Engineered polymer or the revolutionary EPAC technology is used to ensure a corrosion-free inner tank
A geyser or a water heater is a small machine that you set up in your bathroom, kitchen, office, or water space, which heats up water for use. The average temperature needed for a hot bath is around 40- 60-degree celsius. Geysers come in different sizes. For a small family of 4 in India, a 15-25 liter water heater is usually sufficient for bathing purposes. A single person can make do with a 6-10 liter geyser too. There are also 50-liter geysers available, which are usually used in commercial buildings requiring a higher capacity for hot water.
Now let’s move on to the distinct types of geysers on the market. There is the Instant geyser, storage geyser, the solar, and the gas geyser.
Instant Geyser or Tankless Geyser
Instant geysers have a small water storage capacity of 1-3 liters of water
They have a high heating rate of 3-4.5kW
They heat small quantities of water instantaneously within 1 or 2 minutes
They consist of a small stainless steel tank that has metallic coils in it. When the geyser is switched on, the coils heat up, and water passing through the tank gets heated up instantly to a high temperature
The inbuilt safety features nowadays include latest technological advances like a protective coating over the stainless steel tank, a safety valve which lets hot water and steam drain out through an external outlet and an automatic temperature cutoff, to prevent overheating
Instant water heaters are best suited for use in kitchens or basins for washing hands or small quantities of vessels
Pros of Instant Geysers
They use less water and the water coming out of the Heater is fresh, as it does not sit in a tank, mixing with any sediments or rust
They are small and compact and blend easily into home decor. They also use less space in a small bathroom
They reduce standing losses. This is the energy wasted when unused hot water is left to cool down in a storage tank or pipe
They have a longer operating life of around 20-25 years as the inner tank is not exposed to stored water
They can provide unlimited hot water if the water is let down in a trickle. So they can be used best with a bucket storing the water continuously.
Cons on Instant Geysers
The water heater is usually not enough for a bath or shower
If the flow of water to the Heater is not constant, then water is not heated at a constant temperature.
The bathrooms should have an outdoor vent to enable drainage of excess water and steam
Instant heaters usually heat up water at instant high temperatures, so the electricity draw required is higher at 3-4.5 kW
It cannot be used simultaneously for two bathrooms or multiple purposes as the hot water gets over fast
It gives only around 3 liters of hot water at a time. You have to wait for another minute while the water heats up again
In case of no power in the house, hot water will not be available as there is no tank to store any hot water. Water heated up needs to be used immediately.
Storage Geysers or a Tank Geyser
They are larger in size and come in capacities of 3 liters and above
A storage heater basically stores water in its tank when switched on and heats water to the required temperature
It contains three main parts. The heating element, the tank, and the thermostat
The heating element may be made from metals such as copper, stainless steel, aluminum, nickel alloy, brass, etc. This element heats up when the geyser is switched on and heats up the water.
The tank is usually made of stainless steel and iis covered with an insulating material such as glass, porcelain, vitreous enamel, etc. These coatings tare given so that the inner layer is not corroded by continuous contact with water and the sediments in it
The thermostat is a device placed against the wall of the tank, encased in an insulating material. When heat temperature reaches the set level, the thermostat switches of the Heater automatically, thereby stopping the heating process. This is a safety protocol followed by every geyser manufacturer today
A pressure relief valve is also given to control the pressure caused by the heat. Drainage outlet is given to drain out the steam and excess hot water
There are also two tubes, one for bringing in cold water and one passing out hot water
Pros of Storage Geysers
They are extremely safe and can be used by anyone without fear of scalding
They can store large quantities of water and can be used for a longer period once hot water is stored in the tank
They heat slowly, so the electricity required is less. Most geysers use only around 2kW of energy compared to instant geysers
They are very budget-friendly and are easy to install
Cons of Storage Geysers
Standing loss of water that happens when heated water is left to cool in the tank is quite high
These heaters tend to reheat water, again and again, so the energy cost can be more
It takes time to heat the entire capacity of water if the Heater is a high capacity one
If you run out of hot water while taking a bath, you’ll have to wait a long time until the water heats up again.
They have a lower life expectancy of 10-15 years due to corrosion in the inner tanks. Regular maintenance and cleaning are also necessary.
While electric geysers run on electricity, gas geysers run on, well, gas.
They are fast heaters and heat water faster than the average electric geyser, but come in compact sizes like the instant geyser
The geyser has a pipeline that has a gas burner installed underneath. When water passes through the pipe, the burner ignites and heats pipe which in turn heats the water
The mechanism starts when you open the tap of water and shuts when you close the tap. There is no electricity involved
Pros of Gas Geysers
They are quite efficient and use less energy in terms of gas
They are very compact as there is no need for storing water
They can be used in times when there is no power and are not subject to voltage fluctuations
They are speedy to heat water compared to electric storage heaters
The heating element uses high energy equivalent to 12 kW
They require space in the bathroom as an outdoor vent is required. In fact, gas geysers should never be installed in a completely closed space
They should be kept away from any other electric equipment, wiring, and corrosive material
Since gas is used, it is necessary to keep refueling the LPG and checking the flame while using the Heater
These geysers are usually installed on the roofs of buildings and use solar energy to power the heating process
They are available in larger capacity tanks from 100 to 350 liters.
The Heater is connected to solar panels which convert sunlight into solar energy
The heated water can be stored in an insulated tank
Two types of solar heaters are available in the Indian market: the metallic FPC system. The other one is an ETC system, which is made of glass.
Solar heaters save on electricity costs as they use the suns rays to generate hot water
They can provide hot water without any electrical wiring and work when there is no power
They use green energy
They have high maintenance costs as the exterior of the tanks can get corroded, due to being in the outdoors
Solar panels also need regular maintenance
A sizeable area is required on the terrace for installation
On overcast and rainy days, heating may not happen
Instant Electric heaters and storage heaters are the ones that are used in most homes in India. Solar heaters are slowly gaining ground with high rise buildings who want to reduce electricity costs. But gas geysers are not used much, due to their inherent safety concerns.
