Heating Performance

The most significant aspect that we look at when selecting the best geysers is the aspect of heating performance. We are testing a lot of things such as heating speed, heat retention, hard water resistance, and safety mechanisms.

Storage Water Heaters

The AO Smith SDS-GREEN-015 is the undoubted champion in all the heating tests regarding pure durability and hard water resistance. No other geyser matches the Havells Adonia Spin as it has a 2X corrosion resistance in all water conditions. Amazingly, the Adonia Spin performed almost the same with its Feroglas coated inner container.

The cheapest model was the Crompton Amica 15L that has a very fast heating rate of 10 minutes to 45°C. But it is also very cheap, and therefore some of that high-end experience can be forgiven.

When it comes to hard water resistance, virtually all geyser models suggested on this list were able to handle hard water. Most of the geysers scored very well and some were literally there themselves with the AO Smith and Haier Precis being particularly good.

To compare, the average storage water heater that we test has average corrosion resistance. The mean premium geyser is 1.5X to 2X corrosion resistant, according to all of our tests so far.

The performance of all the devices was excellent in heat retention and all pressure handling test was not a threat to any geyser. The same applies to the safety test where all the devices have multi-level protection.

Comparison of Energy Efficiency.

In the case of the energy efficiency test, we would like to know how the whole geyser system is energy efficient. Highly efficient geysers make sure that the electricity used is converted to heating water. Inefficient geysers can be inefficient in terms of heat loss.

To experiment with this, we will measure the amount of electricity used during heating periods and the retention of heat over a long period of time. After that, we compute the total efficiency rating according to these measurements.

All storage water heaters are tested using this test.

All the geysers recorded 5-star BEE rating, which is very efficient in terms of energy consumption. With that said, the Haier Precis was unique with its 4-day heat retention because of 25 percent thicker insulation. Another feature that impressed the Crompton Amica was the Standby Cutoff feature that used less than 1W when not in use.

Heating Speed Comparison

To measure the rate of heating of storage water heaters we fill the tank with room temperature water and time how long it takes to reach optimal bathing temperature.

This test is only conducted on storage water heaters. Instant water heaters are those that supply hot water instantly so that the time that is taken to heat water does not matter.

We tested the Usha Misty 15L, which took the shortest recorded time of 13 minutes 58 sec to 60°C. The remaining geysers were not too distant with all models having 2000W heating components to ensure consistent performance.

The average time of heating to optimal temperature in 15L capacity is 12-15 minutes, based on all of our tests so far of storage water heaters.

Safety Features Comparison

Safety is concerned with the capacity of the geyser to shield the users against electric shocks, overheating and pressure problems.

Since safety is of utmost importance to water heaters, this test is carried out widely on all storage water heaters.

Regarding safety, the Haier Precis 15L is the only geyser in this list that has a shock-proof technology that is globally leading and ensures that there is no current in water at any time. Other geysers have great safety features, but the strategy of Haier provides it with a competitive advantage in terms of protection over a larger scope. The other geysers are well protective, however, the Haier is above the industry standards.

The AO Smith is the safest when it comes to general safety measures of its shock-proof ABS outer body.

Build Quality Comparison

The life of geysers is very dependent on the materials and the way the tanks are built. Premium geysers are constructed with sophisticated coating, and the low-end products provide a reliable construction at affordable costs.

Vertical Water Heaters

Every geyser is accompanied by a collection of protective coating and construction characteristics which contribute to the durability. Premium geysers are more heavy, advanced in glass-lining and have longer warranties. In comparison, the cheaper geysers are lighter and simpler to instal, but can be of standard coating.

The following table summarises the build characteristics and specifications in terms of durability. It is important to note that there are regional variations of some of the geysers that might be of different specifications.

Usability Comparison

Storage water heater usability is concerned with the characteristics that make it more convenient to use. Such characteristics as free installation or control knobs that regulate the temperature make the user experience better.

All the suggested geysers have the ability to adjust the temperature, but the Haier Precis is the only one that has the Bacteria Proof System. With that said, all devices have rudimentary safety features.

The Crompton Amica is easy to install and has free installation. It minimises the hassle of initial setup, and the process of onboarding is easier. The same case applies to Usha Misty that incorporates pipes and free installation.

The other highlight is the Whirl Flow technology on the Usha Misty. The efficient heat distribution saves the user time and energy used in heating.
