Abstract :The economic analyses of air source heat pump usage in İzmir was conducted. Effect of heating water temperatures and electricity tariffs on the energy economy were investigated by using hourly outdoor temperature data of İzmir. Single- and multi-rate electricity tariffs for a residence in İzmir province were compared. Preferring the multi-rate electricity tariffs in air source heat pump results in decrease of heating costs. If the energy consumption is priced using a multi-rate tariff, the energy cost will be reduced by 20%. There is a lower temperature requirement for underfloor heating compared to conventional heating. Energy costs in underfloor heating can be lowered compared to natural gas. The hybrid system (Heat pump + natural gas), which allows to use the most economical energy source on an hourly basis, can save 24% compared to the use of only natural gas.Keywords : Air source heat pump, İzmir, Multi-rate electricity, Natural gas, Energy economy
