During winter, a geyser or water heater becomes essential, as it quickly and easily provides hot water, making cold days more comfortable and everyday tasks simpler—without the hassle of boiling water manually. However, for that convenience, you must choose a high-quality, safe geyser along with reliable installation and after-sales service.
A Brief History of the Geyser
The history of geysers is closely connected to the development of water-heating technology.
First Water Heater (1868):
English inventor Benjamin Waddy Maughan created the first modern water-heating device. It was called the "Geyser." This device heated water directly through a gas flame as it moved through the pipe.
Why the Name "Geyser"?
It was inspired by Iceland's natural geysers, where hot water shoots out from underground.
Electric Geyser (1889):
American inventor Edwin Ruud developed the first electric storage water heater, which laid the foundation for today's modern geysers.
Advancements in the 20th Century:
Features like thermostats, pressure control, storage tanks, and safety technologies were introduced.
Modern geysers now come with instant heating, storage types, gas systems, solar heating, and smart sensors.
Advantages of Geysers
- Instant hot water: Essential for winter or urgent needs.
- Usable all year: Useful for washing dishes, baby baths, laundry, etc.
- Instant & storage options: You can choose a small or large size based on need.
- Safe & comfortable: Modern geysers include safety features such as thermal cut-off and pressure release valves.
- Energy-efficient models: Inverter or Eco-mode geysers consume less electricity.
Disadvantages of Geysers
- Higher electricity consumption: Especially in storage geysers.
- Storage geysers take time: Takes 10–15 minutes or more to heat up.
- Installation cost: A Professional electrician or plumber may be required.
- Tank maintenance: Scale buildup over time involves cleaning.
- Space requirement: Large geysers need more wall space.
Things to Consider Before Buying a New Geyser
- Type of Geyser
There are two main types:
- A) Storage Geyser:
Heats and stores water in a tank. Suitable for families with higher water usage. More expensive.
- B) Instant Geyser:
Provides hot water instantly. Suitable for low usage and quick needs. Less effective for frequent bathroom use.
Usage Type Family Size Recommended Capacity
Basin/Wash 1–2 people 1–3L (Instant)
Bucket Bath 2–4 people 10–15L (Storage)
Shower Bath 3–5 people 15–25L (Storage)
Large Family 5+ people 25–30L (Storage)
Bar Pressure indicates the maximum water pressure a geyser can withstand.
Multi-storey Buildings: Higher water pressure → Use 8 bar or above geysers.
Single-storey Houses: Lower water pressure → 6 bar is enough.
If the pressure rating is lower than your water line pressure, the tank may leak, or internal parts may get damaged.
Higher wattage heats water faster but consumes more electricity.
Instant Geyser: 3000–4500W
Storage Geyser: 1500–2000W
- Tank Material
Tank quality determines durability.
Glass-lined or Porcelain Enamel: Best, rust-resistant, long-lasting
Stainless Steel: Good, but may rust over long-term use
Choose a geyser with:
Thermostat
Thermal cut-off
Pressure release valve
Anti-siphon protection
Minimum recommendation:
Geyser: 1–2 years
Tank: 5 years or more
