Instanta CTSV135T18 (MOD18) 135 Ltr Twin Tap Counter Water Boiler

The Instanta CTSV135T18, also referred to as the MOD18, is a 135-litre autofill counter-mounted water boiler fitted with twin dispensing taps. It is designed to provide a continuous supply of hot water for high-demand commercial environments — from hotel banqueting and contract catering through to busy staff restaurants and large canteens. The autofill function means the unit replenishes itself from the mains water supply without operator intervention, maintaining a ready reservoir throughout service.

At 135 litres, this is a substantial unit built to handle sustained throughput during extended service periods. The twin-tap configuration allows two members of staff to draw simultaneously, which meaningfully reduces bottlenecks during peak times such as morning coffee service or a large seated lunch. Recovery performance is a practical consideration at this capacity, and the three-phase hardwired supply this unit requires is what makes consistent, efficient heating at scale possible — something a single-phase unit of comparable size would struggle to match.

From an operational standpoint, the key practical advantages include:

• Twin taps with swivel arms reduce spillage and keep the service area cleaner
• Autofill operation removes the need for manual monitoring or refilling
• Low voltage switching adds a layer of operational safety in wet environments
• Onboard diagnostics help maintenance staff identify issues quickly, reducing downtime
• Counter-mounted footprint keeps it accessible without consuming floor space

Installation requires a three-phase hardwired electrical connection, which must be carried out by a qualified electrician. A mains cold water supply connection is also needed for the autofill function. The unit is counter-top mounted, but at 135 litres full it carries considerable weight — the supporting surface and any cabinetry beneath should be assessed for load-bearing capacity before installation. Access for routine servicing and descaling should also be factored into where the unit is positioned.

This model is well suited to operations that need a reliable, high-capacity hot water supply running throughout a full service day — hotel F&B operations, large staff canteens, contract catering kitchens, and similar high-footfall environments. For smaller operations or sites without three-phase power, lower-capacity single-phase models are available. For very high-volume sites where demand consistently outpaces a 135-litre reservoir, a higher-output boiler may be worth considering.

If you are unsure whether this capacity and configuration is right for your operation, or if you have questions about the installation requirements for your site, our team is happy to talk it through before you commit.
