COMBIHEAT

POWER FLUSHING HEATER

CombiHeat is an optional heating element for use with the CombiMag Power Flushing Filter.

When undertaking the chemical flushing stage of a power flush it can be beneficial for the water to be warm, ideally around 50°C. This heat input generally enhances the performance of flushing chemicals, and reduces the time taken for a power flush.

If operational, the central heating boiler is usually the source of this heat, but if a non-functional boiler is being replaced, boiler heat may not be available.

When installing a new boiler to an existing system, it is not advisable to leave the power flush until the new boiler is operational because of the very high risk of contamination of the new boiler with debris from the old system, and this would invalidate a boiler warranty.

In these cases, and in other situations when the boiler cannot be fired, the CombiHeat can be used to raise the water temperature higher than ambient.

The CombiMag screw cap with the magnetic element is removed from the cylinder and replaced with the CombiHeat power flush heater element.

By utilising a common cylinder the CombiHeat is an economical alternative heat source.

It is particularly useful when applying heat specifically to one or two problem radiators when normal power flushing has failed to remove heavy, adhesive deposits.

The corrosion resistant element enables the CombiHeat to be used with all power flushing chemicals in common use.

  • INSTRUCTIONS

Location of the CombiHeat and CombiMag filter:

Connect the CombiMag inline between the heating system and prior to the Kamco power flushing pump, as described within the COMBIMAG INSTRUCTIONS, so that the water flow enters the bottom of the cylinder and leaves at the top.

See the diagram (above right).

NOTE: The Pressure Relief Valve supplied with the CombiHeat must be fitted to the CombiMag cylinder before the heater is used.

Magnet cleaningCleaning your magnet:

Want to know how to clean your CombiMag magnet more quickly and effectively?

Next time you finish a roll of PTFE tape, keep the empty reel. Slide it up the length of your CombiMag magnet as far as it will go before you start power flushing. When you need to clean the magnet, remove it from its chamber and slide the empty PTFE reel down the magnet. It will push the black debris ahead of it and leave the magnet much cleaner than simply grasping the magnet with a disposable glove.
