Cant answer all your questions yet as I have just turned off the system for it to go cold so I can check the flows. But I can tell you there are drayton TRV4's fitted to the rads..i put them on as I decorated...the only ones that don't have em are the bathroom ones...(2 rads). The pump is...

Well I decided to do a bit of investigation.....I turned off the heating last night and had just the hot water on . Fine for the last 12 hrs.....5 showers and a bath......Yeah I am clean.... Now I have turned off all the rads....bar two and turned on the CH.and turned off the HW it is...

Well I replaced the PCB...and all was working fine till about two days ago...see new post.....Boiler bangin.

well the tank is fine and full..... And I suppose the only way of finding out if the pump is sticking is to change it and see if it fixes the problem..... one thing i have noticed is that the feed to the system is also the vent.......ie pipe coming out of tank....t piece one side going to...

Thanks for giving me this advise first of all.........appreciated. Yeah took the middle cover off the pump and it is spinning when selected too. But is it supposed to leak from here?.........i wondered if it was or wasnt...cos a seal might have gone...... But it is running....smoothly too.

Yeah it does not matter where the dial is on the boiler, it will do it in any setting. yes it is an old board one green one red LED Pt # 407750 Is the new one different then?......(we digress)

Right. I have a Potterton Suprima 60...Lucky me. On fire up its seems to run fine but it just keeps on running untill the water in the system boils and comes out the over flow. Obviously loads of banging as well as the air in the system expands. I have replaced the thermister and it worked for...
