Instanta CTSP11H6 11 Litre Auto-Fill Counter Top Water Boiler

The Instanta CTSP11H6 is a plumbed-in counter top water boiler that connects directly to the cold water mains, refilling automatically to maintain a continuous ready supply of hot water. A built-in filtration system treats incoming water before it reaches the element, and a single non-drip tap dispenses at the set temperature. An LCD display handles temperature adjustment, basic diagnostics, and access to a programmable seven-day timer.

The auto-fill arrangement is what sets this type of unit apart from a manually filled boiler in a working kitchen. There is no level monitoring, no pause to refill, and no gap in hot water availability during service. The integrated filter is a practical inclusion rather than a marketing feature — on hard water sites in particular, limescale accumulation in the element is the most common cause of premature failure and rising descaling costs. The seven-day timer allows the unit to reach working temperature before service begins and power down once it ends, which contributes meaningfully to running costs over the course of a week.

The main operational advantages in daily use:

• Auto-fill keeps hot water available throughout service without manual intervention
• Integrated filtration reduces limescale build-up and protects element longevity
• Adjustable temperature suits a range of beverage types and light food preparation
• Seven-day timer aligns energy use with actual service hours
• Boil-dry and over-boil protection reduce the risk of damage during unsupervised periods

Installation requires a stable counter position with access to a cold water supply and a drain connection for the overflow. The unit runs from a standard 13-amp socket, so no dedicated electrical circuit is needed. It is worth confirming counter depth and the proximity of both the water feed and drainage point before delivery. An optional rear drain outlet offers some flexibility depending on counter layout.

This model is well suited to lower- to mid-volume operations — cafés, small hotel breakfast services, staff canteens, and school kitchens — where counter space is limited and straightforward, reliable operation matters. Sites with consistently high throughput, or where multiple service points need simultaneous supply, would be better served by a larger-capacity unit.

If you are unsure whether this capacity matches your service pattern, or want to talk through the plumbing requirements before committing, the team is happy to work through the details with you.
