Some questions about balancing central heating

[Ermintrude]

Stick boiler on the e setting and that's it. If it's open vent check all your pipe work is lagged and your headder well insulated.

Is the pump wired directly to the boiler? If not ask your installer to come and correct this as it will immediately invalidate your warranty. Take it you don't have an Eco pump? I would look at a filter, smart start stat and check your cylinder stat isn't set above 70c .

OK so two things found. Firstly the flow rate WAS too high. I slowed the pump back to setting 2 and I can now open the radiator lock shields more and still achieve a decent differential. I settled for 10-15 deg c as each lap around the house gave slightly different readings as I adjusted each rad in turn.
Another thing I noticed was that I was getting hot water with just the heating on. I hadn't noticed this before because because the programmer was set to heat water. I tried the hot water without heating and found the radiators heating up. I found the cause of this to be a faulty diverter valve. I am wondering if this could be the cause of high bills. Boiler heating both systems when only 1 was needed?
All in all I now seem to have a nicely working heating system and its much quieter too. No more slurping and gurgling noises.

Thanks for all the help!
