A water heater is called geyser in most of India, is an essential device used to heat water for various household needs like bathing, washing dishes, and other important tasks. In India, geysers are particularly popular due to the need for hot water during winters when water temperature is too low common uses.

Water Geysers are available in different uses and needs in India:
  1. Instant Water Heaters: These geysers heat water instantly as it flows through the unit. They are compact and suitable for small households or locations with limited space.
  2. Storage Water Heaters: These geysers come with an insulated tank that stores and heats the water. They can provide a continuous supply of hot water for an extended period, making them suitable for larger households.
  3. Gas Water Heaters: These geysers use LPG (liquefied petroleum gas) as the fuel source for heating water. They are energy-efficient and work even during power outages, making them popular in areas with unreliable electricity supply.
  4. Solar Water Heaters: Solar geysers use solar energy to heat water and are eco-friendly and cost-effective in the long run. They are more prevalent in areas with abundant sunlight.
