Valves red hot. Radiators cool. Trv stuck. Hit it harder. You will see immediate result, unless not hitting it hard enough. Hit it harder.
No zone valves in the system and certain the HIVE system is calling for heat as thermostat set well above room temps in my tests (as I type I wonder if the boiler is reaching the set water temp (70 odd degrees) and cutting out - but again, doesnt explain why his brothers radiator 8ft away in another bedroom shoots up to 65 degrees in no time yet problem rad is still 50 degrees after a couple of hours normally - so I do think the system is calling for heat constantly
Can I just ask one more favour - Im seeing 1.25 bar pressure rise from cold to hot and have a cold pressure of 1bar, hot goes just over 2bar after 3 1/2 hours tonight. Does this indicate I should check/re-pressurise the expansion vessel or is +1bar from heating acceptable? The vokera 35h EV should be at 1bar.
If I test the EV, I understand the system should be drained of water (so diaphragm has air on both sides) is this correct?
Just trying to get as many jobs done at one time if the system does need draining of all water (not sure if it does for these two jobs -TRV replacement and EV checking).
