Boiler Question - Pump
Discussion
Fired up the CH yesterday and it was banging and popping like a goodun!
Turns out it's the water boiling in the pipes as it's not getting pumped around the system.
Am I right in that if I wire up the pump directly to the mains that it should work? Well it doesn't.
It's a Wilo Gold pump but I'm not sure what I need to replace it, I live in a Victorian 2up2down and was thinking is a Wilo Gold 50 ok to do the job?

Great!
Just had a "plumber" round just to double check, didn't tell him what I knew, this is what he said; "Pumps gone, pump overrun stats gone, Thermo couplings gone, may as well get a new boiler as this one is about 25 years old. £90 for pump, £50 for stat, thermo coupling £25 plus labour £350 or new boiler £860"
WTF!
I didn't say a word just stood by the open front door and shut it behind him.
Yes boiler is very old but it's been in storage from new and was only fitted about three years ago. Pump is £40 from Screwfix, overrun stat, well how can he tell if that's gone if the pump is faulty and thermo coupling £5 from Homebase Prick!
I am not tarnishing all plumbers with same brush here just this guy is a piss taking w
ker.

A)Your boiler stat is fubared
B)There isn't enough water in your central heating system, ussually caused by a blocked feed pipe from your F+E cistern.
If you can hear it making a noise like a kettle boiling, I'd say B.
Heat will still circulate naturally without the use of a pump. If your boiler is 25 years old, I'd doubt it has a pump overrun facility.

I will check the cistern and water is flowing in the pipes later in week, however this doesn't explain the fact that the pump is not pumping when directly connected to power- unless it has a no water cut off thing within the pump? Doubt it.A)Your boiler stat is fubared

It's not quite 25 years old, more like 10! It does have a pump overun cut off as I have all the paperwork and schematics.
Cheers for your help.
If it isn't working wired directly to the mains, I'd say its fubared!
Tip, if you have screwdriver slot type pump valves, do not touch them, they will leak if you turn the slots, drain the entire system down!
It could just be the pump thats causing it, I know older boilers would circulate without a pump, but I think newer one actually require the water to be pulled away from the boiler.
