Water heaters, commonly known as geysers in India, are widely used to provide hot water for various domestic purposes. Geysers are especially popular in regions with cold weather, as they offer a convenient way to get hot water for bathing, washing dishes, and other everyday tasks.

In India, you can find various types of water heaters or geysers, including:

  1. Instant Water Heaters: These geysers heat the water on-demand, providing hot water almost instantly. They are suitable for small households or places with limited space.
  2. Storage Water Heaters: These geysers come with a storage tank to hold heated water. They heat the water and store it for later use. They are available in different storage capacities to suit varying household needs.
  3. Gas Geysers: Gas geysers use LPG (liquefied petroleum gas) as a fuel source to heat water. They are common in areas with inconsistent electricity supply or where gas connections are readily available.
  4. Electric Geysers: Electric geysers are powered by electricity and are prevalent in urban households with a stable power supply.
  5. Solar Water Heaters: Solar geysers use solar energy to heat water. They are an eco-friendly option and are gaining popularity due to their energy-saving features.

When buying a water heater or geyser in India, consider the following factors:

  • Capacity: Choose a capacity that meets your household’s hot water requirements. It depends on the number of people using hot water and the intended use.
  • Energy Efficiency: Look for energy-efficient models to reduce electricity or gas consumption and save on utility bills.
  • Brand and Warranty: Opt for reputable brands with good customer reviews and warranty coverage.
  • Safety Features: Ensure the geyser has safety features like thermostat control, auto-cut off, and pressure release valves to prevent accidents.
