Summary

Thermal energy storage (TES) has been considered for integration into residential heating systems with air source heat pumps (ASHP-TES) as it can bring benefits to users and the grid. There are several simulation tools that can be used to determine whether the introduction of TES is economically attractive. However, these tools are not accessible to all
stakeholders in the energy market, which can hinder the deployment of such systems. In this paper. a new analytical method for estimating the economic performance of ASHP-TES systems for homes is proposed. The method uses known parameters of the heat pump, dwelling, and storage, and applies a simplified calculation procedure that can
be easily implemented in spreadsheets to estimate the levelized cost of electricity and storage for specific ASHPTES projects. The method was tested in five distinct locations in the United States. Compared to the simulation results for the levelized cost of energy (LCOE), the relative deviations ranged from 0.5% to 3%. Additionally, the error of the levelized cosst of storage (LCOS) calculation method was ten times smaller than the ASHP-TES system viability criterion. This indicates that the method can be used to generate initial estimates of system performance and viability. As the method eliminates the need for sophisticated tools, it could help more engineers, architects, contractors, and clients to quickly decide whether an ASHP-TES project is worth exploring further. Although the results are encouraging, the impact of the simplifications made in the method need to be further investigated.
