Type of boiler:
Conventional
Serial number:

Type of water cylinder:
None (combi

Type of pipework:
Copper

If microbore system, are twin entry radiator valves fitted? If so, are all
radiators completely warm when boiler fired? (i.e. are the radiator 'injector'
tubes still fitted correctly?)
If single pipe system, is there circulation (heat) to all radiators? Cold radiators
will need removal from system and individual flushing.
If elderly steel pipe work, is system sufficiently sound to power flush? (Or
would it be better to re-pipe?)
