Heating systems can over time develop a build up of sludge, scale and corrosion debris. This can cause pipe work and radiators to clog up, cold spots on the radiators and the system to be less efficient. A sentinel Jet Flush 4 power flushing machine is used to clean the system using water at low pressure and high velocity. The direction of flow can be changed to help loosen and remove sludge from the system. On completion, chemicals are added to help maintain the life and efficiency of the heating system.
