INSTANT WATER HEATER

1. Heating Time: Provide hot water almost immediately when turned on, as they heat water on demand.
2. Energy Efficiency: Highly efficient as they only heat water when needed, minimizing standby heat loss.
3. Installation and Space: Compact and can be installed in smaller spaces, often wall-mounted.
4. Cost: Lower initial cost and save money in the long run due to energy efficiency.
5. Maintenance: Low maintenance with fewer components that can fail.

1. Heating Time: Usually take longer to heat water as they rely on an electric heating element and must heat a stored volume of water.
2. Energy Efficiency: Less efficient due to continuous energy consumption to maintain water temperature in the tank.
3. Installation and Space: Require significant space for the storage tank and proper installation setup.
4. Cost: Generally have a high initial cost, and higher operating costs due to continuous energy use.
5. Maintenance: Require periodic maintenance to prevent issues like sediment buildup in the tank.
