Hi, please help,
My ageing Myson Marathon boiler in my open vent system seems to be generating plenty of heat. The boiler inlet and outlets are very hot as is the pump. The two way honeywell valve activates. I have tried a mains flush and a bucket flush at all the rads and all seems fine. I attached a flexi pipe and bucket to an upstairs radiator and after drawing off a couple of gallons I get good heat to the downstairs radiators. Pump is fine.
Last week I tried Sentinal x800 but still have poor circulation. Advice would be very welcome.
