Boiler runs for a short time then shuts down without heating the property adequately

Safety first: Ensure safe access around the boiler and controls.

Steps to check:

• Ensure enough radiators are open to dissipate the boiler's output.
• Check that TRVs in the room with the main thermostat are fully open.
• Verify that the room thermostat is not located near a heat source or in a draught.
• Adjust boiler flow temperature to a lower setting to reduce cycling.
• If short cycling persists, a heating engineer can review system design and control strategy.

Warning: Persistent short cycling reduces boiler life and efficiency; it should be addressed.
