In this study, utilizing two types of solar collectors, including linear parabolic (LPC) and flat solar (FPC) collectors to heat a residential building was investigated from technical and economical point of views. The performance of these two systems were obtained and compared with each other in the cold months of the year in the South‐East of Iran. The building and the heating systems were simulated in the TRNSYS software. Both the heating systems were separately analyzed from the energy and economic point of views. Results showed that the FPC and LPC heating systems delivered 51.3% and 46.7% of the received solar energy to the building, respectively. The results also showed that the solar fractions of the LPC and FPC heating systems are 22% and 8.6%, respectively. It was found that the thermal storage tank in the FPC hearing system is more useful than the LPC heating system as the LPC heating system with storage tank has a lower rate of heat loss compared to the system with no thermal storage tank. The rate of return investments in the FPC and LPC heating systems were 18.1% and 22.8%, respectively. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13121, 2019
