Having a constant supply of hot or boiling water is a necessity not just in most kitchens but also in hotels, buffets, offices, cafeterias and break rooms. Allow customers or employees to self-serve coffee, tea and hot chocolate. In a kitchen, quickly prepare large batches of soups, gravies, sauces, gelatin and mashed potatoes. Having regular access to hot or boiling water is also a pre-requisite to many food safety legislations. Commercial hot water dispensers are designed to run over long periods of time while constantly maintaining a set temperature. Many hot water dispensers also come with thermostat controls to help you accurately set the temperature you want your water at.
