Instanta CTS10 10 Litre Counter Top Water Boiler Mains Fed

The Instanta CTS10 is a mains-fed, auto-fill counter top water boiler with a 10-litre capacity. Rather than relying on manual filling, it connects directly to a cold water supply and replenishes continuously, keeping the unit ready throughout service without requiring staff attention. Hot water is dispensed through a single tap, which keeps operation simple whether the unit is positioned front-of-house or in a back-of-house prep area.

In practice, this size of boiler suits operations with a steady, moderate demand — a café during a mid-morning rush, a workplace canteen across a lunch sitting, or a hospitality team servicing meeting rooms through the day. The continuous auto-fill means recovery is ongoing rather than in batches, which helps maintain consistent output during periods of sustained use. The Incoloy heating element is a well-established choice in commercial water boilers, offering better resistance to scale than standard elements — a meaningful consideration in hard water areas where element longevity is often a maintenance concern.

From a day-to-day operational standpoint, the key advantages are:

• Auto-fill removes the need for staff to monitor or top up the unit during service
• Single-tap dispensing is straightforward and clean under consistent demand
• Incoloy element performs reliably in hard water areas and typically lasts longer before replacement
• Built-in self-diagnostics flag faults early, helping to avoid unplanned downtime
• Removable stainless steel drip tray makes end-of-day cleaning quick and easy

Installation is uncomplicated for most sites. The unit runs from a standard 13 amp plug and is supplied with cable, so no dedicated electrical circuit is required. You will need a mains cold water connection nearby — the CTS10 is not suited to locations without a plumbed supply. It is worth confirming available counter space and access to a suitable waste point for the drip tray before finalising the position.

The CTS10 is well suited to cafés, smaller hotel beverage stations, workplace kitchens, and catering prep areas where a reliable plumbed hot water supply is needed without the footprint of a larger undercounter or wall-mounted unit. For very high-volume operations — a busy hotel breakfast service or a large restaurant kitchen with continuous heavy demand — a higher-capacity model is likely to be a better fit.

If you would like to talk through whether the CTS10 matches your service volumes or have questions about the plumbing requirements for your site, the team is happy to work through it with you before you go ahead.
