Buyer’s Guide – What to Consider While Purchasing Geysers

Before purchasing any product, it is very crucial to understand the requirements and have proper knowledge on features – because without it, you will end up with unsuitable product and waste money as well.

The same implies for geysers as well. Below, we have gathered all the information required to analyse geysers as per your requirements.

1. Capacity to match family

This factor depends on the usage, number of people in the house, purpose and others. For instance, if you have a large family, then purchasing a geyser with higher capacity or providing hot water quickly for longer period is recommended. However, if you are a small family or just an individual, then it is better to invest in a small sized geyser.

To make things a bit easy for you, we have provided a table below representing family size, ideal capacity, type of geyser and others.

Now that you have a clear idea on which size suits your requirements, we shall further discuss of the types and other factors in the rest of the article.

2. Energy source: Electric vs Solar vs LPG Gas

Based up on the source of energy, geysers are categorized into three types – gas, electric and solar. Below we have mentioned a detailed description of each category for your knowledge.

a) Electric Water Heaters

As the name implies, these geysers consume electricity for providing hot water. Working principle of electric geysers is actually very simple – electric energy is converted into heat through heating elements to increase the temperature. Some of these appliances in the market come with smart features like time delay, requirement temperature and automation.

These water heaters are perfect for people living in apartments and rented houses. When compared to gas water heaters, electric ones can heat the water at higher temperature.

b) Gas Water Heaters

These water heaters consume natural gas like LPG (liquid Petroleum Gas) or propane gas to operate. . They have the capability of heating water quickly when compared to electric geysers.

While installing a gas water heater, it is important to fix the device behind the LPG gas cylinder in order to provide thorough gas supply through pipelines.

Most of the gas water heaters are either instant or tankless. Gas geysers are perfect for installing in the kitchen as it is where you will be placing the gas cylinder. However, if you are placing it in the bathroom, then make sure to place the cylinder outside for safety purposes. As gas cylinder emits carbon monoxide fumes, ventilation is very cruicial.

When compared to electric water heaters, the operating and maintenance costs of gas geysers are cheaper. Installation of gas geyser is a bit difficult as they occupy large space and require separate gas connection as well. And safety is a bit concern if they are not made up of high quality materials. They don’t last more than 6 – 7 years.

c) Solar Geysers

If you are living in an independent house, then solar geysers are the best choice. These machines work by absorbing heat from sun rays through roof-mounted solar panels. The energy from sun rays is converted into heat and transferred to water tank where heating is performed.

With this option, you don’t have to waste money on electricity or gas to provide hot water for the whole family. The initial cost is a bit higher than other options. However,it will pay off in the long term. Solar water heaters are not suitable for apartments and tenants.

Some of the geysers present in the market also work on gas or electricity as backup in emergency purposes. The only disadvantage of solar water heaters is – they are compatible only if you own home with open space or open terrace. Also these appliances may not be effective in winters and monsoons when sunshine is very little.

3. Instant vs storage type of geyser

If based on storage capability – water heaters are categorized into two types – storage geysers and tankless (or instant) geysers.

a) Storage water heaters

As the name suggests, storage geysers have a water tank that store the heated water for certain period of time. When you switch on the water heater, certain amount of water (based on water capacity) is heated and store. The temperature of the stored water is maintained through thermostat for certain amount of time.

Most of the water heaters present in the market have two kinds of water tanks – stainless steeland copper. Steel tanks are expensive, last longer and requires less maintenance. Copper tanks are even more costlier, however work much better.

Different models come with different capacities, you can choose based on your requirement. If your family is small, then 20-liter capacity is good enough. However, if your family is large, then 25L – 35L capacity is required.

b) Instant or tank-less geysers

Instant Geysers don’t have separate storage tank capacity like storage geysers. They will provide instant hot water whenever you need. In instant geysers, once you switch on, the water is heated quickly and delivered, and once you switch off, it will stop heat water immediately. If you want hot water again, then you have to again switch on the device. Though the name states instant, getting hot water can take a few minutes depending on the distance between heater and tap.

Comparison: Storage vs Instant geysers

4. Make of the water tank

Typically, materials used for water tank heaters are either copper, thermoplastic or stainless steel. These materials ensure efficiency and safe output.

