Maestro Pressure Coolers – Frequently Asked Questions

Q – Do I need to have a mains water supply right beside where I want my watercooler to be?

A – No, as long as there is a mains water pipe (not from a tank) in the general vicinity the watercooler can be installed.

Q – How complicated is it to install a watercooler?

A – It is a minor plumbing job to connect to the mains water pipe, and run the microbore tube from the pipe through a filter either internal to the cooler or wall mounted and then on to the cooler itself.

Q – What do your filters do?

A – Our filters use activated carbon to take out chlorine and any particulate impurities in the water down to 1 micron size. They will also reduce the limescale hardness in the water

Q – How hot is the hot water from your coolers?

A – The hot tap is designed to make tea, coffee, soups etc. In most watercoolers it cannot actually be dispensed at boiling point (100 degrees) because problems would occur with steam generation inside the hot tank, so the normal temperature is about 90 degrees

Q – What are the environmental implications of a Point of Use watercooler?

A – There are significant environmental advantages of a mains connected watercooler as compared to a bottle water cooler. There are estimated to be about 700,000 water coolers round the country of which about 190,000 are mains connected units and the rest are bottle coolers (source: Zenith International West European Watercooler markets 2007). There are now over one thousand delivery trucks making deliveries of bottles to watercoolers all round Britain. This has a significant negative environmental impact both in terms of pollution and congestion. In addition the POU has the advantage that no plastics are necessary for bottles. Electrical consumption is dependant on usage, but a typical cold and ambient watercooler in an office will use about half of one kilowatt hour per day whilst a hot and cold cooler might use about 1 KWh per day.

Q – What is the EPDWA?

A – This is the European Drinking Water Association. It is the largest water cooler association and we are founder members of it.

In 2010 it changed its name, it was previously known as the EPDWA.It sets out a code of practice to which its members must adhere to cover issues of hygiene, staff training, standards of equipment and installation and other matters. All members are audited by an external auditor annually to ensure that standards are met and maintained.
