Instanta WMS5 (WA5N) 5 Litre Wall Mounted Water Boiler

The Instanta WMS5 is a compact, auto-fill wall-mounted water boiler with a 5-litre capacity, designed for continuous hot water provision in commercial environments. It draws water automatically from a mains connection, maintains a constant temperature, and delivers hot water on demand through a single dispensing tap — making it a practical choice wherever a reliable, space-efficient solution is needed.

In service environments where staff are consistently preparing hot drinks, instant noodles, soups, or similar, a unit like this removes the need for a separate kettle or countertop boiler. The auto-fill function means the tank replenishes without manual intervention, which keeps disruption to a minimum during busy periods. At 5 litres, the capacity suits smaller service points rather than high-volume operations; it performs reliably where demand is steady rather than intensive.

Practical advantages for day-to-day operation include:

• Wall-mounted installation frees up valuable worktop and counter space
• Auto-fill eliminates manual refilling and reduces staff interruption
• Single non-drip tap gives clean, controlled dispensing with minimal spillage
• Stainless steel construction is straightforward to wipe down and keep hygienic
• Constant-temperature holding means water is ready without a wait between draws

Installation requires a mains cold water connection and an appropriate power supply — whilst the unit can run from a 13-amp socket, a hardwired connection is generally recommended in commercial settings for reliability and compliance. It should be positioned at a practical dispensing height and within reach of both the water supply and the electrical connection. Wall fixings need to be suitable for the weight of the filled unit, so checking wall construction before installation is worthwhile.

The WMS5 is well suited to smaller cafés, office kitchens, staff canteens, hotel serveries, and similar environments where hot water is needed consistently but volumes are moderate. For higher-output sites — such as busy restaurant kitchens or large catering operations with significant concurrent demand — a larger-capacity model would be worth considering.

If you are unsure whether this capacity fits your service pattern, or have questions about installation requirements for your site, the team is happy to talk it through before you commit to an order.
