That's before any additional work, such as air conditioners, pool pumps etc are done!
Thanks for posting that, good to have a rough idea of what we are paying (way too much) for.
Browse Forums Building A New House Re: Cost of 3 phase power 22Jul 30, 2009 10:32 am I just got quoted $2000 . We're building in Chelsea Heights. Can someone help me bring this cost down? I really don't know anything about these other than we need it for the a/c we want to install. But 2k seems a little too high. So should I be asking my builder for a break down cost?

Re: Cost of 3 phase power 23Jul 30, 2009 11:40 am Hey SPunky, r u sure you need 3phase for your aicond?? How big is your house. I did a search and found your floor plan in a previous post, and i am pretty sure you can get away with a single phased unit. Perhaps the 2K will be better spent on an upgrade you can see and get more use from. Re: Cost of 3 phase power 24Jul 30, 2009 11:54 am you might be able to get by without 3 phase power but the you may have problems with overloading and the safety switch shutting down the power. If you have the air-con a plasma, washer etc etc all going at once it will cause problems. Moved in December 2010 Re: Cost of 3 phase power 25Jul 30, 2009 12:07 pm Well the system we want to put is the ActronAir unit (ESP ULTIMA) and were told that we need a 3 phase unit for something like that, so that if in the case the whole house needs to be cooled, it can be done so. The sales rep from the heating/cooling place said that the cooling part of the system would need up to 20kw of power to be able to do that . I called United Energy and waiting for someone to call me back to let me know if 3 phase is available on our street. I agree that I would rather spend that 2k on something else, lol. I've emailed our construction administrator asking for the break down but she hasn't emailed me back yet. The total size of the house is about 222 sq meter (thats including the garage, which will be 6x6) Mum to 3 kids (including hubby) Building in SE Melbourne. Land settled 17/07/09.

However dont want to confuse your or anything, however in Melb we tend to use heater more often so i usually recommend that people design the house for full heating, preferable GAS as it is cheaper to run. No matter how energy efficient the electric heaters are they always cost more to run ebcause elec is more expensive to buy per kwatt. Then you add on a cooling refridge system like a 15Kwatt which will do more than half of the house. You also need to thick about running cost. Would you be prepared to pay the cost to run the whole house for cooling as it is bloddy expensive. A lot of people i know have top of the range system but are then too scared to run it because of the power build. Re: Cost of 3 phase power 27Jul 30, 2009 12:31 pm I also don't think that we were ever be cooling the whole house at the same time but hubby wanted to have that option just in case . We started off by wanting gas heating and electric cooling (one of those add on systems), which would only cost us about $10k (as apposed to 20k for this unit) but then the sales guy said that you only pay what you use, so because the unit has the ability to go down to 2kW, it would be economical long term. Would that be true? Or is it because we will be using the heater more often than the cooler, we are better off getting a gas heater with an add on and not worry about the 3 phase unit? Oh bugger, I am really confused as to what to do! Mum to 3 kids (including hubby) Building in SE Melbourne. Land settled 17/07/09. Contract signed 01/07/09. Colour Selection 29/07/09. Re: Cost of 3 phase power 28Jul 30, 2009 1:19 pm ah sales people. hmmmm why is it i never agree with them lol. In Vic i would highly recommend gas heating. I am sure others would agree. But dont listen to me check out this web site and put the numbers in your self, and find out what the running cost are. http://www.energyrating.gov.au/ I think you will be blown away........... The pages allow you to place number of hours of usage etc. What i find interesting is that when you compare the actro with the brivis add on cooling the brivis unit it cheaper the run. I would have thought the actrons main advtage admittedly over brivis is the inverter technology, in my eyes it should be much better. Any play around with the heating hours because that where the cost will just fly out of the window. Re: Cost of 3 phase power 29Jul 30, 2009 4:43 pm Thanks for that Borg. Really appreciate your input. I might sit down with hubby and have a look at that website. The thing that worried us with the ad-on cooler was that the heater would ALWAYS be running at min 10kW (say if you get the 10kW unit) and you can't reduce it down to just 1 room. And thats what sold us.... we thought we would be better off paying what we use, rather than having a minimum of 3 points open at any given time if we want the heater running. I was really confused yesterday, thats for sure... but I "think" I am getting a better understanding of it. The way I understood it was that it would take less than 10kW to heat up 3 rooms and therefore we wouldn't be paying more on our bills (as from what the guys said to us was that running a gas heater and electric heater at 10kW wouldn't make a difference.... whereas gas at 20kw vs electric at 20kw would). If we wanted an add-on system (which would be strong enough to cool more than 1/2 of our house), then we would need to put a larger heating syste (say 30kW) and in that case if the heater went on, it would ALWAYS be at 30kW... and thats where the money saver was... if we only use 10kw then thats all that we pay for?! Bleh..... anyways, UE called me back and we DO have 3 power in our street so I guess that's good news and maybe that 2k figure of installing it wouldn't be so. I got an email from AVJ stating that my request has been sent to an estimator ... so will see what they come back in regards to the costing.

Re: Cost of 3 phase power 31Jul 30, 2009 8:43 pm Hi Spunky i think i know how the sales person has confused you. The difference with the two units is although the unit that they have to offer can switch down to lower power, the other cheaper units will simply just turn off after they are done. For example the acron might run at 10kwatts all the time. Where as a 20kwatts will runn at 20kwatts for 30min then turn off for 30min. So on average it would be 10kwatts. This is where the confusion is. Now my above example may have a few assumptions in there. If both units where the same price the acron would be a better unit with better technology. However they are not the same price and you need to ask yourself is it really worth it, when you have to use elec for running the heater. It basically takes away the cost saving. anyway just think about it for a while. Re: Cost of 3 phase power 32Jul 30, 2009 11:21 pm I have since been told that a friend of a friend does 3 phase for house builders and charges $30 a meter including trenches. My house is 230m2 and most air conditioner places recommened a single phase, I actually had to fight to get them to quote on a three phase. Re: Cost of 3 phase power 33Jul 30, 2009 11:29 pm spunkylayla Well the system we want to put is the ActronAir unit (ESP ULTIMA) and were told that we need a 3 phase unit for something like that,) my house is 315m2 and I can get the ESP Ultima SRD175C and that is a single phase 40amp system. I could actually have gone for the next size down (SRD15C) but that is not in Ultima. ’’Quondo Omni Flunkus Mortati ’’ If the women don't find you handsome, they should at least find you handy.

My house is 230m2 and most air conditioner places recommened a single phase, I actually had to fight to get them to quote on a three phase. problably because going to a too big unit is not as energy effecient because the unit will be turning on an off too quickly. ALso you need to have a minimumer of number of ducts open assuming you went for a add on unit off course(without the inverter technology) Re: Cost of 3 phase power 35Nov 04, 2017 6:19 pm Anybody can dig a trench and a conduit and lines but the point is what are the power charges do they charge an extra top of the extra daily line charge and reading the metre I don't know they just want to screw you all the time 1 62023 Would also like an opinion from anyone that has used xcem over hebel for floors.
