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
Did you know the Aquaguard Blaze Water Purifier can remove 70% of iron and deliver water with 0.03 mg/L of iron from 0.1 mg/L of input? This flagship model doesn’t stop there—it can dispense hot water at 80°C in 7.2 minutes and maintain the temperature within ±1°C for 4 hours. With its sleek design, dual temperature dispensing and advanced chlorine removal, the Aquaguard Blaze is purity and convenience in every drop.
The Aquaguard Blaze Hot and Ambient Water Purifier being a flagship product had to meet high standards and it exceeded.
The water purifier is rated for 0.1 mg/L of iron reduction and was tested with 0.1 mg/L of iron input water. The test results showed output water with 0.03 mg/L of iron, 70% reduction of iron. The system removed iron effectively but the test condition was 80% of the purifier’s maximum iron handling capacity.
This purifier has dual temperature dispensing. The tap below the red LED dial indicator dispenses hot water at 80°C, it reached 80°C in 7.2 minutes from 24°C. This is within the reviewer’s claim of 8 minutes to reach 80°C. The heating rate was consistent across multiple trials, it rose 7°C per minute. The unit maintained the target temperature within ±1°C for 4 hours after reaching 80°C. The other tap next to the hot water tap dispenses ambient or room temperature water. The black exterior has a modern minimalist design with a circular chrome control dial and digital interface with LED indicators showing operational status in red, blue and green. It has a compact wall-mountable design and high-grade ABS plastic body. The drip tray at the bottom collects spillage over a steel grating.
The water purifier removes chlorine from water as tested under specific condition. The brand claims to handle 0.2 mg/L of chlorine in input water. During testing, 0.2 mg/L of chlorine input water was purified, post treatment analysis showed non detectable chlorine (<0.1 mg/L) in the filtered water. This means the purifier can remove all detectable chlorine from water, meets its maximum chlorine removal capacity.

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 Usage A 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).
