Regenerative electric heating projects are major livelihood projects that promote clean heating. However

current economic evaluation methods of thermal storage electric heating systems aren’t considering factors such as differences in the life of different equipment and related“coaltoelectricity”subsidy policies

which may lead to unreasonable investment and excessive heating costs for residents. An economic evaluation method of thermal storage electric heating schemes based on equivalent annual cost in life cycle is proposed. Firstly

the main equipment in the thermal storage electric heating system is modeled. Then

the economic evaluation model of the thermal storage electric heating based on equivalent annual cost in life cycle is proposed. Finally

the effectiveness of the proposed method is validated by an typical example.
