Megaflo making high pitch noices

[alusia00]

Hello

My megaflo is making weird high pitch bird like noices when we turn heating on. Any advise what that could be?

Peasant trapped in the flue?

I think one needs to be a bit more specific and do some tests as to where the sound seems to come from and adjust what you can to see if it changes. Brian

How would a chav get in there?

That depends, how is your water heated? Electric immersion heater or via a boiler?

A chavfinch might, his pheasant couldn't.
