The Daily HWS demand for the Energy Calculation is based on litres/per person/per day.
The Daily HWS demand has units of l/per/day in Hevacomp v25, which should be read as litres/person/day. In Hevacomp v26 this has been changed to l/person/day to avoid confusion.
Taking this into account, the limit of 500 l/person/day will provide a more than adequate HWS demand for the calculation.
The total HWS demand will be calculated from the figure entered and the occupancy of each individual room.
