Hi all, after a bit of advice please!
Worcester boiler with newish pump. When heating set to come on, quite often the upstairs rads warm up fine and the bottom ones dont. After a few resets of the boiler the rads come good. Boiler has just been serviced, all parameters normal. Pump is hot and feels like it is running. We have bled the downstairs/upstairs rads countless times.
Any ideas would be marvellous, thanks
