Re: Install heating/cooling during build or wait and see? 10Jul 24, 2016 12:24 am ddarroch As for AC, you said "ducted reverse cycle split system". I'm no expert, but I don't think you can have a ducted split system, I think it's either "ducted" or "split". Sorry to correct you there but a ducted system is still be a split system if the compressor and outdoor coil is separate to the indoor unit in the ceiling and connected by pipework as opposed to a package unit with everything in the one enclosure/housing. Refer to here https://en.wikipedia.org/wiki/Air_conditioning#Split_systems hope that clears it up Re: Install heating/cooling during build or wait and see? 11Jul 24, 2016 8:26 am Good question justalittlebithippy and great response ddarroch. Just to add from our experience we have a total electric house with induction cooking, heat pump hot water and 5kv PV, no heating or cooling but have prewired for 2 splits. Have been in the house for one summer and nearly one winter and could count on one hand the times it may have been nice to take the chill off but instead put on a jumper. We use fans, high louvre windows and control cross ventilation. Definitely agree that window furnishings help and probably why we have experienced the coolness occasionally as we didn’t want covering on our rear windows cause of not needing privacy, will look into this before next winter. We're in northern nsw for prospective. Good luck!

Refer to here https://en.wikipedia.org/wiki/Air_conditioning#Split_systems hope that clears it up Thanks for the correction Bels, good to know. You're certainly the expert Come to think of it, the system in my parent's apartment is a ducted split I'm guessing they're often a good option, with the seamless look of a ducted system, but with lower losses due to shorter duct runs? Re: Install heating/cooling during build or wait and see? 13Jul 26, 2016 1:26 pm Thanks everyone I certainly have thought about doing the no gas connection electric only house, and I think that's probably what I will do for my forever house, but I'm just not sure I can justify the extra upfront expense for this house. Unless it would be the same cost and I've just missed something? And yes, will probably be doing a combination of heavy curtains and the honeycomb blinds, and definitely pelmets. The honeycomb blinds do look very interesting, can anyone recommend a good supplier please? The other thing is I'd really love a coonara type wood heater in the main living area because I love the feel of real fire, would I be crazy to just put that in earlier than I was originally planning and see if that negates the need for ducted heating? And one last question, does anyone have any experience with whole house fans vs individual ceiling fans in each room? Cheers Re: Install heating/cooling during build or wait and see? 14Jul 26, 2016 6:04 pm Hi I think that your insulation is pretty low, 1.5 in the ceiling and 2.5 walls is hardly anything. The roof is where you will lose most. Think about putting a lot more up there. Cheers Lorri Re: Install heating/cooling during build or wait and see? 15Jul 26, 2016 8:12 pm That's 5.1 in the ceiling Lorri that was what the gov yourhome website suggested for my area, but happy to hear arguments for more.

Hey mate, are you comparing a ducted refrigerated system to a ducted gas heating system with possibly addon cooling? You are right to a degree with the duct losses but it's not really an apples to apples comparison. Re: Install heating/cooling during build or wait and see? 17Jul 26, 2016 10:03 pm Hi Justalittlebithippy It might pay to consult a green engineer who can look over your plans and would make recommendations on what you could improve on if you were aiming for a passive house.

I thought 1.5 was pretty low LoL Re: Install heating/cooling during build or wait and see? 19Aug 03, 2016 2:43 pm Lorri Lorri Hi I think that your insulation is pretty low, 1.5 in the ceiling and 2.5 walls is hardly anything.
