How does a hot tub work? A simple and comprehensive explanation

For many, hot tubs are a way of relaxation, a luxurious escape from daily stress and the pleasure of enjoying warm, bubbling water. To best understand hot tubs, we'll first briefly explain their history.

History of the hot tub

The hot tub as we know it has a fascinating history spanning various cultures and eras. Originally, the first forms of the hot tub emerged in the cold climates of Scandinavia, where early versions, known as wood-fired baths, were used to stay warm during harsh winters. These traditional baths were made of wood, heated by stones heated in a fire and then placed in the water.

As time progressed, the concept of the hot tub spread around the world, with each culture putting its own spin on the basic design. In Japan, for example, the concept of onsens, or natural hot springs, became popular for therapeutic purposes. In America, the hot tub transformed from a simple wooden barrel into the modern bath with jets and electric heating systems we know today.

This evolution of the hot tub has led to modern versions that not only offer comfort but also add a touch of luxury to homes and wellness centers worldwide. Modern hot tub technologies now offer ease of use and a range of health benefits. It's no wonder they're used by so many for relaxation.

What parts does a hot tub consist of?

A hot tub is more than just a large bath; it's a carefully constructed system designed for relaxation and comfort. In this section, we'll discuss the key components that make up a hot tub.

• The shell: This is the base of every hot tub, where the water sits. The shell can be made of various materials, such as wood, acrylic, or reinforced plastic, depending on the type and style of hot tub.

• Heating element: An essential component that heats the water and keeps it at the desired temperature. There are various types of heating systems, including electric heaters, wood stoves, and gas-fired systems.

• Insulation: Good insulation is crucial for retaining heat in the hot tub. This helps save energy and keeps the tub warmer for longer without having to constantly heat it. Woods like red cedar are known for their excellent insulation properties.

• Filter system: This ensures the cleaning and purification of the water. An effective filter system keeps the water clear and free of dirt and bacteria.

• Lid: Although this part isn't used while the hot tub is in use, it's still an essential part. The lid keeps the hot tub and its water clean when not in use. This allows you to use the hot tub immediately without having to clean it first.

Each of these components plays a vital role in the functionality and enjoyment of your hot tub. By maintaining them properly, you can enjoy your investment for years to come. In the next chapter, we'll tell you more about heating your hot tub.

How does heating a hot tub work?

A hot tub can be heated in various ways, depending on the type and model you choose. The most common heating systems are electric, wood-fired, and sometimes a combination of both, known as hybrid systems.

• Electric heating: These systems use electric heating elements to heat the water. They are easy to use and can be adjusted to the desired temperature with a thermostat.

• Wood-fired heating: A wood-fired hot tub uses an external heater fueled by wood. The water is heated by the heat from the heater, which then circulates between the heater and the hot tub. This type of heating offers an authentic experience and is often appreciated for its natural warmth and ambiance.

• Hybrid systems: These systems combine electric heating with a wood-burning stove. This offers flexibility and efficiency, allowing users to choose or adjust based on their preferences and wood availability.

Each of these heating options has its own advantages and disadvantages, and the choice often depends on personal preference, availability of resources, and how often you plan to use your hot tub. Now, we'll tell you more about water purification and other maintenance involved with a hot tub.

The operation of water purification & maintenance

In this part of our blog, we explain how to keep the water in your hot tub clean and clear, and what maintenance is necessary to extend the life of your spa.

Filter systems

First and foremost are the filter systems. Most hot tubs are equipped with one or more filters that help remove dirt, oil, and other contaminants from the water. These filters are best cleaned regularly, and you can also replace them over time to improve their effectiveness.

Chemical treatment

To keep the water safe and pleasant, it's important to maintain the correct chemical balance. This includes adding disinfectants like chlorine or bromine, which help combat bacteria and algae. It's also important to monitor and adjust the water's pH to prevent corrosion and limescale buildup.
