Further Quality Procedures (Structure) ~
- Provision of insulation to be continuous. Gaps are
unacceptable and if allowed to occur will invalidate the
insulation value by thermal bridging. - Junctions at elements of construction (wall/floor, wall/roof)
to receive particular attention with regard to continuity of
insulation. - Openings in walls for windows and doors to be adequately
treated with insulating cavity closers.
Further Quality Procedures (Energy Consumption) ~
- Hot water and heating systems to be fully commissioned on
completion and controls set with regard for comfort, health
and economic use. - As part of the commissioning process, the sealed heating
system should be flushed out and filled with a proprietary
additive diluted in accordance with the manufacturer's
guidance.
This is necessary to enhance system performance by resisting
corrosion, scaling and freezing.
- A certificate confirming system commissioning and water
treatment should be available for the dwelling occupant. This
document should be accompanied with component
manufacturer's operating and maintenance instructions.
Note: Commissioning of heating installations and the issue of
certificates is by a qualified `competent person'' as recognised by the appropriate body, i.e. CAPITA GROUP, OFTEC or HETAS. CAPITA GROUP ~Gas Safe Register' of Installers (formerly CORGI).
OFTEC ~ Oil Firing Technical Association for the Petroleum
Industry.
HETAS ~ Solid Fuel. Heating Equipment Testing and Approval Scheme.
