Water Heater or Geyser buying made easy

Be it the cold winter season, when the mere thought of putting your fingers under the tap makes you cringe, or the summer season, when you like to take the chill out of a cold shower, warm water is always welcome at home. For this reason a water heater or a geyser is an essential in most homes these days.
You may have moved into a new house, or may be looking to replace your old geyser, but if you’re on the lookout for a brand new water heater, you’re at the right place. Here’s a guide packed with all the information you will need to help you make a choice and bring the best geyser back home.

Types of Geysers

There are primarily, two types of geysers available in the market in India.
Storage (With Tank): This is the more common type of water heater seen in households. The essential differentiating factor is that these geysers come with an insulated storage tank, within which water is heated and stored. A pipe, attached to the tank, carries the heated water to your taps. Because multiple liters of hot water are available at any point of time, this type of geyser works well for families that require plenty of hot water for multiple uses.

Instant: An instant geyser does not store water within itself, but heats the water using a heating element as the water passes through it. As a result, the flow of hot water is limited as compared to a storage tank geyser. However, these geysers are more energy-efficient and work well for one to two people, as long as water is being drawn from only one tap at a time.

Source of Power

Another major differentiator between the geysers available in the market is the source of power you plan to use.
Electricity: This is the most common source of power for geysers at homes these days. If you’re going for a large sized storage tank type of water heater, you would probably want to rely on electricity as a source of power to run your geyser.
Gas: Gas-based geysers typically use less energy and hence, help save on your electricity bills. However, these are best used with tankless or instant geysers. It is ideal to get a gas model if you’re buying a geyser for the kitchen, as that is where your gas cylinder is likely to be located in any case. If it is being used for the bathroom, it is safest to place the gas cylinder outside the bathroom as gas water heaters emit carbon monoxide fumes, and hence require effective ventilation.

Solar heater for green energy
Solar: You may want to look for solar water geysers if your consumption is high. They would save on your power bills but initial investment of such appliances is expensive. Also keep in mind that solar-based heaters would not be very effective in winters and monsoons when sunshine is less.

Things to Consider

Apart from selecting the type of geyser and determining the source of power you plan to tap, the following are factors to consider while making your decision.
Determined in liters, the capacity of a geyser indicates how much hot water the appliance is able to provide at a time. In the case of a storage tank geyser, the capacity will indicate the storage space within the tank. For an instant geyser, the capacity will indicate how many liters of hot water can emerge from the geyser per minute. For instance, an instant water heater of 1 liter capacity would give 1 liter hot water per minute.
To determine the capacity of the water heater you’re buying, you would need to estimate the usage of hot water at the peak hour of consumption in your household. That is, how much hot water you are likely to use at the time of the day when everyone in the family is getting ready to leave, when utensils and clothes are being washed etc.
Each geyser comes with information about its dimensions and weight. You would need to plan in advance to understand where in the house the geyser will be placed, how much space it will occupy and whether it will be mounted vertically or horizontally.
While an unbranded geyser may cost you less, keep in mind that you may end up compromising on safety. We suggest that you look for a known brand with an ISI mark or BIS certification or BEE energy star rating.
The warranty that comes with a product is another indicator of its reliability and durability. Look for maximum possible warranty and enquire about servicing as well as availability of parts of the particular brand you’re picking up beforehand.
Power Consumption
Power consumption by water heaters can amount to nearly 20 percent of a home’s energy bills. You would want to enquire how much power the heating element of your shortlisted geyser consumes to do its job.
Tank Insulation
The material of the geyser tank, both on the inside and the outside, is an important consideration as it determines the durability of your appliance. Glass lining or steel lining are common on the inside, and are reliable as they can endure high pressure. If you live in an area where water is saline or corrosive, you may want to pick up a heater with copper setup inside as copper has anti-corrosive features.
Other Features
Any additional features, over and above the ones mentioned above, would be good to have. For instance, models these days may come with external adjustable thermostats, power on indicators and temperature indicators. Devices with 2-in-1 pressure cum release valves ensure that positive and negative pressure is not created inside the tank. You would also do well to enquire about safety features in the model, like over-heating or over-pressure indicators and automatic cut offs.

With the criteria above as your checklist, you can rest assured you would be looking into all critical factors while making your purchase. At Conzumr.com, we’d love to hear from you about which brand and model you finally pick-up, in the comments below.
