If you’re like most homeowners, you want to find the best possible way to take care of your home and family. That means making sure that you have the best appliances, products, and tools for the job. So if you’re looking for a new geyser, it’s essential to know which one is right for your needs. Here are 25 tips to help identify the best geyser for hard water. Happy shopping!

1) Geysers with more holes boil water faster and have a good flow. Geysers with fewer holes are slow in boiling and have low flow. If you have hard water, avoid geysers having small no. of jams as they will not filter out the calcium deposits.

2) Geysers with higher wattage generally boil faster and have an excellent flow than those with lower wattage. In the case of challenging water areas, it is better to buy geysers with higher watts as they will filter out the Calcium deposits and serve you for a longer duration.

3) Ensure an air gap is provided in the tap fitting to prevent scale formation. Typically, Geyser manufacturers provide an Air Gap between hot & cold water mix, which prevents the formation of limescale and provides an uninterrupted supply of hot water. If this gap is not provided, limescale will clog the Hot Water pipes causing frequent breakdowns.

4) It is better to go for a geyser with a pre-installed heat exchanger as it will provide limited scale formation. The heat exchanger works by heating the water quickly without letting calcium deposits settle down on the internal surfaces of the geyser. Heat exchangers are primarily used in Solar water heater systems but are available as separate components too.

5) When you come across a manufacturer who claims certain minerals or additives that dissolve limescale, take it with a pinch of salt. If all these minerals were adequate, manufacturers would have added them inside the tank. They only make tall claims since they know customers don’t bother to verify their authenticity!

6) Geysers made from stainless steel do not form much limescale. They are expensive but provide uninterrupted service for long years without frequent breakdowns.

7) Geysers with lower wattage are designed in such a way that they increase the boiling time, which is not at all advisable in areas where water is very hard. Hence, if possible, while buying a geyser, go for one having higher wattage to ensure proper geyser service even in challenging water areas.

8) A good quality flat bottomed geyser will give you better results than an ordinary cylindrical one. Flat bottomed geysers ensure even heating of water & prevent limescale formation on its base surface. Thus, it can heat a more extensive water capacity without much heat during the boiled-off period. Flat bottomed geysers also provide a better flow as compared to cylindrical ones.

9) Due to the fast rate of heat loss in cold water areas, geysers with tanks placed at higher levels generally have a lesser life. In the case of the low-temperature regions, it’s better to buy a geyser having copper coils immersed inside the tank placed at a lower level making sure that heating elements do not touch the tank’s base. This will ensure that more hot water is available during peak hours, even when the ambient temperature is low.

10) Ensure a thermostat is provided on your floor standing geyser that senses atmospheric temp and shuts off the electrical supply if it reaches setpoint or boiling point.

11) If you are replacing an existing geyser, get your plumber to open the old geyser and check for calcium deposits inside. This will save you from future problems due to calcification of internal surfaces of tank & heat exchanger.

12) Before buying a new Geyser, get it duly checked by a reputed local laboratory so that you can be aware of quality standards followed in manufacturing. If possible, go for lab testing at one or two places before making the final purchase.

13) Always ask the service engineer about the nature, intensity & frequency of limescale formation in challenging water areas where they will install your geyser. This will help in choosing a better geyser that will give uninterrupted service.

14) While buying a geyser, it will be a good idea to go for one with pre-installed thermal cut out & pressure relief. This will help avoid frequent breakdowns resulting from high water pressure due to complex water problems. In the case of flat bottomed geysers, it will be better to have a separate safety valve provided at the topmost point, which further relieves the pressure.

15) Using flush valves can also reduce limescale formation inside your geyser as they release many impurities present in water. But care must be taken that flush valves should not flow back into the tank. If flow before is observed, a proper air gap between the suction line and flow line must be there.

16) Before buying a new geyser, go through all these points and ask the vendor or plumber to explain their usefulness. It will help you in selecting a good-quality geyser.

17) If the existing geyser has a pressure relief valve, buy one with a similar rating & consult your plumber well in advance before purchasing the same.

18) High capacity geysers are condensing types where water is not boiled off entirely during the boiling cycle; instead, it circulates inside the compressor to cool down the entire system. Hot air is produced during the heating cycle, which further heats the water. After achieving the desired temperature, the compressor stops working, resulting in savings of around 50% on energy consumption compared to regular VRV/SHVR based geysers currently used everywhere.

19) When selecting a new geyser, ensure it has a high wattage rating for quick heating and a low amperage rating for a better economy. A geyser having a high wattage rating for fast heating is a must in the case of challenging water areas.

20) Never mix up the factory setting of electrical pressure with city supply pressure, or you will have to face frequent breakdowns. If your plumber sets factory pressure value wrongly, then the time will come when the compressor starts overheating, resulting in damage either to it or to its surroundings.

21) In challenging water areas, it’s better to buy flat bottomed geysers with copper coils immersed inside the tank placed at a lower level making sure that heating elements do not touch the tank’s base. This will ensure a sufficient amount of hot water during peak hours, even when the a low ambient temperature.

22) A good-quality geyser should have separate high-power heating elements for heating and boiling needs. This will prolong your geyser’s service life, resulting in savings on your hard-earned money.

23) In the case of SHVR type geysers, it’s good to have a pre-installed thermostat, or else it can be added later. Still, care must be taken that the heater should not get overheated due to high ambient temperature, leading to reduced life of insulation & motor.

24) A good-quality geyser should not require regular maintenance if appropriately used. Good manufacturers provide one year warranty on insulators & 5 years warranty on heat exchangers considering the age-old technology involved in their manufacturing.

25) Instead of buying new gear, you can add some antimicrobial additives inside your geyser regularly. This will clean the limescale deposits inside your geyser, which you can see & remove by yourself. Note that this method does not require the dismantling of your geyser-like in case of replacement or repair.
