12L Instant Gas Water Heater Affordable Instant Natural Household Low Pressure

A 12L digital water heater is generally considered more energy efficient because it heats water only as it is needed. When the tap is turned on, the heater activates and provides continuous hot water. A digital water heater often requires less space and can be wall-mounted, but may need specific installation requirements such as larger gas lines, special venting, or additional electric circuits, which can increase upfront costs. However, a digital water heater has a life expectancy of 15-20 years and may reduce water heating bills by up to 30 percent.
