Economic evaluation of the energy efficiency of the cottage electric heating system

Abstract

The 2020 global crisis caused by the coronavirus pandemic has increased the demand for individual suburban housing. The need to create an efficiently managed infrastructure of life support and energy consumption systems requires the development of control technologies on each stage of the life cycle. An urgent problem is to ensure reliable and efficient heat supply for low-rise residential buildings. One needs a reliable tool for the feasibility study of the decision-making process during an object life cycle. The paper considers a comparative assessment of the total cost of ownership of heating systems for cottages with the same operational and technical parameters. Environmentally friendly options were preferred. The total costs of heating systems for cottages are estimated using the developed software product, considering creation and operation costs. Calculations of electricity consumption for heating are most profitable using modern materials with high thermal insulation characteristics. A cable floor heating system and room temperature automatic regulation significantly reduces financial costs since the preferential tariff for electricity at night is lower than during the day. The use of electricity for heating cottage settlements allows to implement controlled energy consumption for a more even use of the power plant capacities.
