I replaced 9 radiator valves today (gone from TRV to manual cos the TRVs were not working out).
2 of the radiators are taking forever to heat up. They are not the first or last rads on the circuit.
The flow pipe to the rads is searing hot, but the radiator lukewarm and the return pipe colder still. I therefore don't think it's a balancing issue.
I've had a look inside the valve and when fully open the close-stop seems to only be half way up I would have expected a bigger gap for water to flow through..
Is this enough or is this causing reduced flow into the radiators and therefore the delay?
I've attached a pic of the valve.
Cheers!
