Quick Fix: Check the ball valve and expansion cistern for blockages, and bleed the radiator to remove any air that could be causing issues.
Thereof, Why are my radiators still hot when heating is off?
The diverter goes into a ‘mid position’, which allows the hot water to flow to both the water tank and the radiators. When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off.
Also to know is, Why does my combi boiler keep firing up when heating is off? Pre-heating The timer and the thermostat should not affect the preheating process or a combi-boiler, however.

So your upstairs has a natural tendency to be warmer than lower levels. Hot roof. … If you don’t have an attic space to buffer the heat or your roof isn’t well insulated, this will increase the heat factor upstairs.
Also, How do you get airflow to the second floor?
Redirect airflow to the second floor If you have a basement, you can locate your HVAC system’s dampers on the ducts leading to the first floor and close them halfway down or more. This will push more airflow up to the second floor.
