Instanta WMS5 5 Litre Wall Mounted Auto-Fill Water Boiler

The Instanta WMS5 is a wall-mounted, auto-fill water boiler with a 5-litre tank, designed for continuous hot water provision in commercial settings. It connects directly to the mains cold water supply, refills automatically, and holds water at temperature ready for immediate dispensing through a single tap. There are no manual refilling routines and no wait between draws — it simply keeps hot water available throughout the working day.

In smaller service environments — a café, a hotel servery, an office kitchen, a staff canteen — this kind of unit replaces the kettle entirely and removes the bottleneck that comes with manual boiling. The auto-fill function means staff are not interrupted to refill a tank, and because the unit holds temperature constantly, there is no recovery delay between cups. At this capacity, it performs well where demand is consistent and moderate rather than high-volume or highly concurrent.

Day-to-day operational advantages include:

• Wall-mounted design keeps worktops and counters clear for other tasks
• Auto-fill eliminates manual refilling and frees up staff attention
• Single non-drip tap gives controlled, clean dispensing with minimal spillage
• Stainless steel construction is easy to wipe down and maintain hygienically
• Constant-temperature holding means hot water is available without waiting

Installation requires a mains cold water connection and an electrical supply. Whilst the unit can operate from a 13-amp socket, a hardwired connection is generally the preferred approach in commercial settings for both reliability and compliance purposes. The wall fixings need to be appropriate for the weight of the unit when full, so it is worth confirming wall construction before installation. Position it at a practical dispensing height with access to both the water feed and the electrical connection.

The WMS5 is well suited to smaller cafés, office kitchens, hotel serveries, staff canteens, and similar environments where hot water is required consistently throughout the day but volumes are moderate. For busier operations with significant concurrent demand — such as large catering kitchens or high-footfall food service sites — a higher-capacity model would be worth considering.

If you are weighing up whether this capacity fits your service pattern, or want to talk through the installation requirements for your particular site, the team is glad to help you work it out before you place an order.
