Questions and answers
Hi, our shower is getting too hot. Won’t turn down & then turns cold. The reset button on boiler comes on. The pressure gauge is 2.5 bar. How do you turn pressure down? Is that causing very hot water? We have just bled radiator. Thanks
The provided context does not include specific instructions for reducing the pressure on a Worcester Greenstar 24i Junior boiler. However, to prevent the shower from getting too hot, you can try the following general steps:
1. Check the Central Heating Temperature: Reduce the central heating temperature on the boiler.
2. Adjust Thermostatic Radiator Valves: Turn down the thermostatic radiator valves if radiators are too hot.
3. Reduce Water Flow at the Tap: Lower the water flow rate at the shower tap to allow better temperature control.
4. Check the Programmer and Thermostat Settings: Ensure the room thermostat and programmer are correctly set.
If the issue persists, consult a heating engineer or refer to the boiler manual for further troubleshooting.
