Appendix
8.1 Regulations and Directives
When designing, installing and operating the system, observe the following standards and directives in particular:
General regulations and directives
BImSchG
Legislation on the restriction of
sound emissions (Germany: TA

DIN 4108
DIN 4109

(cont.)
Federal Immission Act [Germany] heat pumps are "Systems" according to the Federal Immission Act.
The BImSchG [Germany] draws a distinction between systems that require approval and those that do not
(paras. 44, 22). The systems that are subject to approval are listed in the 4th Federal Immission Protection
Order (Bundesimmissionsschutzverordnung, 4. BImSchV).
Heat pumps of any kind are not subject to this order. This means that heat pumps are subject to
paras. 22 to 25 BImSchG [in Germany], i.e. they must be set up and operated in a way that ensures that
avoidable disturbances are restricted to a minimum.
For noise emissions emanating from heat pump systems, observe all applicable noise protection require-
ments.