• Copper: It is one of the most used materials to build tanks for water heaters. As copper is a good conductor of heat you can get a quick response in heating the water. However, it causes corrosion, loss of heat and regular maintenance.
• Stainless steel: Commonly used in most of the modern day water heaters, stainless steel tanks are usually coated with anti-corrosive powder and glass lining to keep the tank free from corrosion and other electrochemical reactions. The insulation is better and also requires little to no maintenance.
• Thermoplastic: A lesser known material for a tank. However, thermoplastic tanks have a better non-corrosive feature when compared to copper. On the downside, they are not insulated.

5. Water tank is anti-scale and anti-corrosive

While purchasing a geyser, it is very important to check whether the water tank has anti-corrosive and anti-scale lining. However, before that, analyze whether your water is hard or soft. In some parts of India, quality of water is extremely bad. Hard water can easily corrode and build-up calcium scales in the water tank – which can damage the heating efficiency. And you may have to replace the water heater once in a year.

To solve the corrosion problem, manufacturer’s coat the inside of the water heater tank with anti-corrosive materials. Some of them include porcelain enamel glass, glass lined, vitreous enamel, blue silicone enamel, titanium and several others.

Steel-based alloys and glass coatings provide good insulation, less corrosive, maintain original surface for longer time. Placing magnesium rods in the center can keep corrosive salts at bay. For preventing any damage, you can use water softeners – as they convert hard water to soft water.

6. Heat insulation

In order to reduce energy consumption, geysers are wrapped in heat insulation. Apart from that, insulation also speeds up the heating process and maintain operating temperature. Thicker the insulation is, lesser the heat loss will be. Geysers present in the market have different insulation ratings. However, for more effective results, you can add more layers of extra insulation outside the heater as well.

Most commonly used geyser insulation is fiber glass wool that is fixed with straps or trap. When the burner is used, the insulation should block combustion gas outflow and air flow. Some modern geysers come with PUF (polyurethane foam). They are much better than glass wool as it has the capability of retaining water temperature for a long time. This not only saves 40% energy but also the save money as well.

7. Water inflow pressure

If you own a flat or live in a multi-storied high rise building, then these apartments have high pressure pumps to ensure water reaches every flat. If the water pressure inside geyser gets too high, then it can lead to issues like leakage. The pressure in the geyser depends on pressure of tap providing the water and water expansion inside while heating. Usually, the pressure is calculated in bars.

An ideal water heater with more than 6 bars can withstand high water pressure. Any lower than that, leakages and tank bursts can be expected. Most of the modern day geysers come with a safety valve to depressurize the water within the tank by releasing some amount of water. Glass lined coated inner tank is more suitable as they will resist high pressure.

8. Heating coil

Heating element is also as important as the tank material. Most brands make copper heating elements with a coating use to prevent corrosion.  Some manufacturers use glass coated Incology heating element; they are considered to be the best in resting corrosion and the most expensive ones. They last for about 4 years with hard water source. Another popular heating element is glass coated copper heating element; they are not so expensive but are quite good. Copper coated heating element lasts for about 2 years even in hard water source areas.

9. Auto-off feature

Most of the modern water tank heaters have a smart feature – automatic shut off. Sometimes, people forget turning off the water heater. In such situations, this factor is beneficial. It helps to turn off the geyser by preventing unnecessary power consumption.

10. Power consumption

Electrical water heaters add up to 15% of your monthly electricity bill depending upon the weather conditions and consumption. Although most of the household appliances are energy efficient, it is still essential for you to understand the amount of power your water heater consumes in order to make some savings.

All the branded water heaters are BEE rated. Look at the BEE label and study the annual power consumption in units. You can then cross check that with this simple formula

Units consumed = Water volume X Temperature difference X Cost of electricity.

Other than this, there are a few factors you have to consider deciding the energy consumption of the water heater.

• Input water: The rate of heating depends of the initial water temperature which will change with season, also the power consumption.
• Purpose of water: needless to say, the purpose of water usage plays an important role in energy consumption. Large quantity of water requires more power.
• Thermostat setting: all the modern electric water heaters come with a thermostat that lets you set a temperature which is further maintains using the auto on/shut off feature.
•  Auto-off: a geyser with auto off feature shuts the device off after reaching the desired temperature which prevents unnecessary power consumption.
• Heat retention: although most of the modern heaters do come with this feature, this is a less significant feature deciding the efficiency of the product. The more the heater retains the heat, the less power it consumes.

