I bought an apartment in Maroubra and moved into it a couple of months ago, but have noticed the hot water only lasts around 15-20 minutes, due to the current single phase electric system being just a 50L tank in my kitchen cupboard. I therefore need to work out whether to get three phase electricity set up in my apartment and replace the 50L tank with a decent instant electric model... or alternatively have a plumber install a 125L tank in the laundry and configure the plumbing from there instead. Strata suggested that wouldn't have any problem with approving three phase if I want to get it installed and I can see four wires connected to the building from the street pole - so does anyone know who would be a good person to contact regarding setting up three phase to the apartment? Any rough idea what it would cost to do this as well? I guess I should get a quote on installing three phase and a quote on replumbing from the laundry before deciding how to proceed - but no idea where to start with getting a quote on three phase - can any electrician do this? Any advice would be appreciated!
