The Instanta WMS10 is a mains-fed, wall-mounted water boiler with a 10-litre capacity. It connects directly to the cold water supply and refills automatically, maintaining a consistent supply of boiling water throughout the day without any manual filling or intervention from staff.

In steady-demand environments — a café, tearoom, hotel breakfast service, or staff canteen — this type of unit earns its place quickly. Hot water is available reliably across the full service period, and because the auto-fill mechanism manages water levels without staff involvement, there is no interruption to service when the boiler empties. The wall-mounted position keeps worktop and floor space clear, which is a genuine advantage in compact servery areas where every surface tends to be occupied.

From an operational standpoint, the practical advantages are straightforward:

Auto-fill removes manual water management during service
Wall-mounted design frees up worktop and floor space
Non-drip tap reduces spillage and helps keep the servery tidy
Stainless steel construction is robust and easy to clean
Compact form suits smaller kitchens, servery counters, and back-of-house areas

Installation requires a mains cold water connection and an appropriate electrical supply. The WMS10 is typically hardwired rather than plug-in, so if a fused spur is not already in position, an electrician will need to be involved before the unit can be commissioned. Wall fixing should account for the weight of the unit when full, and it is worth confirming the mounting position allows clear access to the tap and any service points before installation is finalised.

The WMS10 is well suited to small-to-medium operations with moderate, consistent hot water demand throughout the day. It is not designed for high-volume draw-off or sites needing simultaneous multiple dispensing points — for those applications, a larger-capacity unit would be a more appropriate choice. At the other end, very low-volume sites may find a smaller model offers a more economical fit.

If you are unsure whether this capacity suits your service pattern or want to talk through the installation requirements, the team is happy to help you work it out before you commit.

Frequently asked questions

Is a 10-litre capacity sufficient for a busy café or hotel breakfast service?

For moderate, continuous demand — such as a café serving teas and coffees steadily across the day, or a hotel breakfast service with a manageable number of covers — a 10-litre auto-fill boiler is generally adequate because it refills and reheats continuously rather than relying on a fixed batch. Where demand spikes sharply or multiple staff need to draw hot water simultaneously, a higher-capacity model is likely to be a better fit.

Does the WMS10 need a plumber and an electrician to install?

Yes, both are typically required. The unit connects directly to the mains cold water supply, so a plumber will need to run a feed to the mounting position. On the electrical side, the WMS10 is usually hardwired to a fused spur rather than plugged into a standard socket, so if a suitable spur is not already in place, an electrician will need to install one before the boiler can be commissioned.

Can the WMS10 be mounted anywhere on the wall, or are there positioning requirements?

The unit needs to be positioned where a mains water feed and an appropriate electrical supply can be routed without excessive disruption, and the wall fixing must be capable of supporting the weight of the boiler when full. It is also worth ensuring the tap is at a comfortable working height and that there is clear access around the unit for daily use and any routine servicing.
