Hot or cold water dispensers are popular features nowadays in offices, staff kitchens and waiting rooms around the world. They’re also perfectly suitable for domestic use. To be sure to get the best from your water cooler, and to choose the perfect solution corresponding to your needs, here are a few facts about how a water cooler works.

There are two main categories of water coolers: bottled water units , or plumbed-in systems . Bottled water dispensers need to be plugged into an electric socket, and they can supply room-temperature, cold or hot water from standard size bottles: 10, 12, 15 and 19 litres, which are filled with filtered water. Water bottles can be delivered to your door by the company supplying the dispensers.

Plumbed-in systems are connected to the mains water supply as well as to an electric socket, and offer the same service as their bottled water counterparts. As they use municipal water, they should always come with a filtration system  to prevent limescale build-up, and to eliminate bacteria, chemicals or chlorine taste. Water is cooled or heated thanks to an electric generator, and stored into separate tanks. It is dispensed at the turn of a handle or the push of a button.

Water dispensers are generally simple machines, which will fulfill their task seamlessly if they’re used and maintained properly. There are a number of factors to consider before purchasing a water cooler, among them cost  and water quality. Compare models and prices by asking for a quote  to precisely define which water cooler will suit your needs.
