Also look at how you can improve insulation and heat loss to house including full anticon under roof panels to get roof space temp down, insulate any west facing walls as a minimum. Look at window glazing or at least good quality drapes and go light colours to outside finishes. Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 3Dec 25, 2019 8:37 pm I'd ditch gas totally. Don't even connect it to your house in this day & age. You'll save money (no daily supply charges for the gas), & help save the environment.
Go an all electric house. As suggested, 6.6kW of solar PV on the roof (make sure your roof is designed well, to accommodate north, or east/west facing panels). RC AC to heat/cool the home. Plus fans to cool (way less energy usage). Evaporative cooling is cheap to run, but only good in very dry climates, not Melbourne. Heat pump or electric element domestic hot water (powered by solar PV). Induction cooktop. Gas bottle for the BBQ. As for your initial questions. Splits are more efficient than ducted (due to energy losses in the ducts). So I'd be looking at splits, maybe multi heads, & maybe a single head or two, whatever fits. I believe single head are usually more efficient?

Since this is a new estate I'm pretty sure I'll end up with sarking & whirleys etc. Unfortunately as I'm on a stricter budget I have to postpone the solar system for a later date.. But I will do it Cheers, Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 5Dec 25, 2019 9:09 pm ddarroch I'd ditch gas totally. Don't even connect it to you house in this day & age.

Hi ddarroch, Thanks for taking time to reply I'm on a strict budget unfortunately, so I will have to postpone the solar system Boutique is really restrictive with regards to the choice of brands when it comes to heating cooling... From what I gather (I'm still waiting for our new home consultant to get back to me on that). Gas heater is Brivis 3* (included) Refrigerated system is also Brivis. So I'm assuming that r/c is Rinnai. I've heard good things about Brivis evaporative systems, but nothing but negative feedback about the Rinnai r/c systems. Would luv to go with a Daikin / LG t/c system if they allow it. Refrigerated system (6* gas + Brivis ICE) is around $15k I know I can get either system done for cheaper post handover... But I'd love to get everything included in the construction loan Cheers, Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 6Dec 25, 2019 9:10 pm Lucky88X With Boutique I'm getting double glazed windows as standard. Since this is a new estate I'm pretty sure I'll end up with sarking & whirleys etc. Check with the "Sarking" and ask if it is Anticon style insulation which is a fibre glass batt bonded to foil type sarking or just sarking alone. You are half way there with the double glazing but ask about the other stuff as well as it is about a total package. Lets just hope one day the penny will drop with W.A Builders and they start building more efficient homes rather than the totally inefficient double brick heat soak houses we currently have now. Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 7Dec 27, 2019 4:53 pm lucky88x I am installing a Fujitsu ducted air-con to my 3 bedroom house in Melbourne, total cost is ~13K. It is a 15.8kW and would allow 2 zones with 8 outlets. The quote I receive was from early Dec 2019. I searched and found a similar package in Sydney before with much lower price for a slightly smaller system, also Fujitsu. Hope it helps.

Hi ir0nbark1, Thanks for taking the time to reply Is this a ducted reverse cycle system? I'm a bit lost with all this different names used, I feel as if ducted reverse cycle = refrigerated systems. Did you ask about these from your installer? Cheers, Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 9Dec 27, 2019 5:44 pm Yes reverse cycle is a refrigerated system being that it can be reversed so it has the ability to heat and cool. It is pretty much what everyone installs these days as it is reasonably efficient. Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 10Dec 27, 2019 5:50 pm Brett0004 Yes reverse cycle is a refrigerated system being that it can be reversed so it has the ability to heat and cool. It is pretty much what everyone installs these days as it is reasonably efficient. Hi Brett, Yeah, but according to Boutique documentation, if I go ahead with the refrigerated system, they'll upgrade the gas heater to a 6* unit and then add a cooling unit to use the same ducting. As far as I can see, they're selling the below system : Brivis Starpro 6* + Brivis ICE (add on cooling) If I'm forking out anything above $10k, I don't want a Frankenstein system I'm going to wait for the consultant to get back to me with all the options.

Seems that a lot of people are ditching gas altogether.

