Boiler heating outlet temp low

[Apollo71]

Hi,
Moved into property recently
Worcester Greenstar 24Ri (approx 2008) regular boiler
Radiator temps not exceeding 50C, and boiler outlet temp just above that. Condensate siphon was blocked but now cleared.
Grundfos pump and both motorised valves replaced last month
Temp dial to maximum.
Is the boiler on its last legs or is there anything else to check/replace to see me through the winter
Thanks

Trv fitted to radiators and pin free?

Does it heat the house adequately, and stop eventually on the roomstat? Unlikely, but if there is loads of rad area it's a possibility.
If it's not that, maybe the boiler stat is faulty, or perhaps the burner gas pressure is too low. Though I'm sure somebody will say neither is a DIY job.
