Types of commercial kettle
Commercial kettles in HC's range cover bench-top and wall-mount water boilers (urns), instant boiling water units, and high-capacity tea-service boilers. Suppliers include Birko, Roband, Stoddart, and Burco. Choose by service style and volume — auto-fill plumbed units suit cafés running continuous tea and coffee service; manual-fill units suit smaller venues without dedicated plumbing; instant boiling units suit high-throughput situations where waiting for re-boil is unacceptable.
- Auto-fill water boilers: plumbed-in 20–40 L capacity units with thermostat control — the café and small-restaurant standard.
- Manual-fill water boilers: 8–20 L capacity for venues without plumbed water service; require regular top-up during service.
- Instant boiling water units: on-demand boiling water dispensers for high-throughput tea and instant-coffee service.
- Tea-service urns: dedicated event-and-function kettles with insulated tank and drip-tray for buffet tea service.
- Bench-top traditional kettles: for low-volume venues and back-of-house staff areas where commercial throughput isn't needed.
Sizing and operation
Allow 50–100 cups per litre of capacity per service for mixed tea and coffee venues. A 20 L auto-fill boiler suits cafés serving 200–400 hot drinks per service; 30 L handles 400–600; 40 L handles full restaurant lunch and dinner service. For event hire, 8 L manual-fill urns suit functions of 50–80 guests; larger 30 L+ units cover 200+ guest events. Confirm power requirements: most boilers run on 240 V 10 A, but high-capacity instant boiling units may need 15 A or 3-phase supply for fast recovery between draws.
Operating considerations
- Plumbing: auto-fill units need cold-water supply with isolation valve; budget 1.5 m of accessible 15 mm copper or PEX line within 3 m of the unit.
- Filtration: inline carbon filter on the supply line dramatically reduces calcium scale on heating elements and extends service life.
- Energy efficiency: look for double-walled insulation and standby modes to reduce overnight energy use.
- Drainage: auto-fill units have an overflow drain that needs plumbed connection; manual-fill units don't.
- Safety features: look for child-lock taps, overheat cut-off, and dry-boil protection in any unit going on a busy public-facing counter.
Working with our team
Hospitality Connect's catalogue depth in this category reflects 21+ years of supplying Australian commercial venues — single-supplier convenience across appliances, smallware, and consumables means fewer purchase orders, consolidated freight, and consistent specification advice from a team that's seen most operational scenarios before.
Specification matters more than buyers expect — undersized or oversized purchases waste both capital and operating cost. Our trade team spec'd thousands of fitouts across cafés, restaurants, hotels, function venues, and contract kitchens, and we'll match recommendations to your venue brief rather than push the catalogue.
