with the relevant requirements of the Local Authority
and the Building Regulations relevant to the location of
installation.
BS 8558:2015 Services supplying water for domestic
use within buildings and their cartilages.
Water Supply (Water Fitting) Regulations 1999 or The
Water Bylaws 2000 (Scotland).
Heating System
The installation of the heat pump should follow best
practice as covered in the following:
BS 5449 Forced circulation hot water central heating
systems for domestic premises.
BS 15450 Heating systems in buildings – Design of heat
pump heating systems.
Ventilation System
Any ventilation system should be designed and installed
in accordance with Building Regulations, England &
Wales Approved Document F1 and Scotland Technical
Standard Section 3.14 Ventilation. Only this will ensure
hygienic room air and prevent any dampness to the
building structure.
To be able to ensure a high degree of efficiency and an
extremely comfortable living environment, we recom-
mend that the installation of any ventilation system
should be planned and this plan be strictly followed by
the ventilation engineer.
The discharge air duct work to outside must be insulated
to ensure condensation does not form in the duct work.
