What is a Gas Geyser?

There is a lot to learn about a Gas Geyser. Let’s start by understanding the basics for this home applianceWhat is a Gas Geyser first.

What is a gas geyser

The geyser using fire as a source for heating water is called a gas geyser. Gas geyser because a gas is used to lit the fire- it can be propane or natural gas. It comes in two types– “Storage gas geyser,” i.e., a geyser with a storage tank inside and without a storage tank, “tankless gas geyser” or “Instant Gas geyser.” The tankless gas geysers are more common in residential use in India than the storage-type gas geyser.

Gas Geyser Parts

 Next to understanding what is a Gas Geyser, let’s move to its parts:

As we know, a gas geyser comes in two different types; their parts vary slightly for their design.

Parts of a Gas Geyser

Gas-Geyser- parts
  1. The storage gas geyser chamber. The section where the burner resides is usually called the chamber. The part above the chamber is a storage container containing the inlet water. There is a provision for controlling the gas flow and a separate regulator for the desired outlet temperature.
  1.  Burner – The burner is circular; it is placed in the chamber and connected to an LPG pipe.
  1.  Flue pipe– The flue pipe connected to the combustion chamber passes through the storage tank. It routes the combustion waste into the atmosphere. The top of this flue pipe should be attached to direct the fumes out to an area away from the bathroom.
  1.  Inlet pipe – The inlet pipe is the cold water pipe coming from the municipality water storage tank. It is provided with a valve ( mostly a ball valve or sometimes gate valve) to shut the water supply off when required.
  1.  Inlet pipe shut off valve-As explained above, this valve facilitates to control the supply of inlet water to the tank.
  1.  Overflow pipe– Overflow pipe is mounted close to the top of the storage tank. It protects the tank from under the conditions of overheated water turning to steam.
  1.  A Pressure and Temperature reliving valve– This valve plays a significant role in the safety of your geyser. If the burner keeps running even after turning it off, the water may get superheated and turn into steam. The steam may develop pressure inside the geyser and, if not released, may explode the geyser. The pressure and temperature release valve auto operates at its set point( assigned by the installation technicians) and releases the extra pressure developed inside the geyser.
  1.  Drain valve– The drain valve helps to drain the water inside the storage tank when not required, or You may use it when you want to flush your geyser.
  1.  Gas inlet pipe -The gas inlet pipe transports the LPG to the burner through the regulator and thermostat.
  1. Insulation: The storage geyser consists of insulation between the storage tank and the outer body. It is a spray injected insulation which ranges from 1 1/2″ to 2 1/2″ in residential geysers. The thicker the insulation, the better is the efficiency of the geyser. One right way to check the insulation thickness is to read the efficiency data of the geyser. The buyer should always go with a higher efficiency rating. Some geysers also contain an additional season adjustment knob apart from the gas flow control and the temperature control knob on its body.
  1. In a tankless gas geyser, a copper tube is mounted around a heat exchanger connected to the inlet water pipe. The heat generated by flames heats the water inside the tube, and hot water is instantly available at the faucet.

Gas Geyser working

 The working method differs in the tank and the tankless geysers. In a storage geyser, water hits the bottom of the storage tank through the extended inlet pipe, gets heated, and rises to the top in the storage tank. The hot water rises above the cold water for its property of being lighter in weight than the cold water. The hot water travels through the outlet pipe to the faucet or other points of use.

 The heating of water takes 10 to 15 minutes to attain a temperature of 60 -70 deg centigrade. The heating time may lengthen depending on the weather condition.

 In tankless geysers, Hot water is available instantly after switching the tap onn. The water passes through the copper tubes and gets instantly heated by the flames through the heat exchanger. The size of copper tubings is usually less ( Most often 15 mm) compared to storage geyser, and the output water is also less. Also, the outlet temperature may be uneven, making it not so suitable for a shower.

Is Gas geyser safe?

 It is noteworthy to mention that wherever combustion takes place, it uses oxygen. Hence, if used in a closed bathroom, these geysers can use all the available oxygen and may lead the user to suffocate. Such situations are very hazardous, the user, due to lack of oxygen, fails to breathe normal, and sometimes cannot speak out for help. The user in this situation loses his/her life. Similar incidents took place in Bengaluru, India, in 2018, where a couple lost their life, leaving back their two daughters of 6 years and 4 years in age.

Hence if someone is using a gas a geyser, he/she needs to be extremely careful about it. If someone has a small bathroom, he/she should opt for a good substitute for gas geyser. A good alternative can be an “instant electric geyser” or an electric storage geyser coming with a horizontal tank layout.

 If you choose to install a gas geyser, make sure it has a carbon monoxide sensor installed within, to alert you of excess carbon monoxide developing in the bathroom.

Conclusion:

Understanding the basics of a gas geyser like what is a Gas Geyser, Parts of Gas Geyser, and the working of Gas geyser can only benefit the user only if he/she tempers the use of a Gas Geyser with caution. We all know its a money saving water heater but the risk associated should be taken in consideration before buying one.
