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

Hot tubs are for many a way of relaxation, a luxurious way to escape from the daily stress and enjoy warm, bubbling water. To best understand hot tubs, we will first tell you a little bit about their history.

History of the hot tub

The hot tub as we know it has an interesting history that dates back to different cultures and eras. Originally, the first forms of the hot tub emerged in the cold climates of Scandinavia, where the early versions, known as wood-fired baths, were used to keep warm during the harsh winters. These traditional baths were made of wood. These were then heated by stones that were 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 the onsen, or natural hot spring, became popular for therapeutic purposes. In America, the hot tub evolved from a simple wooden barrel to the modern jetted tub and electric heating system we know today.

This evolution of the hot tub has led to the modern versions that not only offer comfort but also add a touch of luxury to homes and spas worldwide. The modern technologies in hot tubs now offer ease of use and a range of health benefits. It is therefore no wonder that they are used by many for relaxation.

What parts does a hot tub consist of?

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

• The shell: This is the base part of any hot tub, where the water sits. The shell can be made of different 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 different types of heating systems, including electric heaters, wood stoves, or gas-fired systems.

• Insulation: Good insulation is crucial to retaining heat in the hot tub. This component helps save energy and keeps the tub warmer for longer without having to heat it continuously. Woods such as 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 is not used while the hot tub is on, it is still an indispensable part. The lid ensures that the hot tub and the water it contains remain 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 an important 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 will tell you more about heating the hot tub.

How does heating a hot tub work?

A hot tub can be heated in a number of 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 set to the exact desired temperature with a thermostat.

• Wood-fired heating: A wood-fired hot tub uses an external heater that is fueled by wood. The water is heated by the heat given off by the heater, after which the hot water 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 atmosphere.

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

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

How water purification and maintenance works

In addition to heating, the functioning of water purification and other maintenance is also important. Good water quality and regular maintenance are essential for optimal enjoyment of your hot tub. In this part of our blog, we explain how to keep the water in your hot tub clean and clear, and what maintenance is needed to extend the life of your spa.

Filter systems

First of all, there 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 can be replaced over time to improve their effectiveness.

Chemical treatment

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