Installing the G-Power Easy district heating substation
The district heating substation is to be installed in a single-family house technical room that has a floor
drain.
The minimum space requirements of the equipment and heat energy meter must be checked from the
heating company.
Leave 800 mm of free space in front of the heat energy meter and the main distribution board. Do not place
any pipes above the main distribution board.
Things to note before any installation work is performed
Only a contractor who is approved by the energy company can carry out district heating connections. The
heating piping of the substation can be connected from above, below, apart from the cold-water pipe.
The connectors may become loose during transport. The connectors should be checked and, if necessary,
tightened during installation.
NOTE! The circulation pumps on the G-Power 3/100 substation are turned to the side on delivery. Turn the
circulation pumps on installation so, that the control panel faces forward.
Installing the G-Power substation on the wall
Attach the wall mounting rail carefully on to the wall.
Lift the district heating substation to hang from the ail
and attach the heating substation on to the wall through
the mounting holes on the bottom of the retaining
frame.
District heating substation is ready to be connected to
networks.
Connection of DHW circulation
According to Finnish Energy recommendation K1 / 2013, the standard connection of the detached house
includes a domestic hot water circulation pump as standard. Hot water circulation shortens hot water
waiting time and improves control performance
If a hot water circulation pipe is or will be built on the property, the hot water circuit of the G-Power
district heating substation is connected to the marked piping.
If the property does not have a hot water circulation pipe and cannot be reasonably constructed, connect the
circulation pipe as far away from the G-Power substation as possible, e.g. to the domestic hot water
manifold.
NOTE! The length of the circulating pipe must be at least 3m and the recommended pipe size is at least
DN15.
