How did you get the sand out?

Generally, these device are connected to the main COLD water for maximum efficiency. So, when you take a shower, they warm a little the cold of the shower and improve the temperature of the cold water entering the tank.
For max efficiency, you want a maximum of cold water entering the heat exchanger.
