet: A groundsheet or tarpaulin is a thin layer of material that you can place between the hot tub and the ground. It is typically made from woven polyethylene, and it can create a barrier between the hot tub and the cold ground.
  • Hot Tub Pads: You can use a hot tub pad which is a thicker option compared to a groundsheet. It is usually made from high-density foam and provides improved insulation. You can provide better protection to the base of the hot tub and prevent damage from sharp objects on the ground.
  • Foam Sheets: Foam sheets are soft and thick, which makes them a great option for insulating an inflatable hot tub. They are available in different sizes and can be placed under the hot tub for insulation.

Ground insulation is essential for keeping your inflatable hot tub warm and comfortable. You can reduce heat loss and save money by choosing the right material to insulate the ground.

2. Insulating Around The Inflatable Hot Tub

Insulating around your inflatable hot tub is also important to keep the heat inside. You can use foam boards or insulation jackets for this task.

You can cut the foam boards to fit the shape of your hot tub and place them around the sides. On the other hand, with insulation jackets, you can have more coverage, and you can fit them easily on the sides of your tub.

You can also use a thermal blanket across the water under the cover. This will trap more steam, which will improve the insulating value of the cover. Remember to always put the cover back on right away when you’re not using the hot tub to keep heat inside.

You can extend the usage time, save energy costs, and ensure a more comfortable experience by properly insulating your inflatable hot tub.

3. Cover Insulation 

  • Keep it covered: You can use the thermal cover that comes with your inflatable hot tub. It should cover the whole hot tub and be inflated to create an air gap that will provide some insulation.
  • Add a thermal blanket: For even more insulation, you can lay a thermal blanket over the top of your hot tub before covering it with the thermal cover. The blanket will trap hot air and keep the water warmer for longer.
  • Double up with an inflatable insulator: Add an inflatable insulator under the thermal cover to double the insulation. This insulator fits under the cover and between the water to keep the heat in.
  • Consider a hot tub jacket: You can use a hot tub jacket or wrap to add an extra layer of insulation to the sides of your hot tub. It’s easy to fit and will help prevent heat loss.

By following these tips, you can effectively insulate your inflatable hot tub and keep the water warm for longer periods of time.

4. Insulate The Pump And The Pipes

Another important aspect of insulating your inflatable hot tub is to insulate the pump and pipes. This can help to prevent heat loss and maintain the temperature of the water.

There are a few simple steps that you can follow to insulate the pump and pipes effectively.

  • You can insulate the water hoses to prevent heat from escaping as the water travels to and from the pump. You can do this by wrapping the hoses with foam insulation or using pre-insulated hoses.
  • You can also insulate the water pump itself to prevent heat loss from the hot tub. This can be done by wrapping the pump with insulation or using a specifically designed pump cover.

By taking these simple steps, you can ensure that the warmth of the water will be maintained for longer periods while also reducing your energy costs.

Additional Tips To Keep The Hot Tub Warmer

In addition to insulating your inflatable hot tub, there are some other tips to keep the water warm for longer.

  1. You can keep the heater on or use a timer to maintain the water temperature constant.
  2. Keep the cover on the hot tub whenever it’s not in use, as this will prevent heat from escaping.
  3. You can place a thermal blanket over the water under the cover for additional insulation.
  4. Regularly clean and maintain your hot tub’s filter to ensure that the water is circulating efficiently, which can help to maintain the water temperature for longer periods.

By following these additional tips, you can keep your inflatable hot tub warm and relaxing for longer.
