Providing hot water for drinking can often be challenging during the winter months, particularly if there are senior citizens in your household. Use of boiling water on a stove is not only tiring but also time-consuming. This is where a hot and cold water purifier comes in handy, not only for the comfort but more so for hygienic reasons. The availability of purified water at the right temperature for drinking or even a cup of tea, then what you are taking is clean in terms of quality. Current popular brand names such as Aquaguard, AO Smith, and Cuckoo come with features such as temperature controls, touch sensors, and alkaline settings. In this article, I have picked some of the best Hot and Cold water purifiers along with verifying the important features such as purification technology, hot water storage capacity, safety features, and sleek product designs.
List of the Best Hot and Cold Water Purifier in India
If you’ve ever considered buying a water purifier, Aquaguard probably came to mind.

Hot Water Storage option in Water Purifier: 1 Litre Vs 10 Litre in Stainless
When considering hot water storage options in water purifiers, the choice between a 1-litre and a 10-litre stainless steel tank can significantly impact usability and efficiency. Storage Capacity and UsageA 1-litre tank is ideal for individuals or small households. It provides quick access to hot water for tasks like making tea or instant meals. However, it may require frequent refilling, especially during peak usage times. In contrast, a 10-litre tank accommodates larger families or more extensive needs, allowing multiple users to access hot water simultaneously without delays. Efficiency and Heating TimeThe heating time also varies between these options. A 1-litre purifier typically heats water faster, taking about 5-10 minutes to reach desired temperatures. Meanwhile, a 10-litre unit may take longer, around 15-30 minutes, but retains heat longer due to its larger volume.
| Feature | 1 Litre Purifier | 10 Litre Purifier |
|---|---|---|
| Heating Time | 5-10 minutes | 15-30 minutes |
| Ideal Users | 1-2 persons | 4-6 persons |
| Refilling Needs | Frequent | Less frequent |

Frequently Asked Questions
Hot water typically exhibits higher TDS levels compared to cold water. This phenomenon is primarily due to the increased solubility of minerals at elevated temperatures. As water heats up, its ability to dissolve minerals like calcium and magnesium enhances, leading to a higher concentration of dissolved solids.
Key Factors Influencing TDS in Hot Water:
Statistical Observations: In various tests, hot water samples showed TDS levels ranging from 122 ppm to 180 ppm, while cold samples often registered lower, around 90 ppm to 120 ppm (Source: fishlore.com).
Temperature Effect: The conductivity of water rises with temperature. For instance, a TDS meter may show readings such as 140 ppm for hot water and only 60 ppm for cold water from the same source. This difference arises because the meter measures the electrical conductivity, which increases as water warms up due to more active ions (Source: .
Mineral Dissolution: Hot water can dissolve mineral buildups in pipes and fixtures more effectively than cold water. This can lead to higher TDS readings, especially in systems with significant mineral deposits(Bisleri.com).
