The problem with BG powerflushing/cleansing etc whatever you want to call it

sales rep qoutes in for powerflush, this adds 6hours to job time.
Job time adds up to 18hours(for example), BG office bods decide to send 2 engineers , 9hours each, job to be completed in 1 day. 6hour flush gets split to 3 hours each per engineer. Engineers carry out 3 hour powerflush.

this I found out when investigating poorly flushed systems, whilst I was at BG

Love it.

I bet the same office bod would set 9 women to have a baby in a month...

sorry, i dont get it.

18 hours of what? flushing? total install?

each flush is entirely dependant on each individual system, both design and degree of "dirt".

two engineers to do what? flushing? i dont believe that. i dont see both blokes standing around watching dirty/clean water whilst there is install stuff to be done.

if the flush is done independantly of an install then i see no reason for it to be done improperly for any other reason other than incompetence or system difficulties. if its done on an install then it may be down to time constraints. only one of which is acceptable.

nickso and mickey. 'powerflush' is done properly as a powerflush should be. generally done in 8 hours but can be longuer depending on size of system cf/ov issues and magnaclean install.

the problem lies with powercleanse. its only got an allowance of 2 hours and thats really not sufficient. plus when we employ subbioes to do the install they just dont do it. been to to many customers with post install blockages and they've not seen the machine in use or were told it wasnt neccessary . there was one subbie who didnt even have the machine. this is why i tell all my customers to demand a direct labour install team and advise them about the powercleanse/powerflush differences before they even see the rep.

find out who is the BG contractor in your area and talk to them directly,save a few hundred pounds.

we both know thats not always true.

it was an example of the total job time totted up by the packs the rep puts into the qoutes. the number is of no importance. its an example.

I think the term your looking for is "should be"

if the flush is done independantly

I was purely referring to flushes done on installations not flushes(sorry if i didnt make this clear) done by the service side of the business. Which incidentally is usually done very well by some pretty damn good upgrade guys.

actually, reading it without the aid of ten pints of guinness it does make more sense than this morning.

Had another quote for the boiler replacement at the start of this article/message list.

Worcester Bosch 24 Kw CDI boiler installation (house is fairly large 4 bed with bathroom, en-suite, utility, kitchen sink and standard heating system)
Replace
Ten TRV's installed.
System flushed though- from the debate above though he is offering to do a basic job. Stating that the system is microbore piping and liable to blockages if too much disturbing of system. Sounds like he'll rinse and empty individual radiators.
No magnetic filter as BG suggested.

He did a proper survey- unlike BG saleman. He spotted unlagged pipes in the loft from a new shower installation- needs sorting. Also that the top-up hot water system tank in the loft is pretty stagnant- suggesting the system is sound as it has not needed to top-up for leaks.

£2100 all in

Another quote tomorrow from Worcester Bosch local guy.

Any comments on the above?

24cdi is a little underpowered considering you have approx 6 hot taps in the house, I would say 30kw minimum preferable 37 or 42 cdi. (providing you have an adequate water main)

 

[edeveuk]

Is the kw critical if I am running off a hot water tank for taps (conventional system)?

The more KW the better flow rates for hot water, 24kw is the entry level (think 1.0 vauxhall corsa) 42kw is a powerfull boiler (think bmw M3). The 24kw will run one hot tap slowly (9 litres/min) whereas 42kw will run 2 taps at a time (18 litres/minute).

 

[simond]

Worcester don't make a 24CDi, of any type.

They did only a few years ago

We have fitted those in the past, but one would hope that isn't the unit she has got a quote for!
