Electric storage water heaters have an internal tank and a heater (heating element). Water in the tank is heated by means of PETN - all simply and reliably. The heating time depends on the capacity of the heater, tank volume and temperature of incoming water into it.
Gas instantaneous water heaters or gas water heaters, used for heating water passing gas burner. For ignition of gas in the columns used pezorozzhig (click) or electronic ignition (Auto Wake-up when you open the tap). These water heaters come in low, medium and high power.
