Zip HydroBoil Classic 5 Litre Wall-Mounted Boiling Water Unit

The Zip HydroBoil Classic is a wall-mounted instant boiling water unit designed for commercial and semi-commercial settings where a reliable, on-demand hot water supply is needed without the wait associated with a conventional kettle or urn. The 5-litre capacity unit heats and holds water at just below boiling point, ready to dispense whenever it is needed throughout the day.

In practice, this type of unit works well in settings with a steady but moderate demand for hot water — think staff canteens, office catering facilities, smaller cafés, or back-of-house break areas. The unit maintains water temperature continuously, so there is no recovery delay between uses during a busy service period, provided demand stays within the capacity of the unit. For sites with high-volume or near-continuous demand, it is worth considering whether a larger-capacity unit would serve better.

From an operational standpoint, the HydroBoil Classic offers a number of practical advantages over traditional kettles or standalone urns:

• Instant boiling water without the need to monitor or re-boil
• Wall-mounted installation frees up worktop space
• External two-way tap with fingertip control for cup filling
• Tap locks on for hands-free filling of pots or larger vessels
• Enamelled steel construction is straightforward to wipe down and maintain

Installation is straightforward for a qualified plumber and electrician — the unit requires a mains cold water connection and a suitable electrical supply. Being wall-mounted, it does need a sound wall surface capable of supporting the unit's weight, and enough clearance below the tap for comfortable dispensing into cups and jugs. The compact footprint means it fits neatly into most service areas without significant disruption to the existing layout.

This unit is well suited to lower-volume commercial sites, staff welfare facilities, and hospitality back-of-house areas where consistent access to boiling water matters but peak demand is moderate. For larger kitchens or high-footfall catering operations requiring greater throughput, a higher-capacity unit would be a more appropriate choice.

If you are unsure whether the 5-litre capacity is the right match for your site's daily demand, we are happy to talk it through before you commit to a purchase.
