Instanta CTS17F (3001F) 17 Ltr Auto-Fill Counter Top Water Boiler

The Instanta CTS17F is a mains-fed, auto-fill counter top water boiler that connects directly to a cold water supply and heats, maintains, and replenishes water automatically throughout the service day. Unlike manually filled urns, it removes the need for staff to monitor water levels or intervene during busy periods — the unit simply stays ready. Integrated multi-purpose filtration is built into the unit, which is particularly relevant for sites in hard-water areas where limescale accumulation on heating elements is a common cause of early failure and inconsistent output.

In a working service environment — a café running hot drinks across a full shift, a hotel breakfast operation, or a staff canteen — that consistency has a practical value. The LCD fault diagnosis display means that if anything does go wrong, staff can identify the issue quickly rather than waiting for an engineer to investigate. Long-life Incoloy heating elements are a well-proven choice in sustained commercial boiler use, and boil-dry protection provides a safeguard in the event of a supply interruption.

• Mains auto-fill removes manual refilling and reduces the risk of running dry
• Integrated filtration reduces limescale and helps extend element life
• Runs from a standard 13-amp plug — no dedicated electrical circuit required
• LCD fault display supports fast diagnosis and limits service disruption
• Boil-dry protection guards the element if the water supply is interrupted

Installation is practical and straightforward. The unit sits on a counter, requires a cold water feed nearby, and plugs into a standard 13-amp socket. No specialist electrical installation is needed, which keeps setup costs low. It is worth confirming that a suitable water connection point is accessible close to the intended counter position before ordering. A stainless steel drip tray is included to support day-to-day hygiene at the service point.

The CTS17F is well suited to small and medium operations with steady but moderate hot water demand — a café, a hotel servery, a staff dining room, or a similar single beverage station. Sites with higher throughput, longer peak periods, or multiple draw points running simultaneously may find a larger-capacity unit better suited to their needs.

If you would like to talk through whether the output matches your expected service volume, or have questions about positioning and water supply requirements, the team is glad to help you work through it before you order.
