In addition to the full hose and adapter set supplied with every Kamco Clearflow power flushing, a summer promotional offer sees an infrared thermometer worth £40 added to the kit.
Experienced heating engineers will switch on the boiler and carefully check the condition of a heating system before recommending a power flush. Checking that all radiators are equally and evenly hot is part of the assessment. An infrared thermometer with laser dot guidance is a quick and easy way to check how even a radiator’s temperature is across the surface and is effectively the engineer’s eye into what is happening inside the system.
Cold areas in a radiator indicate that a build-up of sludge and corrosion debris is preventing hot water from reaching the area – and the answer is invariably ‘power flush the heating system’.
Summer is a great time for engineers to promote a power flush of older systems, to restore efficiency at a time when heating is not so critical and inconvenient to a householder, and the thermometer is a handy tool to demonstrate where a heating system is lacking. The thermometer is accurate to within a 1/0th of a degree and gives a professional image to a heating engineer.
Clearflow pumps generate a high velocity flow of water that impacts on and dislodges sludge and corrosion deposits. Heating the system to 50o once flushing chemical has been added improves the speed and efficiency of a flush. The cleaning process is improved by rapidly reversing the flow of water to create turbulence in radiators. Fresh water is then driven through the system to purge the debris to waste.
During the power flush engineers should continually check radiator temperatures, and once they are consistent all over, and the system water is clear, then the power flush has been successful.
The promotional offer of a free infrared thermometer runs until the end of August whilst stocks of the thermometer last.
