Hi everyone. Had a new system with Worcester 28i junior (combi) fitted a couple of weeks ago. System was flushed and filled with sentinel. 2 days after fitting, the Bathroom rad wasn't as warm as others. Bled radiator but the next day it was only lukewarm again. On saturday the pressure in boiler was up to 3.0 bar. Installer told us to drain radiator until pressure went down to just over 1.5 bar. Installer checked rads last night. All upstairs rads were only luke warm at top. Air and gas? came out of the rads. Installer said this could happen for a few months??? Bathroom rad luke warm at top again this morning. Going to phone installer, but wanted 2nd opinion as to what problem is - could there be grit in system?? Should we be expected to keep bleeding the radiators?? any thoughts appreciated. Many thanks.
