..., the surrounding thermal losses decrease from 2505 W h to 2286 W h as the emissivity decreases from 0.74 to 0.14. This drop in energy losses (−219 W h) is recovered by the water of the tank (1207–1426 W h) and serves to rise its temperature (41–46 °C) and the thermal efficiency (23–28%). We can deduce...
