CalFlush is a powerful cleaning system designed to remove deposits in central heating systems. Effective flushing can be achieved with minimal disruption.

Central heating systems can gradually build up a combination of scale, sludge and corrosion by products within the boiler, pipework and radiators.  This manifests itself as cold spots on raditors, failure to pump to the furthest radiators, and noise in the boiler.

Central heating systems also need to be flushed prior to filling with preservative in order to remove flux and other deposits before commissioning for the first time (BS7593:1992).

It can often be time consuming or impractical to remove radiators for cleaning out severe blockages.  Even when they are removed, the only flushing capability usually available is with cold water from a hose at mains pressures and flows.  This will not loosen or remove sludge which has bonded to the inside of radiators or the remainder of the heating system.

The Calmag CalFlush Flushing System is the culmination of many years experience of the use of Calmag Heating System treatment chemicals with high flow, low pressure cleaning sets.

The opening at the top of the tank allows for chemical cleaners, such as the CalFlush Powerflush Pack, to be added easily. Furthermore, flushing quality can be visually monitored by checking the water returning to the tank or drain. When the system is in operation, dirty water can be sent to the drain while continually refilling with fresh water.

The unit is compact in design for ease of movement. It has also been ergonomically designed with a large diameter handle so that it can be picked up easily when empty.
