Fernox F1 Central Heating Inhibitor 500ml – Radiator Rust & Scale Protector

Is your heating system making strange noises or failing to warm up your home evenly? Over time, sludge, rust, and scale build up inside your pipes and boiler, forcing your system to work harder and driving up your energy bills. It is a frustrating cycle that often leads to costly repairs or premature boiler failure.
