Did someone leave a dead body in that tank?:tongue3: Seriouosly though my red stuff was packed hard, rusty-red not blood-red.

Good photos Bunker.

Many consumers believe that cleaning the F + E tank tank and removing the blockage is the answer to their problems, it is on a temporary basis.

They are but symptoms of what is happening in the heating system, symptoms that if addressed properly can mean the difference between a short time to a replacement heating system and getting another ten years without major expenditure.

:iagree: It's fixing the symptoms but not the cause :iagree:

Thanks for all the input. Problem now resolved. The oftec registered heating engineer who installed the recent boiler (about 3 years) never took out the hot water cylinder thermostat from the old gravity feed system. Quite alarmed really. Installing a pumped system with a blockage in the pipework leaves me feeling let down by one of your peers.:disappointed:

I doubt it was a problem at the time, the blockage would have prevented him filling it so he would have had problems then and there.
As Peteheat says and echoed above, once the blockage is removed, make sure you treat the water again (flush,clean, flush and inhibit)

Do wholeheartedly agree with your comments and have flushed, cleaned, flushed and inhibit. Am still puzzled why a thermostat on the exit of the hot water coil would be left in a pumped system. Even though it wasn't causing a blockage initially, the potential to do so remained, especially since those old gravity thermostats have a history of malfunctioning. Anyhow, the main thing is,no longer rusting out my radiators or heat exchanger. :angry_smile:
