Instanta CTSP11H6 11 Litre Auto-Fill Counter Top Water Boiler

The Instanta CTSP11H6 is a plumbed-in, auto-fill counter top water boiler with an 11-litre capacity and an integrated filtration system built into the unit. It connects directly to a cold water supply, refilling automatically to maintain a consistent volume of hot water on demand. A single non-drip tap dispenses water at the set temperature, and the LCD display provides basic diagnostics alongside controls for temperature adjustment and the programmable timer.

In a busy service environment — a hotel breakfast operation, a staff canteen, a café with steady hot drink throughput — this kind of unit earns its place by being consistently ready. Auto-fill means there is no manual refilling between services, and the integrated filter reduces limescale accumulation in the element and tank, which matters particularly on sites with hard mains water. The seven-day timer means the boiler reaches working temperature before the first service without being left running overnight unnecessarily.

From an operational standpoint, the practical advantages are straightforward:

• Auto-fill removes the need for manual intervention during service
• Integrated filtration protects the element and reduces descaling frequency
• Adjustable temperature suits both beverage service and light food preparation use
• Programmable timer helps manage energy use around service hours
• Over-boil and boil-dry protection reduce the risk of damage during unsupervised periods

Installation is straightforward for a plumber: the unit sits on a stable worktop and connects to the cold water mains via the supplied hose. A drain connection is required for the overflow, with an optional rear drain outlet to suit different counter layouts. The unit runs from a standard 13-amp socket, so no dedicated electrical supply is needed. It is worth confirming available counter depth and proximity to both a water supply and drainage point before ordering.

This model is well suited to lower- to mid-volume sites — cafés, small hotel operations, staff kitchens, school canteens — where a compact footprint and simple operation are priorities. Sites with significantly higher throughput, or where multiple service points need supplying simultaneously, may find a larger-capacity or higher-output model more appropriate.

If you are unsure whether this capacity suits your service volumes, or have questions about plumbing the unit into your existing setup, the team is happy to talk it through before you commit.
