I have been having problems with a few radiators in the house,
which
do not warm up at all, when the heating is switched on. Having
read
about all the symptoms of sludge build up, it looks like power
flushing is the way to go, to rid the system of it.

I am intending to try it myself, so any help on it will be
appreciated. I need to clarify a few points about the process;

1. I have a Potterton Puma combi-boiler. Do I need to check the
type
of Inhibitor I need to use, before I put it into the system?
2. Do I need to connect the power flush kit, across each radiator
and
repeat the process for all of them?
3. I have read conflicting theories about the sequence of events
for
power flushing the system, i.e., drain the system first, refill,
add
inhibitor .....etc. Can someone please tell me the sequence in
which I
need to carry out the whole process?

I figured I needed to do this myself........as BG quoted me £800
to do
the whole house, which I thought was bit off a rip off,
considering
that you could hire the equipment from HSS for £75.00 for a
weekend +
£20.00 for the chemicals.

Any help on this will be appreciated.

Sign up to BG's service contract that they keep pushing - then tell
them
to
sort out the rads that don't get hot.

No doubt their pre-contract check will find this and refuse the
contract
based on that. Or only offer it after fixing.

No not so. When I put one of my flats on the BG scheme they were
prepared to
take on an existing fault and fix it in the standard price so long as I
signed up for a year for the full service - money well spent as the
tenant
is a pain !

Just to let you know, that I do have BG 3* contract, and had an
engineer come round to balance the system, but has made no difference.
Also clearing sludge is not covered by this contract(SURPRISE!!!).
However, taking your advice, I will try and balance the system myself,
before I proceed with manually flushing the radiators. If this does
not work, what do you suggest I do?

Incidentally, what is covered by the contract? (or what other exlcusions
are there?)
