Both our bottled and plubed-in water coolers come with two taps, but clearly when buying a cooler you want one of these to give you chilled water - there's no debate there! However, for the second tap you have an option:
Hot - like a conventional hot tap but hotter. Ideal for cups of tea or coffee
Ambient - the water is neither chilled nor heated. Whilst not for everyone, drinking ambient temperature water has been proven to rehydrate your body quicker than chilled or hot water.
Having the hot option is slightly more expensive and if you are working to a budget you also need to consider the additional electricity costs.
