I am about to have a new Combi fitted (Worcester Bosch 30cdi). The installer
and I cannot see the existing gas pipe to the current Worcester Highflow
Heatslave so are not sure if it is 22mm or smaller. (obviously we will see
it when the boiler is removed)

A neighbour in the same type of house found when his Heatslave was replaced
that the pipe was only 15mm and had to have a new (ugly external) 22 pipe
run installed. This neighbour never had much success with his Heatslave -
but mine has always performed well and has been inspected every year by B
Gas.

I told the installer I was concerned that the pipe could be 15mm so he
offered to perform some sort of drop check. He took a reading at the meter
with a manometer with the gas cooker and boiler running - he then repeated
the test at the boiler and phoned Worcester Bosch. They confirmed that the
pressure was acceptable. I think the drop was 2 milli-bar. (from 21 down to
19)

I realise there is some risk and uncertainly and that I may have to run a
new 22mm pipe - but what do you think. Does the 'evidence' point to the
hidden pipe being 22mm - or is this irrelevant because the pressure is okay?

Do you think the installers approach is reasonable?

What do you want, a magic answer?

If the installer has taken readings which WB consider to be acceptable,
then either go with professional advice or don't

Nobody else can make your decision for you

If the pressure at the boiler, with all gas appliances running, is
adequate according to the manufacturer, then I don't see that it matters
what size the feed pipe is. I would be more interested in whether it is
in good condition.

Is the capacity of the new boiler the same as that of the existing boiler?

If not, the test is invalid because if the new boiler consumes gas at a
faster rate, the pressure drop will be higher - and the pressure at the
boiler may or may not be within acceptable limits.

Thanks for posing that question -

The old boiler gives 2.3 cuM/h at 10 mins after lighting (7 milli bar
pressure setting at burner)

The proposed one requires 3.4 cuM/h 10 mins after lighting.

I suppose - I need to expect the worse and expect to have to run another
pipe.

Any further info will be appreciated - I like to understand what the issues
are.

I presume so. I wasn't listening. However the fitter recently went on one of
their courses and knew who to speak to.

I take your point about the flow rate. I work in an industry that uses
compressed air and understand something of the relationship between mass
flow and pressure. (Which is why we have a 17inch air pipe!)

No.

The working pressure will not give an indication of pipe size.
(It should not have been necessary to phone manufactures to
confirm wp accceptable as even an appentice would know this in
first couple of weeks)
WP simply indicates that the pipe size may be suitable for your
boiler now.

15mm pipe could quite well give the correct gas flow rate for
your boiler depending on length of pipe plus fittings from the
tee for cooker and diamiter of pipe and length from meter.

Best to wait untill you can determine existing pipe size.
Then calculate if pipework correctly sized or not.

Depending on length of pipe run fittings etc even 22mm all the
way back to the meter could be undersized for your new boiler.

Is the cooker on its won pipe back to the meter? His test is not valid.
In one situation like this, I turned on the cooker and took a reading at the
meter dial of what the consumption is in m/h or cu ft/hr. I then from the
boiler gas supply fitted a flexible hose and flame trap at the end. This
went into the garden. Then turned on the cooker and opened the boiler tap
gradually until the combined boiler and cooker reading is enough, and took a
reading. It worked. You have to observe the gas cooker.

In another it was obvious that the boiler pipe was just undersized. I
figured putting in a 28mm gas meter union and a few foot of 28mm pipe at the
meter using a bend (45 degree elbows would have done) would do it - a bit of
a gamble. I did not know how much 22mm or 15mm was under the floor. But by
turning off the cooker and opening up teh bopioer tap, taking a reading,
then look at the charts it is possible to assess how much 22mm is in the
run. It did it anyhow.

Each elbow "increases" the length of a run - each elbow adds "length" to the
pipe run. The 28mm pipe significantly reduced the run length being a larger
bore.

Thanks the cooker (hob only) must be tee'd off somewhere. The pipe leaving
the meter is 22mm. Cannot see any elsewhere.

Possibly not, depending whether the inlet pressure was measured at the
pipework entering the boiler or within the boiler itself (where it would
be lower due to the boiler's inlet connector and pipework). 2mbar is
twice the allowable pressure drop. For an existing installation the excess
pressure drop is allowable as long as the boiler is working OK, but an
installer is not allowed to commission a new installation with excessive
pressure drop. (I'm not saying it never happens though.)

There's also the factor of the relative gas consumptions of the old and
new appliances: if the new requires a greater gas supply then the pressure
drop will be greater.

If the existing appliance's excess pressure drop is caused by something
like a few feet of 15mm pipe at the end of an otherwise 22mm or greater
pipe run from the meter then it may be simple enough to get a correct
supply by continuing the old pipe in 22 all the way to the new appliance.
If the existing appliance has anything like the same consumption as the
replacement then this is likely to be the case. On the other hand if it's
a much lower-rated appliance then replacement of the whole run is likely
to be necessary.

As a general comment when I'm looking at replacing boilers for people then
the size of gas pipework required is one of the first things I look at
when assessing whether I can put in a combi since it can make or break the
installation.

If the existing pipework is under a solid floor the matter is different. If
it is marginal installing as much 28mm at the meter can solve matters. But
it has to be calculated.

I have seen an illegal work-around. The meter regulator turned full on with
another one at the appliance dropping it to the required setting. It
worked. Only a boiler was used.

Rail burner boilers are not susceptible to large pressure drops.

Another work-around, depending on pipe runs, etc, is to tee of the cooker
pipe and run it to the boiler and tee it into the pipe just before the
boiler. This in effect makes the pipe run to the boiler larger, hitting the
boiler from two points.

I have seen an illegal work-around. The meter regulator turned full on
with another one at the appliance dropping it to the required setting.
It worked. Only a boiler was used.

That's going to be an interesting surprise for the next bloke who adds a
cooker or gas fire to that system!

Hope you reported that to the gas company - seeing as they own the
original regulator...

Doesn't that over pressure the meter and run a risk of leaks and death?

I didn't think gold was suitable for gas pipes.

You may need some 28mm at the meter to make the run. It needs calculating.
Look at the link gave you. It helps you work it out.

Nope. It worked and saved digging a floor up. The higher pressure gave more
gas volume through the pipe. Technically there was nothing wrong with it.
Initially the regulator was taken off, but it was thought the meter reader
would report it, so it was put back and opened right up.

22mm gas governors are readily available.

********. The regulator if the gas company's property and interfering
with it is at the very least against the contract the householder would
have with them.

You said in one breath "illegal" and in another "Technically there was
nothing wrong with it."

I said "technically" there is nothing wrong with it. Pre North Sea Gas,
there were no meter regulators. Each appliance had a gas governor. Whether
the company likes it is another matter.

It is not illegal in law, just not to the company's liking.

Is it dangerous? No.
Does it work? Yes.

Well the regulator fits between the supply and the meter so it increases the
pressure in the meter.
Without knowing how high the regulator has been wound up and without knowing
the limits of the meter you can't know the correct answer.

I do know the limits of the meters (max working pressure 50 mb).

But would you let Drivel do your gas pipework? Check you insurance policy
before answering.

I would charge you £500 for a new run. You deserve to pay lots and lots.

Doctor Drivel -it is not me (OP) who is questioning your wisdom. I hope to
be able to negotiate the price down after doing some measurements - it
wasn't a very well considered estimate.

[js.b1]

House supply used to be 75mBar, regulator is mandatory. BG did
routinely tweak the regulator, however I would rather they fix the
leaks and fit appliance taps first (rather than deliberately leaving
them of).
