Boiler Switches

What is a boiler isolator switch?

A boiler isolator switch, often referred to simply as a boiler switch or boiler disconnect switch, is a crucial component in heating systems, particularly those using boilers as their heat source. This switch serves as a means of controlling the electrical power supply to the boiler, allowing homeowners, technicians, and maintenance personnel to isolate the boiler from the electrical circuit for various purposes.

One of the primary functions of a boiler isolator switch is safety. In case of a boiler malfunction or the need for maintenance or repairs, turning off the isolator switch ensures that the boiler is completely disconnected from the power source, preventing accidental startup and potential hazards.

Furthermore, a boiler isolator switch is also used for routine servicing and inspections, as it provides an easily accessible point to cut off electricity to the boiler, making it safer to work on. It simplifies the process of isolating the boiler without having to shut down the entire electrical system in a property.

Boiler isolator switches are typically located near the boiler unit, ensuring quick and convenient access. Switched FCUs and double pole 20A switches can be used. Proper utilization of the boiler isolator switch is essential for maintaining safety and efficiency in heating systems.
