Works fine and all radiators warm up correctly. Boiler is ancient but serviced each year and can still get parts. Radiators bled fine.

Problem is noise on start up upstairs. Really noisy and sound of rushing water. Sometimes banging noise and loud hum. After a while this quietens.

Problem is it wakes children up at 4.30am when heating comes on. The noise is loudest in room next to the H/w cylinder and below the expansion tank. The pump is in there too.

Advice appreciated.

HAPPY NEW YEAR

Hi,

Thats good going for a boiler - which one is it?

Still air in it / sticky pump, bleed air out of centre screw in pump and check for movement etc on start up.

Also, it won't wake the kids if you programme it to come on a lot later!!

Boiler is Concord WRS, think it's made by ideal.

Bled some air from top of radiator in bathroom - towel radiator. Others okay

Pump is Euramo Gold star - looks ancient too, telephone number on it looks old school - not enough digits, presume it's the big screw in the middle to bleed this.

Everything is okay when running, just noisy on start up.

Yes big screw in middle- remove it = water > rags - see what the results are.