11. Wattage needed

Usually, electric water heaters best operate at 1500-2000 watts. Some branded geysers come with increased power to 3000 watts which draws more power over a short period of time. A geyser with high flow rates (100L/hr) will draw more power than water heaters with lower flow rates

12. BEE ratings

All the water heaters are marked with a BEE star rating by the Government of India. Higher the number of stars (on a scale of 5), the more energy efficient the device is. Star rating is something one has to consider in order to save money and time on the longer run. 5-star rating geyser is more energy efficient and works on much lesser electricity than a geyser with 4-star rating. Always consider buying any home appliance with 4 or higher star rating.

13. Mount – vertical vs horizontal

Vertical mount water heaters are the most common type of heaters found in the market. Horizontal heaters called H-wall water heaters are a new entry to the market that are suitable for areas with low ceilings, false ceilings or attics. Make sure your bathroom/kitchen has about 2 feet of space to fit a vertical mount water heater.

14. Build material

Now that we know the importance of the material used in building the inner tank, let us look at the limitations set in building the outer body.  The outer body can be built using plastic. However, a sturdy material such as ABS is preferred. The plastic even helps in moulding the heater to the desired shape and design.

15. Design and aesthetics

It is always good to have some additional features like good design, adjustable knob and others to make the bathing experience even more convenient. Our body cannot handle too hot water, so you don’t require hot water that exceeds 50 degrees Celsius. That is why, it is better to have customized heat temperature adjustment in a geyser. This will prevent the struggle of mixing hot and cold water to get desirable hotness. And moreover, it saves  electricity bill as well.

16. Durability of the appliance

The durability of water heater represents the ability to withstand and function effectively even in unpleasant conditions. The durability of the geyser ensures long-lasting nature without any damage to the product. Moreover, the maintenance of the geyser depends on geyser type and frequent usage. To maintain geyser in good working condition, clean the tank once in every week to prevent from rusting.

17. After sales service

Geysers are one of the important household appliances. When you buy a new one, it is always advisable to purchase from a reputable brand which offers quick repairs and replacements in case any damage occurs.

18. Warranty period

Just like any other household appliance, warranty of a water heater is important as well. Most of the high brand geysers come with 4 to 5-years warranty on water tank and 2 to 3 years on other parts. During the warranty period, if the product doesn’t work, you can get free replacement or repair work done without paying.

19. Cost of the appliance

Though we have mentioned this factor in the last, it is equally important to others provided in the buying guide. If you’re on low-budget, go with the entry-level models that best matches with your heating or storage requirements. Otherwise, go with top-notch water geysers that come at expensive rates.

20. Additional features/tips to consider

• Electric geysers with copper tank should not be used at home with high water supply pumps as high water pressure can damage the geyser along with the tank.
• When installing a gas heater place the LPG gas cylinder up, outside of the bathroom with a proper leakage proof pipe. The gas heater emits Carbon Monoxide (CO) gas so there should be proper ventilation system.
• Your electric heaters should have an auto cut-off feature that efficiently shuts down the supply of power as and when the water reaches 60℃. Any further heating can cause internal pressure to build up and outbursts.
• Buy only those heaters that carry a genuine BIS/ISI certification. This guarantees that the product has undergone all the necessary trials and assurance checks.
• It is advisable to hire a professional to install the appliance as slight negligence might risk the life of the product and yours.
• Always check for the manufacturer’s warranty information at the time of purchasing.
• Shock proof and rustproof -ABS Plastic body
• Fire Retardant Cable: reduces the flammability of the cables to prevent any chances short circuit.
• A safety valve- to discharge excess water when the pressure or temperature exceeds safe limits.
• Auto-On/Off- to automatically turn the device off and on when needed to prevent electricity wastage.
• BEE star rating- higher the star rating more the energy savings.

Safety Measures When Using a Geyser

• Children should be stay away from geyser while it is on otherwise they can burn their hands with hot water
• Don’t use other electrical device in the bathroom when using a geyser
• Flush out the sediment build-up regularly to avoid unnecessary electricity consumption.
• Never keep geyser on for a long period of time.
• Operating at higher temperature levels causes more electricity consumption. By setting the temperature from 60 degree C to 50 degree C you can actually save 18% more electricity.
• Water heater wastes electricity when you left unused water inside the tank. Always switch the geyser on before using and switch it off when you are done.
• Most of the geysers have by-default thermostat settings at 60 degree C. Please be careful while using it as this high temperature can cause serve damage and burns to human skin. Always mix cold water with the hot water to lower down the temperature.
