Frequently asked questions

The 6.3kW unit is ideal for point-of-use and lower demand applications, such as a single bathroom, basin, or kitchen sink.

It can supply more than one outlet, but performance will depend on demand. For simultaneous multi-outlet use, a higher capacity unit may be more suitable.

The unit delivers water up to a maximum of 45°C, in accordance with AS3498.

No. The 6.3kW model has a fixed maximum outlet temperature and is not adjustable.

No. With a maximum outlet temperature of 45°C, a tempering valve is not required (AS3498 compliant).

The unit activates at a minimum flow rate of 2L/min. Below this, the heater will not operate.

Yes. Output temperature can vary depending on inlet water temperature and flow rate, particularly in higher demand situations.

No. As an electric instantaneous system, it does not require flues, ventilation, or gas connections.

No. The unit is not designed to provide heated potable (drinking) water.

Minimal maintenance is required. Regular inspection and descaling (in hard water areas) is recommended to maintain performance.

6.3kW → best for single outlet or low-demand use. 8.5kW → better for multiple outlets or higher demand.
