HELP ! I've been in this house now for 1.5 years and have had a
nightmare with this CH system (only 6 years old)
It's a conventional boiler with CH and HW loops, open vented. I have 2
issues that are kind of related really so here we go.
1. When we moved in the first thing I noticed was that the TRVs were
sometimes on the flow and sometimes on the return. Is this wrong, if
so how serious an issue is it for the performance of the system ??? Is
there grounds for quizzing/pushing the installer ???
2. 2 of the radiators have been really problematic, kitchen and spare
bedroom. They hardly get warm despite me having many attempts at
correctly balancing the rads. All rads upstairs close to the pump are
turned down almost fully and still heat up really quick. I've been
through most of the posts and FAQs on this too. When I switch all
other rads off and just keep these two on ONLY the spare bedroom rad
responds and really hots up. This has a TRV on the return (as the lsv
side gets hot first ???). The kitchen one only just warms a little
along the top and the return stays cold and has a TRV on it. I have
had both rads off the wall, flushed them (all clear) and both flow and
returns are clear of blockages. The kitchen rad fails to heat even
when its the ONLY one switched on. Mind blowing !!! The kitchen rad is
just new last week, flow and return seem blockage free and the flow
freely once the lsv and trv are opened without rad.
Is there anything here that jumps out to you guys as to what could be
happening here because
I'm going mad with this.
Much appreciate any help here.
