I would like to install TRV's in my bedrooms, bathroom and kitchen.
However, if i isolate just one of my radiators my boiler starts to kettle within about 5 minutes. So in theory if i install TRV's and they close down then my boiler is likely to implode on itself. (maybe not that bad but...)
Any ideas as to why this might be the case?
System info:
Glow-worm Space Saver Mk 2, 40BR
C-Plan (Feed and Vent before the DHW MV)
Siemens Wireless room thermostat
Siemens cylinder stat
Siemens RWB29 controller/programmer
22MM feed and return pipes
15mm spurs to radiators upstairs and 8mm microbore to downstairs
7 Single bar radiators
No pumping over, no kettling usually, clean system - flushed annually and inhbitor added. System water exceptionally clean for the age of the system. F&E tank clear and no sludge.
THANKS!
