Patent ID: 8157921

Claim:
A heating installation and heating installation cleaning assembly, comprising: a heating installation having heat exchanging surfaces; and an apparatus for cleaning said heat exchanging surfaces, said apparatus having: at least one supply line for a cleaning fluid, said at least one supply line to be inserted into said heating installation transversely to the direction of the force of gravity and having a substantially straight unbent profile within said heating installation, said at least one supply line having a supporting section extending for at least 1.5 m, said substantially straight profile being self-supporting at least over said supporting section, said at least one supply line having a variable shape and an end, and said at least one supply line having an extent axis, being bendable in a first direction transverse to said extent axis, and being resistant to bending in at least one second direction transverse to said extent axis, said at least one second direction corresponding substantially to the direction of the force of gravity; at least one fluid distribution device disposed at said end of said at least one supply line; a device disposed solely outside of said heating installation and not inside of said heating installation for bending said at least one supply line only once outside of said heating installation from a direction parallel to the direction of the force of gravity to a direction for insertion into said heating installation transversely to the direction of the force of gravity and for unbending said at least one supply line from a direction for withdrawal from said heating installation transversely to the direction of the force of gravity to the direction parallel to the direction of the force of gravity; and a device for determining a length of said at least one supply line relative to a predeterminable reference point.
