Just had a quote for a new boiler. Existing rads, pipework, pump, valve,
electrics etc. I'm draining & flushing the system & running the condensate
waste. Going in the same place as the existing one, some brick work needed.
Running 3 double rads & 5 singles. 3 bed semi.
Guy wants £1,236 inc VAT & a Magnaclean filter.
Doesn't specify the make of boiler.
Seems a bit OTT to me? Is it about right?
Since there's a cost variation in suitable boilers from about £400 to
£1500, it's a bit difficult to say until you know what it is.
Is he including the Magnaclean filter or expecting you to do that bit?
At any rate, it ought not to be necessary as long as you do a proper
flushing job. A strainer in front of the boiler ought to be enough to
protect the boiler.

If you can guarantee that the existing system is clean. When I replaced
my mum's boiler I thought I did a reasonable job of flushing - connected
mains one end, drain the other and opened up each rad in turn, but was
repeatedly having to clear the Y strainer - the system was cold and hot
flushed after the boiler swap. Swapped the strainer for a MagnaClean and
it's been trouble free ever since: any debris gets taken out without
impeding the flow.
Don't buy a pig in a poke.
Insist on knowing what boiler is being offered and then do a bit of
research and find a boiler that you want at a price that suits you. When
you know the price of the boiler you'll be able to compare his labour
charge with your own to decide if it's reasonable.
Seems like it could be quite cheap... it cost me not far off that to
fit my own without charging for labour. So I would guess we are talking
about a bottom of the range Biasi or similar...
I would have thought starting by specifying the boiler you want would be
the way forward. See what quote you get then.
If it is a like for like swap (e.g. combi replacing combi etc) then that
sounds like about three days work for one man with proper flushing and
making good etc. So if the quote comes to more than the price of the
boiler plus 3x your day rate, you know who is fitting it as well ;-)
Its a conventional replaced by a condensing - not that I want one
specifically, but thats what the Guvmint says I have to have. I'm flushing,
they are making good.
I don't have a problem fitting my own boiler, done it twice before, but
although I'm very competent I'm not CORGI. Wouldn't this be a problem?
Are you serious - THREE DAYS? I had a backboiler/gas fire removed and a new
boiler fitted, re-routed gas pipe and water pipes, thermostats etc. It took
*ONE* day and the system was also flushed out completely. It was a
conversion from old to new heating system.
If a straight changeover takes three days then the fitter is either
stringing it out for extra money, ripping the customer off or crap.
In terms of the work needing to be done that is pretty much like for
like (apart from the drain obviously) - its not the same as having to
rip out cylinders etc, and do loads of other re-plumbing in the process
for example. To do the latter (going from vented storage to combi) took
me about 4 days all in.
Not really. The only legal requirement is the competent bit.
How many people working?
You might get it done in two man days perhaps if you hit no snags, but I
would say that doing it much quicker is pushing it or skimping something
Also appreciate I was estimating what it would probably take Dave to DIH
given that while competent on the individual jobs, he does not routinely
fit boilers for a living, and hence may need a little extra time.
To do mine, working methodically and carefully took about four days
(albeit for a more complex job than just a swap out).
The job list was:
Tie up ballcock in CH header
Drain system - ensure 3 port valve is in centre pos to ensure heating
loop is drained.
Cut CH feed and return in loft and loop back. Include gate valve on a
tee in loop
Cap pipe ends to prevent seepage
Take static gas pressure reading and ensure loss is zero
Turn off gas
Pull fuse from boiler FCU
Disconnect boiler electrics and remove programmer
Disconnect CH feed and return
Disconnect gas feed
Remove from wall
Remove old flue
fill old flue hole with bricks and mortar
Using template mark out positions
Core bore new flue exit
Fit boiler mounting frame (remove tiles as required)
Connect CH feed and return
Remove existing gas feed pipe to under worktop
Cut new hole through worktop for DHW feed and return, 22mm gas, condensate
Install 22mm gas feed from existing ¾" pipe
Turn off water
Cut in new DHW feed and return and connect with service valves
Install filling loop
Mount boiler on tray
Install new flue
Install condensate drain
Tie off cistern ballcock
Drain remains of hot water
Disconnect hot water output from cylinder and cap off
Disconnect input mains water from cistern and CH header tank
Disconnect cold shower feed from cistern and connect to rising main
Remove bath panel and identify CH stat wire - join to existing down wire
and disconnect from remainder. (Leave remainder available for pulling
through new wires later!)
Connect boiler electrics and stat
Carry out any pre checks as per install manual
Carry out gas soundness test
Purge gas meter and pipework
Commission boiler as per manual
Flush as required
Treat with corrosion inhibitor
Remove tanks etc. and cylinder from loft.
