Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.
A single-family storage water heater offers a ready reservoir -- from 20 to 80 gallons -- of hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank through the dip tube where it is heated, ensuring that the tank is always full.
The main benefits of modern storage heaters are: They''re cheaper to run than other forms of peak-hour electrical heating systems. Modern storage heaters have some clever built-in features such as programmable timers, fans, and built-in thermostats. They''re exceptionally quiet, even the ones with a fan.
