Yes, a geyser typically requires an isolator or an isolation switch as part of its installation. An isolator is a safety device that allows for the disconnection of power to the geyser for maintenance, servicing, or in case of emergencies. It serves as a means of safely isolating the geyser from the electrical supply to prevent electrical shocks or accidents during maintenance or repairs.
The isolator for a geyser is usually installed near the geyser unit and is easily accessible for users or service technicians. It allows for the disconnection of power to the geyser without having to shut off the main electrical supply to the entire building.
In addition to the isolator, electric geysers typically have a thermostat and an overheat safety cut-off switch to prevent overheating and ensure safe operation. Gas geysers may also have isolation valves or shut-off switches to control the flow of gas to the burner.
When installing or replacing a geyser, it’s essential to comply with local building codes and regulations regarding electrical safety and geyser installations. This may include requirements for the type and location of isolators, as well as other safety features such as pressure relief valves and temperature controls.
Overall, the presence of an isolator is an important safety measure for geyser installations, providing a means of safely disconnecting power to the unit when needed.
