Presented in the paper is a brief description of the solar thermal water pump and its operation. The performance of such a solar water pump working on a flat‐plate collector of exposed area of 1 m 2 is studied for three different discharge heads, namely 6, 8 and 10 metres. The thermodynamic analysis reveals that, while the number of cycles and the quantity of water pumped per day decrease with an increase in the discharge head the overall efficiency increases.
