Everything to Know About Cylinder Geyser


If you are looking for an efficient and reliable way to heat water, a cylinder geyser (gas geyser) might be the perfect solution. A typical cylinder geyser can heat ~90 gallons of water in less than an hour which is why they are perfect for factories or in big Indian households, where rapid heating is required for multiple taps. These appliances have become increasingly popular in recent years due to their energy efficiency, cost-effectiveness, and convenience. Here, we will explore everything there is to know about cylinder geysers, from how they work, to the best options available in India.

Now, let’s see what is Cylinder Geyser?

A cylinder geyser, commonly known as a gas geyser, is a water heating system that uses liquefied petroleum gas (LPG) or natural gas as its primary fuel source for the heating process of water using a burner. It delivers hot water instantly using power that you can operate manually. It is an ideal investment since it does not require a tank or electricity and provides a steady flow of water and can thus help save a lot of time, especially during winters. Unlike traditional storage water heaters, energy-efficient gas geysers heat water on demand, eliminating the need for a large storage tank. They take just a few minutes to heat up and provide hot water and have no limited heating power, which is why the heating output is instant. This not only saves space but also reduces standby heat losses, making them more energy efficient.

How do Cylinder Geysers Work?

The working principle of cylinder geysers or gas geyser is simple. When you turn on a hot water tap, a sensor detects the water flow and activates the geyser's burner. The burner then ignites, heating up a copper container or heat exchanger through which the water flows. As the water passes through the heated coil, it absorbs the heat and emerges as hot water from the outlet.

Pros of Cylinder Geyser

Benefits of Cylinder/Gas geyser

Cylinder geysers offer several benefits over traditional water heating systems. Below are some benefits of gas geysers:

  • Energy Efficiency: Since gas hot water systems heat water on demand, they consume less energy compared to storage water heaters.
  • Space-Saving Design: With no need for a large storage tank, cylinder geysers have a compact and sleek design, making them suitable for homes or apartments with limited space.
  • Continuous Hot Water Supply: As long as there is a steady supply of gas and water, cylinder geysers can provide an endless stream of hot water, making them ideal for households with high demand. Even in occasion of having no power supply, gas geysers would not be affected.
  • Low Maintenance: Cylinder geysers require less maintenance than traditional water heaters, as they have fewer components and no storage tank to maintain.
  • Control to the Users: Anyone can easily adjust the intake of gas flow and control the rate of heating required.
