The electric shower: The Brazilian innovation that revolutionized the hot shower

Types of electric showers: The electric shower is one of the most common equipments in homes around the world. It is a hot water source for bathing and is extremely popular due to its ease of installation and use. As well as being an economical option for heating water.

Electric shower history

The electric shower was invented in 1927 by the Brazilian Francisco Canho, who developed a prototype in his own home. The idea came after Canho realized that many people in his hometown, São Carlos (SP), did not have access to hot water for bathing. Canho’s electric shower consisted of an electrical resistance embedded in a metal rod, which was immersed in water to heat it. He patented his invention in 1930 and soon began producing and selling his electric showers on a large scale. Over time, electric shower technology has improved, and nowadays it is a common item in houses and apartments throughout Brazil.

Electric shower operation

The operation of the electric shower is relatively simple. It consists of an electrical resistance that is triggered when water starts flowing through the shower head. When turned on, the cold water passes through a series of ducts that lead to the electrical resistance, where it is heated. Hot water then flows through the shower and is regulated by a temperature control valve. The amount of hot and cold water that is mixed can be adjusted by the user through the valve. Allowing him to regulate the temperature of the bath water according to his preference.

Types of electric showers

There are several types of electric showers available in the market. Some of the main ones are:

  • Ordinary electric shower: it is the simplest type of electric shower, and is usually found in low-cost houses and apartments. It has a simple electrical resistance that heats the water that passes through the showerhead;
  • Electric Shower with Temperature Control: It is a more advanced type of electric shower, which allows the user to adjust the water temperature more precisely;
  • Electric shower with solar energy heating: it is a type of electric shower that uses solar energy to heat the water. It is a more sustainable option than other types of electric showers, but it is generally more expensive.

Some of the main precautions include:

  • Proper installation: it is important that the electric shower is installed by a qualified professional and that he follows safety regulations. Improper installation can lead to the risk of electric shock and other problems;
  • Regular maintenance: the electric shower should be cleaned regularly to prevent the accumulation of dirt and limescale. In addition, it is important to regularly check the electrical resistance and other components for signs of wear;
  • Proper use: It is important not to exceed the power capacity of the shower, avoid using extension cords, and not use the shower with wet hands or barefoot;
  • Fire safety: it is important to have a fire extinguisher close to the bathroom and to avoid shower contact with flammable materials, such as curtains and towels.


In conclusion, the electric shower is a Brazilian invention that has revolutionized the way people shower across the country. Since its creation, it has been an affordable and practical hot spring for millions of people. Over time, electric shower technology has improved to include features like temperature control and solar heating. Making it an increasingly versatile and sustainable option. With proper care and maintenance, the electric shower will continue to be a reliable source of hot water for many generations to come.
