No. Hot water radiators operate within a “closed” system where there's little or no corrosion taking place. Flushing these radiators will only cause you to add more water to the system, which will create more corrosion, and so on, and on.
Can I flush my central heating system myself?
There are a couple of ways that you can clean the sludge out of your heating system. The first is called a powerflush, which is both the name of the method and also a physical device that your heating engineer will use.

How to flush a radiator with tap water?
Pour tap water in the radiator to flush it. Continue pouring in one gallon of tap water, run your vehicle with the heat on and drain it once it has cooled. Once you notice that the water is running clear, then flush the radiator one final time using distilled water. Do not use tap water for this purpose, as tap water contains minerals that could lead to premature rusting of your cooling system.
How to clean a radiator?
Put radiator cleaner and distilled water in your radiator. Pour these fluids into the radiator reservoir, which is where you took off the pressure cap. We recommend using a funnel to ensure that all the water and cleaner goes inside. Pour the entire bottle of cleaner in first, then add one gallon of the distilled water. Once the radiator is filled, put the cap back on. You can easily get radiator cleaner at an automotive store near you — check the owner’s manual for your vehicle to see if they suggest a specific radiator cleaner or amount.
