Thanks for the replies, I managed to download an old manual for my rayburn which dates back to the 60s, the system works with a direct hot water cylinder and it states not to fit a radiator although it does recomend a heated towel rail run of the flow and return pipes, at present I have the rayburn turned off (it was converted to oil some years ago fom M/F) I have concluded with your help and others that there is some type of restriction in the back boiler system which requires flushing out, I am unsure if I can do this, any hints? also the drain cock on the pipe next to the back boiler looks as if it has not been used for decades, I have asked a couple of local plumbers for a price to flush the back boiler and I am waiting for a response although one suggested £350 which I thought criminal as a new boiler only costs £100 and the replacing is a simple slide out/slide in which the manufacturers state is a 15 minute job, anyhow if you can steer me in the right direction to flush the system (would I use a chemical?) I would be very gratefull,....
