How Does a Hot and Cold Water Purifier Work?
A hot and cold purifier starts working by purifying the water. If it is a multi-stage RO purifier, the unit removes dissolved salts, microbes, and germs. Then it stores the purified water in a tank. A small tank with a heating element draws from the main tank. For cold water, the unit has a compressor-cooled tank. These purifiers have a touch panel or separate taps.
For example, Rentomojo’s DriftLux features touch dispensing for ambient, warm, or cold water. It has an 8.5L storage tank and triple-layer purification for high-TDS water.
Does a Hot and Cold Purifier Cause High Electricity Usage?
Yes, a hot-and-cold water purifier has a built-in heater or water dispenser, which can increase your electricity bill. A regular water purifier uses 30-100 watts, but a hot and cold water purifier draws around 500-1,500+ watts.
Usage stays low when you use cold water. The noticeable spike mainly comes from the heating element. In winter, it is hard to turn off the warm water option. Keep the filters clean so the fan doesn’t overwork and draw extra power.
For Delhi homes: The electricity bills are likely to be high in winter. When water sits at 15°C, it takes 30% more energy to heat it to 30°C.
Hot and Cold Water Purifier vs. a Regular RO: What’s the Difference?
The compressor is the main differentiating component. A hot and cold purifier provides hot water, typically 80°C-90°C. It features an additional storage tank, heating element, and a cooling compressor. A standard RO water purifier includes only a pump, filters, and a tank.
| Feature | Hot and Cold Water Purifier | Regular RO Purifier |
| Temperature Settings | Dispenses hot (80°C–90°C), cold (15°C–20°C), and ambient water. | Dispenses only ambient (room temperature) water. |
| Extra Internal Parts | Includes heating elements, cooling compressors, and extra tanks. | Includes only a standard water pump, filters, and one tank. |
| Storage Setup | Uses separate insulated tanks (often stainless steel for hot water). | Uses a single plastic or steel tank for room temperature water. |
| Power Needs | Uses more power to keep water hot and cold all day. | Uses very little power just to run the pump during filtration. |
| Yearly Service | Costs more if the compressor or heating coil breaks down. | Costs less because it only needs regular filter changes. |
| Best Used For | Instant tea, coffee, baby formula, or quick cold drinks. | Simple, clean daily drinking water. |
Do You Need a Hot Water Purifier in Delhi?
In Delhi, the average minimum temperature is 7°C in January, 25°C in May, 27.7°C in June, and 8.4°C in December. A hot and cold RO water purifier eliminates the need for manual effort. The unit combines multi-stage RO technology and the functionality of a kettle.
The hot and cold water purifier pays off when you already need purification and the hot or cold water is an added bonus. First, decide whether you need an RO, RO+UV, or UV+UF purifier.
Does it pay off? If you use hot water several times a day, a hot water tank is useful. Drinking normal water at night in winter isn’t pleasant. The warm setting solves the problem without having to boil anything.

Which Purification Does Delhi Water Need in a Hot and Cold Water Purifier?
For a hot and cold water purifier, purification technology matters most. So, first check whether the purifier matches your water supply. According to India’s drinking water standard, IS 10500:2012, the acceptable TDS limit is 50 mg/L. Households in Delhi use Delhi Jal Board supply, borewells, and tanks; therefore, TDS levels vary by source and area.
| Source water TDS | Purification needed | Note |
| Below 500 ppm | UV + UF can be enough | UV and UF kill germs and remove particles but don’t lower TDS |
| 500–2,000 ppm | RO | DriftLux is rated to 2,000 ppm; Aquaguard Hot & Cold RO+UV to 500–2,000 ppm |
| Above 2,000 ppm | RO with pre-treatment | Above the standard’s permissible ceiling |
Hard water affects the tank the same way it does to any RO purifier. However, the heat is not likely to damage the water filters. When water passes through the RO membrane and filters at a certain temperature, it is heated in a separate tank. The filters do not come in contact with hot water.

Conclusion
In the end, a water purifier with hot and cold water works like a regular purifier. However, the hot and cold water dispenser adds a layer of convenience to the user’s life. It rejects water like other RO purifiers, so you should check the recovery rate before choosing a unit. But the most important thing is to verify your water source – borewell, tanker, or Delhi Jal Board supply. Each supply has a different TDS level, which decides whether you need an RO in the first place. How many people are in your house matters – an 8.5L tank covers around four cups before reheating. If it is a busy household, you might need a bigger size. If you are unsure about whether you are choosing the right purifier, check out Rentomojo’s range of water purifiers on rent in Delhi.
