What is a Combi Boiler Diverter Valve?
If you have a combi boiler, you have a diverter valve. This is an essential component of the boiler that directs the flow of hot water to either your radiators or your taps and showers. Without a functioning diverter valve, your combi boiler won’t be able to provide hot water for your home.
A diverter valve is a mechanical device that opens or closes to direct hot water to the appropriate place. When you turn on a hot tap or shower, the diverter valve opens to direct the hot water to the tap or showerhead. When you turn off the tap or shower, the diverter valve closes to stop the flow of hot water.
The diverter valve is located within the boiler and is controlled by an actuator. The actuator is an electric motor that opens and closes the diverter valve. When you turn on a hot tap or shower, the actuator receives a signal from the boiler’s control panel to open the diverter valve. The actuator then turns the valve to direct the flow of hot water to the tap or showerhead.
Combi boilers are designed to provide hot water on demand, which means they don’t store hot water in a tank. Instead, they heat water as it’s needed. This is why a diverter valve is necessary in a combi boiler, as it allows the boiler to direct hot water to the appropriate place when it’s needed.
The diverter valve is a crucial component of a combi boiler that directs the flow of hot water to either your radiators or your taps and showers. It’s controlled by an electric actuator and is essential for providing hot water on demand in a combi boiler system.
