5.4.2 Electricity meters and rates
For connecting a heat pump to the power grid, consent should be obtained from the competent
electric utility company and connection conditions should be requested. In this context, it is also
necessary to provide data regarding the building and about the heat pump and its operating mode.
If it is possible to utilise special electricity tari󰀨s for heat pumps, possible electricity shutdown times
and their duration are to be requested and taken into account for design.
The power consumption of the heat pump is measured by a dedicated electricity meter, to which all
power connections of the heat pump are connected, and used to determine the seasonal coe󰀩cient
of performance and to calculate a deviating special heat pump tari󰀨.
ATTENTION
Danger of water pipes freezing up during electricity shutdown times by the utility company
If electricity shutdown times imposed by the electric utility company coincide with frost periods,
there can be frost damage, if the device ensuring frost-free operation of the heat pump is also
a󰀨ected by the electricity shutdown times.
► Wen connecting the base pan heater or other devices ensuring frost-free operation to the
power grid, make sure that it cannot be a󰀨ected by the electricity shutdown times.
