Instanta CTS11F 11 Litre Auto-Fill Counter Top Water Boiler
£543.00(£651.60 inc VAT)
Delivery Information
Price Match
The Instanta CTS11F is a mains-fed, auto-fill counter top water boiler designed to provide a continuous supply of hot water throughout the service day. It connects directly to a cold mains supply, maintains water at a consistent serving temperature, and refills automatically — removing the need to monitor levels or wait for a manually filled vessel to recover. Filtration is built into the unit itself, treating incoming water before it reaches the tank rather than relying on a separate accessory.
In practice, this type of boiler suits operations where hot water demand is steady and consistent rather than extremely high-volume. A staffed café, hotel breakfast servery, workplace canteen, or school kitchen will generally find it keeps pace comfortably across a full service. The auto-fill function means the unit stays ready without staff intervention, and the LCD fault diagnosis display helps identify any issues promptly — reducing the likelihood of unnecessary engineer call-outs.
From a day-to-day operational standpoint, several practical advantages are worth noting:
- Auto-fill operation keeps the unit ready throughout service without manual intervention
- Integrated filtration reduces scale build-up and helps protect element life
- Incoloy heating elements provide proven longevity under regular commercial use
- Boil-dry protection guards the unit if the water supply is interrupted
- LCD fault display reduces diagnostic time and unnecessary engineer visits
Installation is notably straightforward. The unit runs from a standard 13-amp plug, so there is no requirement for a dedicated electrical circuit or additional wiring work — a genuine advantage on sites where electrical capacity is limited or a quick setup is needed. A nearby mains cold water connection is required for the auto-fill function to operate. It is worth confirming the worktop can support the unit at full capacity, and allowing adequate clearance for ventilation and routine access.
This boiler is well suited to small and medium operations that need dependable hot water without the complexity or footprint of a larger commercial unit. It is commonly used in cafés, care homes, hotel serveries, school kitchens, and workplace catering facilities. For sites handling significantly higher volumes or requiring simultaneous draw from multiple points, a higher-capacity unit may be worth considering.

Frequently asked questions
Is this boiler suitable for a busy café or will it struggle to keep up?
The CTS11F is well matched to operations with steady, moderate hot water demand — a staffed café, small canteen, or hotel servery will typically find it keeps pace without difficulty. If your service involves very high simultaneous demand or multiple draw points at once, it is worth discussing whether a higher-capacity model would be a better fit for your volume.
What does installation involve — do I need an electrician or a plumber?
The unit runs from a standard 13-amp plug socket, so no electrical installation work is needed. You will need a mains cold water connection nearby for the auto-fill function to operate, which may require a plumber to fit a suitable supply point if one is not already in place. Beyond that, installation is straightforward and can usually be completed quickly.
How does the integrated filtration work and does it need servicing?
The filtration system treats incoming mains water before it enters the tank, helping to reduce limescale build-up on the heating elements and internal components. Like any filtration system, the filter will require periodic replacement — the interval will depend on local water hardness and usage levels. Keeping on top of filter changes is one of the most effective ways to protect element life and maintain consistent performance over time.
