Hi all
I'm new here so thanks in advance, I have an old Netaheat boiler set up (gravity fed) which failed to fire up for central heating last week, I have set the three way diverted valve to manual and have been using the "call for hot water" to heat the radiators (once its been on for half hour and nice and hot I do get nice hot water pouring into the expansion tank) so want to get this resolved asap, tonight I bought a full Honeywell v4073 and swapped out the head, however, this hasn't remedied the issue, the spindle still seems loose enough (can turn by hand) my thermostat (old wired type - non digital) is set to full and clicks in and out & the controller (old lifestyle Lp722) led come on when I advance for central heating with nothing happening elsewhere.
I have removed the new valve head from the brass valve itself to see what happens when I switch from call for hot water/call for both/call for central heating only and it does nothing.
It is most likely that
A. The new valve head is duff
B. The controller is duff
C. The thermostat is knackered
D. Other
It has all previously worked well so I doubt a wiring fault, I'm skint and a well experience diy'er & would never mess with gas FYI, just after a few pointers to narrow the fault until I hav to go cap in hand to relatives for plumber money!
Thanks
Dan
