FAQ

1. Can I install the DHF C-AU water heater in new applications/buildings?

The DHF hot water system is hydraulically controlled and as such you may have fluctuation issues if installed in conjunction with water saving tapware and shower roses.

We recommend the use of an electronically controlled system such as the DHE AU, DHB-E AU or DEL AU 3 phase instantaneous water heaters for new applications and buildings.

2. I have an old 3 phase instantaneous hot water system, what size unit will I require to replace this with a DHF?

Your electrician can advise what size the fuses are for your existing hot water unit, this will confirm the appropriate replacement model.  The DHF C-AU 13 is 19.7 Amps per phase and the DHF C-AU 15 is 22.5 Amps per phase.

3. Are spare parts available for the DHF instant hot water system?

Yes, our spare parts division can assist with parts for the DHF C-AU. Our service and spare parts division can be contacted on 1800 153 351.
