Which Clearwater water cooler is better to choose — sparkling or still?

What is the difference between a pump and a dispenser for Clearwater water, and which option is better to choose?

A pump and a dispenser are two simple and economical ways to use CLEARWATER each with its own advantages and disadvantages.

The pump is placed on the neck of the bottle after removing the cap and dispenses water at room temperature. It can be mechanical, where water is obtained by pressing the top of the pump, or electric, with automatic dispensing via a button. The main advantage of the pump is that the bottle does not need to be inverted, and the device requires less frequent cleaning. The downside is that pumping the water requires effort, which can make it difficult for children to use, and as the water level decreases, the process becomes even harder.

The dispenser is a ceramic or plastic-ceramic container onto which an inverted bottle with an open cap is placed. Water is dispensed through a tap, allowing it to be poured in small portions or into larger containers by holding the lever. The advantage of the dispenser is that it is very easy to pour water, but installing a full 19-kg bottle requires strength and dexterity. In addition, contact of the water with air increases the likelihood of microbes and biofilm formation, so the inner walls of the dispenser should be washed every two weeks, and any remaining water should be emptied.

The pump is convenient for use in offices or small spaces for quick access to water, while the dispenser is better suited for home use, where convenient pouring and an aesthetic appearance are important.

What is the difference between mini-cooler and the standard one?

A mini cooler, or desktop cooler, is placed on a stand, table, or cabinet. Most often, it uses electronic cooling, which operates almost silently since it does not have a compressor. The downside of this type of cooling is that the water chills more slowly, so a mini cooler is recommended for 3–5 users, with a capacity of about 1 liter per hour (5–6 glasses).

A mini cooler with compressor cooling differs from a regular cooler only in size, retaining full functionality.

How much energy consumes cooler?

The cooler operates in an intermittent mode, meaning most of the energy is used during heating or cooling of the water. If water consumption is low, the cooler only maintains the desired temperature using sensors that automatically turn the heating or cooling on and off, so energy usage is minimal. With active use, when water needs to be frequently cooled or heated, electricity consumption increases.
Average energy consumption is about 1–1.5 kWh per day.

What is the temperature of heating and cooling of cooler?

The cooler heats water to 85–92 °C and cools it to 5–15 °C, depending on the type of cooler. Compressor coolers typically chill water to 5–10 °C, while electronically cooled coolers reach 8–15 °C.
It should be noted that the cooler has a certain heating and cooling capacity, which depends on the ambient temperature and determines how much hot or cold water can be obtained per hour. Cooling capacity (water below 12 °C):
at +21 °C — 4.8 L/h
at +27 °C — 3.5 L/h
at +32 °C — 1.8 L/h
at +38 °C — 1 L/h

Heating capacity (above 85 °C): no more than 5–6 L of hot water per hour.

How much water is in the tanks of hot and cold water?

Do I need to turn off the cooler at night, on weekends, on vacation?

Turning off the cooler at night or on weekends is only recommended for saving electricity. For this, it is advisable to use a special PowerDown timer, which allows the cooler to be automatically switched on and off at the desired times. From a safety perspective, leaving the cooler on overnight or over the weekend does not pose more risk than a refrigerator.

Turning it off for a longer period (one week or more) is not recommended, as bacteria can quickly multiply in room-temperature water, which may lead to unpleasant odors or taste. In this case, several options are possible:
• leave the cooler turned on;
• use the PowerDown timer and set a minimal number of operating hours;
• drain the water from the tanks after turning off the cooler: cold water through the tap, hot water through the drain hole on the back panel;
• after a prolonged shutdown, the cooler can be sent to us for sanitary cleaning before use.

How does the CLEARWATER perform sanitary cleaning of coolers?

Sanitary cleaning of coolers is carried out in several stages. External parts that do not come into contact with water are cleaned with chlorine-free household detergents — TM NovaClean IND C102. Components that contact water are treated with special chemical agents based on natural minerals — TM NovaClean IND N101 (a neutral foaming cleaning agent for manual washing of equipment containers).
After this, each cooler is disinfected with a NovaClean IND M108 solution and flushed with purified water to ensure complete safety and cleanliness before reuse.

Does cooler clean water?

Does cooler boil the water?

No, the cooler does not boil water; it only heats it to 85–92 °C, which is sufficient for brewing tea, coffee, or preparing quick meals. Boiling is necessary to kill bacteria and remove temporary water hardness that causes scale. CLEARWATER does not require this, as it is pre-sterilized and microbiologically monitored, and its hardness is low, so no scale forms.
Because it does not boil water, the cooler can be safely used only with bottled water, not tap or well water.

Why might the water in the cooler not reach the maximum temperature?

The cooler heats water to 85–92 °C — a temperature sufficient for brewing tea, instant coffee, or preparing quick meals. If more than 5 people fill water consecutively, the temperature of the last glass may be slightly lower. In this case, it is recommended to wait a few minutes for the cooler to reheat the water, or, if needed, to order an additional cooler.

If a higher temperature closer to boiling is required for certain drinks, it is recommended to use additional equipment, such as a kettle or Turkish coffee pot. If the water clearly does not heat and remains only warm, you should contact customer support for inspection and servicing of the cooler at the company’s service workshop.

How long does the gas cylinder last in a sparkling water cooler?

The sparkling water cooler is equipped with a 3 kg carbon dioxide (CO2) cylinder. Each serving of sparkling water contains about 2 g of CO2, so one cylinder is enough for 1,000–1,500 servings, or about 200 L of sparkling water (approximately 10 bottles).

For example, if there are 5 people in an office and each drinks 2 glasses of sparkling water per day (0.4 L per person), daily consumption is 2 L. At this rate, the cylinder will last approximately 100 days, or nearly 4–5 months assuming 22 working days per month.

How many people is a cooler designed to serve based on its capacity?

The cooler’s capacity depends on the amount of water consumed for beverages. For a large floor-standing cooler, one serving of tea (200 ml) is enough for 3–5 people, while a serving of coffee (100 ml) serves 6–8 people.

A mini cooler is designed for fewer users: tea — 2 people, coffee — 3–4 people. Therefore, the choice of cooler should be made based on the number of people and the frequency of hot beverage consumption.
