Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed without storing it in a tank. When you turn on a hot water faucet, cold water flows through the unit where a powerful heat exchanger instantly heats it up. The heat exchanger uses either a natural gas burner or electric element to heat water immediately. These efficient units heat water instantly as it passes through the heater, ensuring an endless supply of hot water while reducing energy consumption. Tankless water heaters are compact, space-saving, and more energy-efficient than traditional tank-based systems. They are ideal for homes looking to save space and reduce heating costs. With proper installation and maintenance, they can offer long-lasting performance and comfort. 

Installing a tankless water heater can significantly improve energy efficiency and ensure hot water on demand. This simple, step-by-step guide will help you understand the installation process, from choosing the right model to connecting it safely. By the end, you will enjoy reliable, instant hot water with improved space efficiency.

Tankless water heaters come with a range of benefits.

• Energy efficiency: Tankless 25 litre water geysers only heat water when it is needed, reducing energy waste compared to traditional models that continuously heat a storage tank.
• Space-saving design: Without the need for a bulky storage tank, these units take up much less space, making them ideal for smaller homes or apartments.
• Endless hot water supply: Tankless models provide hot water on demand, ensuring you never run out, no matter how much you use.
• Lower utility bills: With improved energy efficiency and reduced standby heat loss, you can see significant savings on your energy bills over time.
• Long lifespan: Tankless water heaters typically last longer than traditional Bajaj 3 litre instant geysers, providing long-term value and reducing the need for frequent replacements.

Following is a list of tools that are required for installation of a tankless water heater:

• Wrench and pliers: Used for tightening plumbing connections and adjusting fittings.
• Drill and drill bits: Required for making holes in walls to mount the tankless water heater.
• Screwdrivers: Essential for securing screws on the unit and for assembling parts.
• Tape measure: To ensure proper positioning of the water heater, especially for ventilation and clearance.
• Pipe cutter: For cutting water supply lines to, the appropriate length.
• Level: Ensures that the water heater is installed straight and correctly aligned.
• Teflon tape or pipe joint compound: To seal threaded plumbing connections and prevent leaks.
• Wire cutters and strippers: For handling electrical connections and ensuring proper wiring.

Follow the below steps to install a tankless water heater easily:

• Turn off the power and water supply: Begin by shutting off the electricity or gas supply and the water inlet.
• Mount the water heater: Choose a suitable location, typically on the wall, and secure the unit using screws and a level to ensure it is aligned.
• Connect the water lines: Use pipe cutters to adjust the plumbing and connect the water supply to the inlet and outlet of the tankless heater.
• Install the venting system: For gas-powered models, ensure that you install the proper venting pipes for safe exhaust. Bajaj 5-litre water geyser models will require wiring, so proceed with caution.
• Wire the heater: If it is an electric tankless water heater, connect the unit to the power source using the appropriate wire gauge, ensuring all connections are tight and secure.
• Test the system: Turn on the water and electricity to test the heater’s functionality. Ensure that water flows correctly and that the unit heats up efficiently.
