Answer:
the main advantage of a 240 volt heating unit over a 120 volt heating unit is that at 240V, you can get the same amount of power with less current than you'd need at 120V. This means that 240V requires less wiring , and you can fit more heaters on a 240V circuit than on a 120V circuit . Additionally, 240V power is more energy efficient and cost-effective in certain situations. However, it's important to note that the size and capacity of the heating unit can be a factor as well, and that both 120V and 240V heating units have their advantages depending on the specific needs and circumstances.
