my glow worm fuelsaver f has been making a loud whistling sound?
The whistling sound has begun since i had a new bathroom replaced last week. we are getting hot water and heating but when the boiler fires up it makes this loud whistling sound.we have already put a new pump on.
Try sentinel X200 this is a boiler descaler, my boiler is doning the same, and this is what i've been told to do.
I'm going to give it a try!

This could be air escaping from the case when the fan is running and if so is a dangerous condition.call in an expert.

Can't answer your query, but I have a copy of the installation and servicing booklet. I would be happy to photocopy and post to you at cost. Hope this helps.
