Beverage Air 5‑Litre Water Cooler vs Noritz NRCB Combi Boiler

The Beverage Air 5‑Litre Water Cooler is a countertop appliance designed for homes and small offices. It holds up to 5 L of bottled water and provides hot, cold, or ambient dispensing at the push of a button. The unit features a built‑in stainless‑steel cooling coil and a rapid‑heat element, delivering chilled water in under 30 seconds and boiling water in about 2 minutes. Its sleek white finish and low profile fit easily on kitchen counters or office desks, while the removable drip tray and easy‑fill reservoir simplify maintenance. The cooler operates on standard 120 V AC power and includes child‑lock safety for hot water dispensing.

The NRCB series is Noritz's combination boiler, which handles both space heating and domestic hot water from a single wall-mounted appliance. That combination is the point: instead of a boiler for the radiators and a separate tank water heater, one unit does both, freeing the floor space a tank would occupy and removing the standby heat loss that comes with keeping a tank hot around the clock. Because it is tankless on the hot water side, supply is continuous rather than limited by tank capacity, so back-to-back showers do not run out. Noritz is a tankless water heating specialist with residential and commercial ranges, and supports the NRCB with a sizing guide, plumbing diagrams, BIM and Revit files, installer training, a PROCard programme and installer and servicer locators.
