Black water from a radiator typically indicates the presence of corrosion or rust inside the heating system. This can occur due to various factors, such as old pipes, improper water treatment, or a lack of regular maintenance. It's important to address this issue promptly, as it can affect the efficiency of the boiler and the overall heating system. We recommend consulting with a qualified technician who can assess the situation and recommend appropriate solutions.
