2.5.3 Regulations for the prevention of accidents
When carrying out works such as solar installation work
it is necessary to do so in a safe and workman like man-
ner, taking due care of any aspects of the works that
could result in injuries to person in or about the building
as well as workers, passers by and the general public at
large. To that end these works must conform, but not be
limited to, the current regulations in force such as the
following
Health and Safety at Work act 1974
Work at Height Regulations 2005.
Electricity at Work Regulations 1989
All necessary Building Regulations.
Work should be preceded by a risk assessment covering
all aspects of health and safety risks, or training require-
ments that can reasonably be foreseen to be
associated with the work. All scaffolding in the UK, other
than prefabricated (zip-up) scaffold towers, must be
designed and constructed by a vetted contractor, and
have suitable kick boards, hand rails and where appro-
priate netting. Areas around the scaffolding should be
zoned off and marked with suitable warning signs to a
suitable distance to protect persons from falling objects.
Workers should have available and use personal protec-
tive equipment as necessary. This would include equip-
ment such as fall protection systems, safety gloves,
goggles, dust masks as well as any specialised equip-
ment that may be in use such as lifting and handling
equipment.
The completed works shall comply with all necessary
BS EN Standards and Codes of practice as well as Build-
ing control or planning requirements and be confirmed
where necessary by notification to building control or
the appropriate competence based notification body.

Design and function of solar heating system
The solar heating system consists of four main compo-
nents:
– The collectors, which absorb the solar radiation and
make it useful
– The solar controller, which monitors, displays, and cont-
rols all system functions
– The solar pump unit, which is responsible for trans-
porting the solar heat
– The solar cylinder
The Vaillant solar heating system is a closed hydraulic
system in which heat is transferred to the cylinder via
the heat exchanger with the help of the system's special
heat transfer fluid.
On days when the solar radiation is not sufficient to heat
the hot water in the cylinder, the cylinder water must be
reheated using a heating system. This can take place
using a gas-fired wall-hung boiler or an electric immer-
sion heater.
