I have a conventional open vented heating system with a Potterton CF boiler feeding both central heating and domestic hot water.
My problem is that the Myson air separator clogs up with brown paste every two years approximately. The symptoms are extended running of the pump and increased heating times.
This problem has been around for the last 15 years since I bought the house but is something I have come to live with.
To improve hot water recovery times (four ladies in the house!) I changed the two port electric valves for a Grundfoss Plumplan unit which has two pump heads in one body and electric valves become redundant. An excellent piece of kit when working well.
Back to the problem – the brown paste builds up in the air separator and flow pipe work restricting the bore of the pipe and will eventually totally obstruct the pipe if not cleared away.
To enable a quick clean out, the pipe work has been changed with compression joints allowing easy disassembly of the air separator for cleaning.
Cleaning is achieved with a tooth brush and cold running water.
Once cleaned out and reassembled all is well for at least 18 months.
I know how to deal with this problem but what I would like to find out is why does it occur?
Do I still need the air separator?
Help please.
Many thanks
