Answers: Water carries nouns bubbles which get filter into the boiler/radiator system...The air from the hose builds up in the top of your radiators, whic is why you hold to bleed them every few weeks. It could be the froth is caused by an anti rusting agent placed within the boiler system. Its not harmful.
It sounds as The pump may own been sucking nouns in for the concluding year, especially if the system pressure has be allowed to drop. This may have done rather a lot of sabotage, causing corrosion. The corrosion products may be depositing surrounded by the boiler too. You need a competent heat engineer to embezzle a look at it and sort it out.
