Most central heating systems develop sludge over time which is caused by a series of different chemical reactions. It starts with a small build up of this deposit in the bottom of radiators, as the water flows around these deposits they gradually build causing cold spots on radiators and blocking pipe work. This restricts the flow of circulating water, causing strain on crucial parts of your heating system such as your boiler and pump. The cause of this is a reduction of its effectiveness, efficiency and lifespan.
Our power flushing machine employs a high velocity pump and is a specialist device. This, combined with cleaning chemicals, removes the built up sludge. When clean this is then flushed out and replaced with clean water.
