Energy metering
Energy metering in the heat pump is an approximation
based on the sum of the nominal emitted output during
the relevant metering period. The calculation requires
for example that the heat pump is correctly installed,
and that the flow and
Δ
temperatures on the hot and
cold sides are adjusted as recommended. The value
should therefore be regarded as an estimate of the
actual emitted output. The margin of error in the
calculation is normally put at 5-10%
In addition, the energy output is affected by the outdoor
temperature, the settings for the thermostat and room
controls and heat pump usage. Ventilation, indoor
temperature and hot water demand can play a deciding
role.
