Not often or even regularly but sometimes.
NO smoke or fire or anything! Seems to be working as it should otherwise.
But when we use the hot water a lot or like today it's a bit nippy where we are and so we've put the heating on for couple hours just.
I really don't want to have to call anyone out especially over a weekend if I can avoid it but it IS annoying when it happens.
We have the world's smallest kitchen and we're having to keep kitchen door shut on days when we're using the hot water a lot or having heating on.
Can anyone help?
It's fine for now but as I say annoying when it does happen.
