Finding the order in which radiators heat up

[Pisces67]

In order to find out the order in which radiators in the house heat up, would be possible to time the point at which heat is detected through either the flow or ruturn pipe on the radiator?

Will report the results after completing the exercise.

Guys, did what you said and plinth now blowing hot air. Before I switch off should I be doing any more bleeding and how should I turn up the trvs gradually or all at once. Just conscience of all the oresdure on one plinth heater. Thank you

Just turn them all back on
You may well have to do same again when you drain down and refill.
Should be no need to bleed rads unless they are cool at top.

Thanks very much.

Regarding the final flush next week is it worth draining the system whilst the heating is on, with all valves (trvs and lockshields) fully open and toppingi up/maintain the water pressure to the boiler with the filling loop?

Hi can anyone confirm if the above would work?
