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
∆
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
decisive role.
