halstead ace 7 yrs old (alledgedly! ) put in new thernistas both ch and dwh. Was ok ferra week but now locks out on ch after 1/2 hr and provides dhw for 2 minutes but only lukewarm even with dhw temp control up full. Come to think of it, bath has only ever filled to a reasonable temperature if mixer is on full hw and only partially opened.... teks an eternity to fill bath now we can only have very quick showers before enduring sum sorta eye popping cold water torture.
System was badly sludged up but as i was refurbishing the house only flushed thru rads individually and put sludge remover in last week... have drained down, put in inhibitor and bled all rads in sequence so no air locks.
Had corgi reg'd fella come out and put in new heat retardant lining in combustion chamber as old stuff had deteriorated and in places fallen off wall of chamber and was obstructing burners/jets.... mate suggested summat about diverter valve????
ANY SUGGESTIONS???????
