Introduction

Welcome to our latest blog in which we delve deeper into the topic of “hot tubs”. In this blog we answer a number of questions such as "How does a hot tub work?". We also tell you more about the different parts of hot tubs and what kind of maintenance they need. Hot tubs are a way of relaxation for many, a luxurious way to escape from daily stress and enjoy warm, bubbling water. To best understand hot tubs, let us first briefly tell you a little bit about the 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 early versions known as wood-fired baths were used to stay warm during the harsh winters. These traditional baths were made of wood. These were then heated by stones heated in a fire and then placed in the water.

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

This evolution of the hot tub has led to modern variants that not only provide comfort, but also add a luxurious element to homes and wellness centers worldwide. Modern technologies in hot tubs now offer ease of use and a range of health benefits. It is not surprising that they are used by many for relaxation.

What parts does a hot tub consist of?

A hot tub is more than just a large bath; it is a carefully curated system designed for relaxation and comfort. In this section we discuss the main components that make up a hot tub.

  • The tub: This is the basic part of any hot tub, where the water sits. The tub can be made of different materials such as wood, acrylic, or reinforced plastic, depending on the type and style of the hot tub.
  • Heating element: An essential part 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 maintain heat in the hot tub. This part helps save energy and ensures that the bath stays warm for longer without having to constantly heat it. Wood types 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.
  • Cover: Although this part is not used while the hot tub is on, it is still an essential part. The lid ensures that the hot tub and the water it contains remain clean when not in use. This way you can 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 properly maintaining it, 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 different 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 exactly to the desired temperature with a thermostat.
  • Wood-fired heating: A wood-fired hot tub uses an external heater that is fired with wood. The water is heated by the heat given off by the heater, after which the warm 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 provides flexibility and efficiency, allowing users to choose or customize based on their preference and wood availability.

Each of these heating options has its own pros and cons, and the choice often depends on personal preference, resource availability, 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.

The operation of water purification & maintenance

In addition to heating, the operation 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 required to extend the life of your spa.

Filter systems

First of all 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. It is best to clean these filters regularly and over time you can also replace them 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 fight bacteria and algae. It is also important to monitor and adjust the pH of the water to prevent corrosion and limescale.
