A mains-fed water cooler, sometimes called a plumbed-in or bottleless water cooler, is a dispenser connected directly to your building’s mains water supply. Rather than using large bottles, it filters water at the source to provide fresh drinking water on demand.
Mains-fed water coolers are ideal for offices, staff kitchens and breakout spaces where teams need easy access to fresh drinking water throughout the day. With no bottles to change or store, they provide a cleaner, more practical hydration solution for busy workplaces.
Because mains-fed water coolers connect directly to your mains supply, they offer a predictable way to manage workplace hydration. Businesses can avoid the ongoing logistics of bottled water and benefit from a more consistent day-to-day setup.
A mains-fed water cooler keeps water flowing automatically, with no heavy lifting, no bottle changes and no need to monitor stock levels. Once installed, it helps reduce disruption and keeps things simple for your team.
Choose from chilled, ambient, hot and sparkling water depending on the needs of your workplace. Whether you want a simple drinking water cooler or a more flexible dispenser, mains-fed models can be tailored to different spaces and teams.
