Basic concept of electric tanks

Electric tanks are devices designed to store and heat water through the use of electrical energy. Its main function is to provide domestic hot water for domestic, commercial or industrial use, guaranteeing a continuous and efficient supply. These tanks include in their structure an electrical system that allows the temperature of the water stored inside to be raised.

The design of the electric tanks includes a submerged or external electrical resistance that heats the water, as well as thermal insulation that minimizes heat loss. This type of equipment is characterized by its ease of installation and maintenance, being one of the most used solutions for the generation of hot water in places where centralized heating systems are not available.

Main components of an electric tank

An electric tank is made up of several essential elements for its operation. The tank or reservoir is the container where the water is stored; It is generally made of stainless steel or enameled steel to prevent corrosion and ensure durability. The thermal insulation that surrounds it, made of polyurethane or mineral wool, allows the water temperature to be preserved for long periods.

The electrical resistance, normally submerged in water, is the component that generates heat when fed by electric current. Along with the resistance, there is the thermostat, which regulates the temperature and prevents overheating of the water, guaranteeing safety and energy efficiency. In addition, the tank includes safety valves and connection systems for water inlet and outlet.

Capacity and dimensions

Electric tanks vary in capacity, from small models of 10 to 50 liters for individual use, to large tanks of several hundred liters for commercial or industrial applications. The selection of the appropriate capacity depends on the expected consumption and the number of users or consumption points connected to the system.
