Instanta WMS2 2.5 Ltr Wall Mounted Auto-Fill Water Boiler

The Instanta WMS2 is a compact, mains-fed water boiler designed to mount directly to the wall, keeping the worksurface clear while maintaining a ready supply of hot water. At 2.5 litres, it draws continuously from the cold mains supply and refills automatically, so there is no manual topping up required during service.

In practice, this unit performs reliably in settings where hot water demand is steady rather than intense — a back-office tea point, a staffroom, a waiting area, or a satellite beverage station within a larger operation. The auto-fill mechanism means staff do not need to manage the unit during service, and because it maintains a heated reservoir throughout the day, hot water is available on demand without delay.

The wall-mounted format brings several practical advantages worth noting:

• Frees the worksurface entirely for preparation or service use
• Non-drip tap reduces spillage and keeps the area beneath clean
• Stainless steel casing wipes down quickly and stands up to daily use
• Mains auto-fill removes any manual water management during service
• Fixed wall position keeps the unit stable and out of the flow of work

Installation requires a cold mains water connection routed to the mounting position and a suitable power supply — a hardwired connection is recommended for any permanent installation rather than relying on a standard socket. Wall fixings must be appropriate for the unit's loaded weight, and it is worth confirming adequate clearance beneath the tap for the cups or jugs in use. Routine descaling is a standard maintenance requirement, so access to the inlet and internal components should be factored into where the unit is positioned — particularly in hard water areas.

This model is well suited to low-to-moderate demand environments: small cafés, office kitchens, healthcare waiting areas, or supplementary hot water points on larger sites. Where a site needs to support continuous high-volume drink service through a busy period, a higher-capacity unit would be a more dependable choice.

If you are unsure whether this capacity matches your expected demand, or you want to talk through the installation before ordering, the team is glad to help you work it out.
