Buying a water heater is not rocket science, but there are certain factors to keep in mind when investing.
- Types of water heaters:
According to your needs and convenience, you can buy a suitable water heater.
- Storage water heater (6 Litres and above):
The storage water heater is the most basic and classic form of a water heater. They are widely used for domestic purposes. It is called a storage water heater because the storage tank is installed inside the equipment. Even without electricity, it can store a lot of hot water, so it can be used when needed.
- Instant water heater (1-3 liters)
Instant water heaters are high-power appliances that can heat water immediately. These types of water heaters are very compact and are suitable for small bathrooms and kitchens with limited space.
- Solar water heater
Solar water heaters are both environmentally friendly and can achieve their goals, and also help us promote sustainable development. They use solar energy to convert renewable solar energy into heat.
- Gas water heater
Gas water heaters are water heaters that run on LPG. They are supplied via natural gas pipelines/cylinders and are highly energy efficient. They are lighter in weight and very cost-effective.
- Immersion heater rod
This aboriginal technology that uses heating rods instead of equipment is a convenient and practical way to heat water. Due to its compact size, the immersion heating rod can be easily accommodated in storage places or cabinets. It is designed for rapid heating and includes a hanging hook, a safe operation indicator, and a water level indicator. What else do you want?
6. Family size
Your daily water demand is one of the main factors that determine the capacity of the water heater. The following is a rough concept of the capacity required for general use. Please note that this is indicative, as the capacity will vary based on water usage patterns, inlet water temperature, and weather conditions.
|6-10L||2 person per bathroom|
|15L||1 – 2 person per bathroom in a cold climatic location|
|15L or more||3 – 4 person per bathroom|
|25L||3 – 4 person per bathroom in a cold climatic location|
|35L or more||More than 4 people, bathtubs|
|Instant water heater||Kitchen, mild hot water requirement|
7. Energy efficiency
Energy-saving products are good for your pocket and our environment. Therefore, it is a wise choice to use a water heater with low power consumption and high efficiency. The energy efficiency of a water heater is represented by its energy star, that is, the higher the grade, the higher the energy efficiency of the product.
8. After-sales service
Water heaters are sensitive equipment and must be taken care of and maintained regularly. In case of damage, it is very important to have good after-sales service support to repair the geyser.
9. Water type
Many people underestimate the damage caused by hard water to the water heater. Hard water contains a lot of mineral salts, such as calcium and magnesium. The minerals present in hard water can cause scale. For a while, this started to interfere with the efficiency of the water heater.
10. Pressure pump compatibility
If it is a high-rise building, you need to use a pressure pump in the water heater. Most water heaters on the market tend to leak when exposed to high-pressure water.
Who says essential appliances can’t be beautiful? The perfect water heater is an extremely efficient water heater, which can also improve the comfort of the bathroom. Therefore, when buying a high-quality water heater, you should also pay attention to your aesthetic concept.
Storage Gas VS Instant Gas
Now, it is essential to know about the features provided by storage geysers and instant geysers. Let’s discuss each of them.
- This type of geyser provides us with an instant flow of hot water. I am thus preventing time loss.
- It is available in 1 to 3 liters as of now at mostly low price ranges.
- It is compact and is ideal for washing hands, utensils, and similar other minor works.
- It provides us with a constant flow of hot water as it stores water inside.
- It is available in 6-10 liters, 10-15litres, and so on. One can buy according to the members present in his/her family. The ideal option is to choose 10-15litres geyser for 3-4 members of the family.
- It is mainly used for bathing, washing clothes and for similar other purposes. Generally, the quantity of water needed for such purposes is high in amount. So, it is recommended to purchase storage geysers instead of purchasing instant geysers.
From putting pan water onto the flame till getting heated water instantly, a water heater becomes an essential part of our daily life. In this “need for speed” experience, it is practically impossible to keep eyes on your water heater all the time just to ensure safety. So, it is better to know about the safety tips regarding water heaters before or after purchasing.
Earthing: When using any type of electric heater, make sure that the heater is properly grounded. Lack of proper grounding can cause fatal electric shock. Water and electricity usually do not mix well.
The water heater is carefully designed to cope with this combination. However, failures are common. Make sure your electric geyser or electric pole is properly grounded. In the event of a malfunction, if your skin comes into contact with metal, proper grounding may result in life or death. For electric sinkers, make sure that the bucket is made of non-conductive material. The immersion rod must not touch the barrel wall.
Venting:- Whether you have a tank water heater or tankless water heater, venting is the most critical aspect of safety. Low emissions can cause fumes and carbon monoxide to re-enter the home instead of going outside. There are different types of vent configurations. Make sure that you install a vent that suits your specific needs.
Glass-linked tank:- Whether you are purchasing a steel water tank or plastic water tank, it is necessary to look at whether the surface is glass-coated or not. Glass coated helps heat to remain inside the tank, thus increasing the efficiency of the water heater. If your tank is made up of steel, then it will also protect it from rusting.
Power on-off : Geysers usually have indicator lights to indicate when the water reaches the set temperature. Although the thermostat is responsible for the water temperature, since the geyser emits heat to the environment, keeping the heater on will cause an ON and OFF cycle. Keeping the switch on will not only increase power consumption, but also cause a lot of wear.
Eliminate fire hazards near the water heater: If you have a gas-powered water tank-type water heater, you should remove all combustibles near the water tank. Storing flammable liquids and/or materials near the indicator light is a source of disaster. Do not store jackets, skipping ropes, trash or gas cans anywhere near the water heater. All that needs to be done is a crack in the water heater or a leak of smoke, which forms a chemical reaction with these combustible substances, resulting in an explosive disaster.
Temperature control:- Every water heater has settings in it naturally warm, hot, very hot, and so on. But the most preferred temperature is near 120°C. Well, it may vary from person to person. But for the people who have thinner skin, mostly children, toddlers should provide with the water at the temperature mentioned above to protect them from being scaled. Sometimes, the burner might burn its armature due to excessive use of the heater.
That’s why it is necessary to purchase a water heater according to the members of the family. If you have 3-4 members, then a 10-15litres water heater is generally preferred.
Instant Water Heater Brands
If you are really looking for an instant water heater, then here are some of the brands that I personally recommend.

There are also other brands to check-in. I mostly preferred those brands that include safety measures for their product.
Note:- While purchasing electrical types of equipment, you should prioritize the quality and services provided by the company rather than price.
