Total Energy used

32.4kwh/m2y x 163.7m2=5303 KWh/y - 5303KWh/y x 1.50kr=79545kr/y English sterling at 10.7 to the £1.00

Total Energy consumption for electric, heating and hot water one year = £743.41*
Total Energy consumption:
 is 32.4kwh/sq/year

*Based on the climate in Northern England with an Air source heat pump.
The total energy consumption will decrease slightly when you come further to the South of England due to the climate and temperature.
