Geysers are very important appliances, especially in cities where temperatures fall really low monsoons and winters. You can use geysers to heat water for your bath, to clean utensils, wash clothes, fomentation purposes and many more. Having a geyser greatly helps save on precious LPG, which is a non-renewable resource, for heating water.
Buying geysers can be quite confusing, especially for first-timers. There are so many things that you need to look out for. Capacity, heating mechanism, body material, safety coating, rated pressure, wattage – there are literally so many criteria that must be kept in mind for buying a good quality geyser that will suit your home. If you are feeling hopeless regarding how to do it, don’t worry. This guide will take you through each step so you can either choose a geyser for yourself on your own, or pick one from the list of the most popular models in India that we have provided.

Water Heater/Geyser Buying Guide
The following points must be kept in mind when buying a new geyser:
Capacity
This is the first and most obvious characteristic everybody looks for. The capacity of a geyser is noted in litres and depends on a lot of factors. If you bath using showers, it will require a greater capacity than for bathing using buckets. If your only purpose is to clean utensils or hand-wash clothes, you will need the least capacity while machine washing requires greater capacity than all this. Bathing in tubs require maximum capacity. Greater the number of members in your family, greater the capacity required. For all the above factors constant, storage geysers should be of greater capacity than instant geysers.
Heating Mechanism
Geysers can be of two types – gas heaters and electric geysers. Gas geysers use commercial gases like LPG or propane to heat the water, so it is most suitable for those who have a piped gas connection. Not only does it heat the water faster, but also does so at half the cost. They are larger in size to accommodate a ventilation system for the combustion of the gas. On the other hand, electric geysers are more popular because they can produce much larger temperatures and cost less to buy. They are smaller, safer, more efficient and environment-friendly than gas geysers. They are also easier to use and maintain. There are also solar geysers, that will be costly to install but is more economical in the long run since there will be no electricity consumption.
Electric Geyser Type
Within electric geysers themselves, there are two types. Storage geysers heat water to a higher temperature and store it in an insulated container for prolonged use. They have higher capacity due to the storage necessity, and take longer to heat up the water, which is around five minutes. Whereas, instant geysers heat water up as fast as one minute and dispense it instantly, so there is no need to store it. Storage geysers are more useful to larger families in cold, inland regions, while instant geysers are more suitable for smaller families in areas with moderate temperatures.
Wattage
Higher the wattage of the geyser, faster the water will heat and more the electricity will be saved. It will also save water since water will be heated at the time of heating only.
Material of Geyser
Since the main aim of the geyser is to heat water, the body should be a good conductor and also provide insulation against the escape of the heat. Copper heats up quickly but is not very resistant to corrosion. Stainless steel is a good heat conductor and also provides good heat insulation. Thermoplastic provides average insulation but is greatly corrosion-resistant. The coating material is also an important factor. Glassline coating provides improved insulation, but is more prone to damage with long use, while vitreous enamel coating is corrosion resistant and also prevents scaling due to hard water. The heating element should also be coated with protective material to prevent scaling and corrosion.
Pressure Rating
This refers to the maximum pressure that the geyser tank can tolerate and is measured in bars. Individual houses with less number of floors do well with low rated pressure geysers, while high-rise buildings require higher rated pressure. It also depends on the force of water in the inlet tap and the maximum temperature that the geyser provides, which affects the expansion of water and production of steam.
Mount
Geysers can be vertical or horizontal depending on the mount. Vertical or V-wall geysers are more convenient and widely used due to greater energy efficiency and lower cost. But horizontal or H-wall geysers are better for houses with low or false ceilings.
