PRT Installed Installed PRT The Ecoplus PRT can be installed anywhere in the house provided that it allows easy access to the required pipes.

In most cases, it is installed in the boiler-house or the airing cupboard. As the unit may become hot, the best position for the PRT is on the floor or resting on a flat surface. The exact location of the unit will vary depending on the configuration of the central heating system in which it is being installed.

The diagrams in the following pages show some of the possible central heating system configurations and are designed to help you during installation.

Scenario 3 - Flow and return at high levels for the radiators through the attic.

This is a typical installation in cases where the heating system was installed after the house was built.

Scenario 3

Scenario 4 - Flow and return at high levels to feed the copper cylinder.

Scenario 4

Note

The Auto vent is placed on the pipe connected above the PRT (port 1) to exhaust the gases. If the Auto Vent was not put there, the gases could not vent out the expansion pipe.

To prevent gravity flow from cylinder when the system shuts down, place a non-return valve on the primary line.
