There is a plastic tank directly over the copper tank with imersion heater. This plastic tank feeds the copper tank which can also be heated via the back boiler. The pump is under the flr boards.
My problem is that as I'm flushing out poor/non heating radiators of sludge I want to apply a rust inhibitor to help prevent build up. It obviously cannot go into the said plastic tank.
How could it be filled if at all?
Help please, I cant afford to pay someone to visit.

I have read your question carefully, and I suspect that your back boiler DOES NOT contribute to the heating of the radiators, it might heat the water in the copper cylinder by direct action. ( In other words the water that you use may have been to the back boiler and back)
You did'nt say how the radiators were normally heated. You may have a red pressure vessel beside the boiler for instance with a gauge reading about 1 bar in which case it will involve a lot of work. If further advice needed email me.

First read book on boiler. Next check the water pressure in boiler. Should be between 1-1.5bar. If the boiler heats the hot water check that the hot water / heating switch is in the right position. If all these requirements are made then my advice is either get a heating engineer or a boiler representative to check out boiler.

There should be a small plastic or possibly metal tank (header tank) which keeps the heating circuit topped up. Normally in the loft, but certainly higher than the highest radiator. You may have a primatic cylinder which does not need a F & E tank, but is a single feed indirect cylinder.
