Combimate -Guaranteed prevention of limescale and soft water corrosion

Combimate is a user-friendly domestic limescale prevention device that uses Combiphos. Combiphos is a polyphosphate compound is 100% food grade material approved by FAO/WHO and compliant with the European normative standard (BS) EN 1208 that prevents scale build-up and soft water corrosion in combination boilers and other domestic hot water appliances.

• Prevents limescale in hard water and soft water corrosion
• Keeps pipework clear and energy costs down
• Prevents ‘brown’ water, protects pipework and keeps maintenance costs down
• Compact, flexible and quick to install on vertical and horizontal pip-work with top or bottom entry
• For single appliances or ‘whole house’ water supply
• Safe for drinking water and all domestic appliances -
• 100% food grade material; FAO/WHO approved and compliant with EN 1208
• No maintenance. Easy annual Combiphos top-up
• WRAS approved

Installing combimate

There are two possible installations;
whole-house supply or single appliance
whole-house supply
For this installation combimate should be plumbed
in after the stop-valve on the cold water supply to
the premises. The red removable divider tray should be
removed from inside the combimate dome in a whole
house installation so that the dome can be completely
filled with Combiphos.
single appliance installations
Combimate can be used to protect a single appliance
by placing it on the cold water supply to that appliance
e.g. a boiler in which case the red removable divider tray
should be left in place, and Combiphos should only be
put in the top half of the dome and this reduces the
amount of Combiphos required.
Inlet and outlet connections use 15 mm compression
fittings. There is minimal pressure or flow rate loss
through combimate. Vertical, top and bottom entry
pipework can be used which ensures easy retrofit
installation. combimate should be installed at least
0·5m from any local sources of heat such as boilers
or hot water pipes.
The combimate can be installed in various
configurations allowing maximum flexibility
of pipework configurations.
