Water Coolers, Fountains and Hot Water Boilers,
for Offices & Call Centres

The human body is 60% comprised of water, and part of this is lost every day through natural dehydration caused by whatever working environment we occupy.

Although office workers may not be as physically-active as their blue-collar counterparts, hydration is equally important in the office environment because the brain itself comprises 75% water, and is therefore more immediately susceptible to dehydration. This is why numerous official studies have shown that proper hydration can raise our ability to concentrate, improve our cognitive performance, prevent tiredness and reduce feelings of lethargy or irritation.

The European Food Safety Authority (EFSA) recommends a daily intake of 2.5 litres of water for men and 2 litres of water for women. With our food contributing around 20% of that daily water requirement, the rest needs to be made-up within our fluid intake, showing the important contribution that drinking water can provide.

Our Recommendations For Water Boilers & Water Coolers In Offices / Call Centres

Water Coolers & Boilers for Large Offices

Working in a large air conditioned office can speed up moisture evaporation from our skin and lungs so we end up with increased water loss.

It is important that staff are encouraged to maintain hydration, and drinking water is a good choice throughout the day, as it is the zero-calorie option for fulfilling hydration requirements without affecting dietary health.

Glug Glug Glug’s mains fed Water Coolers are the ideal solution. They provide a constant supply of clean and refreshing water at convenient locations, easily accessible to all.

When meeting with potential new customers, or providing hospitality to external visitors from other organisations, it is paramount to make a good impression.

Case Study:
Benross, Weybridge

Benross make high performance golfing equipment and offer a wide range of golf clubs, clothing and accessories at affordable prices. It is one of the biggest UK Golfing Brands and is continuing to grow throughout the UK.

Requirement

Benross had a small kitchenette area to service a very busy office. They wanted to provide their staff with easily accessible drinking water and boiling water for beverage making but space was proving an issue, particularly as they were also looking to locate a new product demonstration area nearby.

Solution

We carried out a free site survey to determine which products would work best for Benross, based on the space available and the level of demand for both hot and cold water throughout the day. We recommended an under sink chiller unit with an over sink tap to provide chilled, filtered drinking water and a compact, counter top water boiler for tea and coffee making. This meant that they could remove their existing water cooler to free up more floor space and also do away with having to wait for a kettle to boil.
