A) Heating pipes: The photographs show the uninsulated central heating pipes in the third bedroom of

a 3 bedroomed maisonette on the top two floors of a six storey gallery access, walk-up block. The

uninsulated pipes from the district heating system are exposed adjacent to the radiators in most of the

rooms in the flat, despite the temperature of the pipes being in excess of 80 degrees C. High

temperatures are required by the long distribution runs from the estate's boiler house and the tenants

have no control on the output of the system, other than the manual valves on each individual radiator.

In the third bedroom, the only position for the bed means that there is a gap between the foot of the

bed and the exposed pipes.

RATING

The central heating pipes are both exposed and at a readily accessible height in most of

the rooms in the maisonette and particularly in the smaller bedrooms, most likely to be

occupied by small children. This and the high temperature at which this district heating

system is run and lack of individual control, means that the risk of an accident is

substantially higher than in an average dwelling with its own water-borne central heating

system.

As a small child could easily become trapped between the pipes and the bed in the third

bedroom, the probability of severe harm is increased.
