The capacity of water heater

When buying a water heater or geyser, it’s imperative to consider family size and purpose. If you have 2 to 3 family members, an instant water heater will do the job if you don’t use the shower. If you have 4 to 8 family members, you will need more than 25 liters of water; this is when the storage water heater comes into action.
