Bosch 16P

The Bosch 16P delivers 16 litres of hot water per minute, making it suitable for small to medium-sized household, typically 2-3 people with up to two bathrooms. It handles simultaneous demand from one shower and a basin tap running at the same time, which covers the morning routine in most two-bathroom homes. It uses a standing pilot light ignition system and operates entirely without electricity, making it a practical choice for outdoor installations and properties with limited electrical access near the hot water location.

The 16P and 16H have the same 16L/min flow rate and the same physical footprint (936mm H x 460mm W), but differ in ignition. The 16P uses a standing pilot light, a small continuously burning gas flame, while the 16H uses HydroPower ignition, which harvests energy from water flow to start the burner with no pilot flame, no electricity, and no batteries. The 16P is available in natural gas only. The 16H is available in both natural gas and LPG. If you are on reticulated natural gas and want the simplest, lowest-maintenance option, the 16P is a well-proven choice.

No. The Bosch 16P relies entirely on its standing pilot light for ignition and requires no electrical connection. This is a meaningful practical advantage for installations in older Perth homes or on the side of a house where a power point is not nearby. Some competing continuous flow units require a 240V power point, which can add cost and complexity if one needs to be installed. The Bosch 16P eliminates that requirement entirely.

The Bosch 16P is backed by a 2-year parts and labour warranty for domestic installations, plus a 10-year warranty on the heat exchanger. The heat exchanger is the main copper component that transfers heat from the burner to the water, and is the most expensive part to replace. The 10-year warranty reflects Bosch’s confidence in its durability. To maintain warranty validity, the system must be installed by a licensed plumber and gas fitter in line with Bosch’s instructions. Ember issues a Certificate of Compliance with every installation, confirming this requirement is met.

At 16L/min, the Bosch 16P can handle one standard shower (typically 7-9L/min) plus another hot water outlet simultaneously without significant performance drop. Running two showers at full flow at the same time will push the unit to near its maximum capacity, which can result in a slight temperature reduction in both outlets. For households where two showers are frequently used simultaneously, such as a family with teenagers or a home with two ensuites, we would recommend the Bosch 16H or stepping up to a Rheem 20 or 26 for greater headroom.

The price includes the Bosch 16P unit, all standard installation labour, connection to existing gas and water lines, and free removal and disposal of your old hot water system. The price is for a like-for-like replacement where the existing installation is accessible and in a standard configuration. If gas line modifications, additional valve work, or non-standard pipework is needed, the Ember technician will confirm any variation to the price before starting. All prices are GST inclusive. There is no call-out fee.
