It is now a requirement to measure the electricity being used by the heat pump so the end user can see what the unit costs to run, 
although the unit can now estimate the  energy used we always recommend 2 smart electric meters are used. Ideally it should measure 
the total draw for the heat pump (outdoor and indoor unit combined). The outdoor unit takes most of the current so in many installations 
it will only be used to measure the outdoor unit.