If I'm stuck with the Brivis refrigerated system, I'll be going ahead with an evaporative cooler with a 6* gas heater. Unfortunately wifey wants a gas cook top Cheers, Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 13Dec 27, 2019 6:13 pm Lucky88X Unfortunately wifey wants a gas cook top Cheers, Until she sees an induction cooktop in use, boil water in 30 seconds and infinite temperature control. Ever seen a pot cooking with a sheet of paper towel between the pot and the cooktop. then cold to touch in seconds. Amazing!!! Watch this then take her for a demonstration, https://www.youtube.com/watch?v=fwwhtsdbKFc Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 14Dec 28, 2019 12:10 am [quote="Lucky88X":f1dmhs7j] Unfortunately wifey wants a gas cook top Cheers,[/quote:f1dmhs7j] Has she ever used a good quality induction cooktop? It's far more efficient than gas, gets up to temperature extremely quickly, is easy to control the temperature, & far easier to clean up spills. Lots of people are moving to induction, & love it (plenty who have come from gas). Some people still prefer gas, but from what I've read I wouldn't say they're the majority. Energy use for cooking is not particularly large. It's much larger for space heating/cooling & heating domestic water. So it's not the price of gas usage (for cooking) that will kill you. It's the cost of the daily connection free, which really adds up! If your wife hasn't experience induction cooking, I'd try & convince her. Read up on reviews (there's positive reviews everywhere), or maybe try it out somewhere. With induction you'll save money, & improve your home's air quality (over gas). Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 15Dec 29, 2019 12:43 pm Hey lucky88x Brivis provides gas heating mainly and the option you mentioned is an addon for cooling using the same ducted system. The quote I gave was for all electric air-con. In general there are a few options 1. As you have, gas heating and either evaporated cooling (low power usage) or refridgerated cooling as addon. 2. Fully electric air conditioning as information I provided. Some give zone control and multiple outlet throughout the house with either round vents or square with adjustable angles. 3. Multi head aircon system which means each room will have an indoor unit for both heating and cooling, same as normal aircon, and only one big outdoor unit. This will give advantages as to control temperature for each room but you will need to consider hallway and other areas in the house as well. Hope it helps.

Cheers, Hey - I think the only way is after the house is built fully and then landscaping & fence & driveway is completed, then I have to call "Solaray" and start the process? This is what I have been told here and there by some. Happy to be corrected if there is a quicker/cheaper/better way and if the actual house builder [eg: M , B , PD] can take care of it during the build phase Tesla Tom ('Ludicrous Feed') [click here for YouTube link] and Adam ('Tesla Straya') [click here for YouTube link] used 'Solaray' for their roof solar panel install, and here is the Solaray youtube click link By the way, which estate are you building in (Platform, Kinbrook, Donnybrae, Peppercornhill, Olivine)? Is there an issue with the Donnybrook area having rocks underneath and an extra AUD$15,000 - $20,000 has to be spent on top of the titled land purchase cost? Read about the rock issue on this forum (click here for direct post link) Re: Electricty & gas -- for my build some involved in the purchase are insisting that gas cooking is a must, but I personally am of the view that 'electric cooking' is sufficient with an electric water heating system that will be powered off the solar panels & the grid if/as required, and installing gas will be extra costs and also cost more money with maintenance over the next 10-15 years compared to electric cookstop & water heating. Would also like to hear your recommendation for a conveyencer lawyer (whose law practice has a trust account) that you perhaps used for your Donnybrook land purchase / section 32 paperwork transaction. Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 19Jan 01, 2020 11:31 am Well, we are waiting for the stage 10/11 land release at Olivine. We've visited Donnybrae & Kinbrook. Kinbrook - everything was good until I discovered that the only network option would be Opticom fiber - which is a huge deal breaker. Not to mention the potential noice restrictions etc. Due to the railway line & the increase in cost. Donnybrae - All good except for the high price & the fact that they're piggybacking on the infrastructure given by Olivine, Merrifield & Cloverton. So I just couldn't stop feeling as if I'm getting ripped off lolz. Platform - Apparently there's some sort of a litigation issue going on. Nothing that I know for sure but smoke is almost always followed by fire. So don't want to take a chance. Re: New Build - Ducted Refrigerated OR R/c Multi Splits OR R 20Jan 01, 2020 11:36 am AFAIK Donnybrook & the surrounding area is on volcanic rock or whatever the geologists call it So rocks are to be expected, it depends on your luck whether you'll end up with a block that has a friggin huge boulder underneath or not. Boutique mentioned that the biggest they've charged in around Donnybrook was $20k (fixed site costs). So when I'm doing finances I'm planning for an additional $22k Hopefully it won't be that much Hi all, sorting out the ducted air con for a 350sqm double story house.
