What water cooler should I choose?

There are two (2) forms of water heaters: table top (to be placed on a table or counter) and freestanding (to be placed on the floor). These bottle water heaters will require a 3 or 5 gallon water bottle put on top to dispense water or may be used together with our NEW water filtration system for water heaters. What to consider would be the features like desirable water temperature and/or child lock onto the hot water dispenser. Some components have just 2 (2) temperatures (cold and hot) and many others also have room temperature. The kid lock isn't available on all components (please consult with the product specification of each version).

How can it warm the water?

The water is heated using a gas heater located inside the stainless steel tank.

How does it create cold water?

Each of the components have a cooling compressor employing an eco-friendly refrigerant.

Is the water hot enough for tea, coffee, and soup?

Yes. The water from these dispensers can achieve approx. 90 C / 194 F. That is hot enough for any hot drink like coffee, hot chocolate, soup and tea.

What filtration process is used?

The units operate with bottled water, which is already filtered from the water shipping support (please examine with your water supplier the filtered states of the water delivery), or with all our NEW water filtration system. This innovative water filter option works without the bother of bottle shipping support and gets rid of the heavy lifting involved in placing a brand new bottle every moment. Just refill with tap water and your completed!
