As stated before, power flushing radiators must be done at least once every five to six years. Power flushing is one such service that is not needed to perform annually. A single power flushing is enough to keep the system going for at least five to six years. When a technician arrives to perform a power flushing service, the time taken to flush the radiators depends on the number. Such as, at home, the maximum number of radiators can be up to 6. However, in offices or other commercial properties, there are around 12 radiators. These technicians charge a fee for flushing every extra radiator; hence, the more the number of radiators, the more the charges are. A power flushing service is much more affordable for homes than commercial properties.
