(I don't know which specific model it is from the range atm)
I'm just trying to work out what's making it run so noisily - the rads
are bled, but even with them off it sounds like it's pumping a huge
amount of air around the system (gurgling like a b*stard to be more
precise)
I've just tried to lower the temp at the boiler end in case it was
kettling causing it (don't normally notice if it is, as it's in a
garage)
...possibly - Ed or the other chap who repairs PCBs might have one to
hand, but I might get back to you...
Thanks for the reply :-)
OK thanks for that - for some reason I thought they'd gone out of
business !
Just a small update, it's the Spacesaver Mk2 50BR model

The bloke who repairs PCBS ?
You mean the one who pays other people to repair them for him ...

I prolly have one, but I doubt it will be of much use for what you're
describing
If you have a leak somewhere that's letting air in, it could be anywhere
in the system not necessarily in the boiler
You might find that your auto bleed valve isn't working properly, it
will be somewhere at the top of the boiler and is usually gold in colour
and circular with a screw top an inch and a half in diameter and two
inches tall
Check out the joints in the boiler to see if there is evidence of water
leaks especially around the heat exchanger
The only other (continually) moving parts in the boiler are the fan,
and the pump if its part of the boiler

He's got enough positive feedback for me to consider him a worthwhile
bet !
They don't list that model anymore :o(
It's not a pressurised system either, so could be anywhere :-}

I'll check it out over the next few days...

No sign of leakage internally, and the pump is seperate :-}
I still don't repair them myself much any more

If your system is open vented then check the feed & expansion tank (probably
in the loft). The float valve may have stuck causing the tank to run dry, a
few yanks up and down usually frees it and gets the water running again.
Alternatively if the tank is full then check that the cold feed is not
blocked where it tees into the system.
Thanks for that - we've already drained and refilled it a few times
recently while decorating, and everything seems to work as normal
though :-}
It certainly seems like an air problem then if it has been drained &
refilled several times.
You should be able to vent most of the air through the pump vent screw.
Loosen the screw and run the boiler. Put a container or piece of rag under
the pump to catch the drips.
Ahh, I didn't know they had one, i'll have a look tomorrow :-)
(only ever had a combi before this)
