thermostat showing that heating is running but not heating up on evening setting?

hey ive hade this problem where the rads are only heating up at certain times, got the fan spinning on the therostat and the boiler is pumping central heating hot water but no heat coming through the rads? any thoughts would be much appritiated

Could be many many things I'd start by looking at diverter/zone valves.

thanks for your reply, yeah was worried it may be something like that. cant really touch that as only done level 2 plumbing and dont have much experince but was hoping there could be something i could do instead of getting the landlord to get someone out. plus its a learning oppertunity and need plenty of those!

Yea maybe a little involved for a beginner mate, may not even be that, it's just that's where I'd start.

yeah just dont wana screwing it up more, will just feel like a plank if its something simple but will see how it goes for a bit as it did come on earlier and heated all the rads

If its a gravity system its probably be airlocks
