The energy required to heat hot water is not included in this value. Depending on user behaviour, the average annual energy consumption for hot water per capita is 550-900 kWh. *Peak loads from users such as high hot water demand, ventilation systems, process heat, etc. are not included in the calculation. This result does not replace a heating load calculation in accordance with relevant standards and regulations.
