As global energy demand continues to rise and traditional sources increasingly fail meet sustainability targets, conventional domestic hot water systems that rely exclusively on either geothermal or solar face inefficiencies seasonal limitations. To tackle these issues, this study introduces an innovative supply system combining MDBHE with a PV/T heat pump investigates its thermal performance. This utilizes elevate the temperature of extracted from MDBHE, while supplying power through photovoltaic electricity. The results indicate increasing circulating flow rate improves extraction capacity MDBHE. However, also leads higher resistance increased requirement for pump. Additionally, at 32 m3/h, fails extract when inlet exceeds 34.5°C. Furthermore, module area 2000 m2, radiation intensity 600 W/m2, depth m, can attain maximum 50.9°C, contributing 63%. Moreover, coefficient performance (COP) reach 5.8, outperforming systems.
