Luke, I think Aussies are starting to put it into bathroom renovations now. My Sydney DD added it to hers - with 4 young children it was worth it, especially overnight, and it made a huge difference - but for just myself I find the combination ceiling fan/heater is sufficient for shower time. I believe there is not a lot of difference in cost between gas and electricity here, but the connection costs can be considerable, if it is even available, otherwise bottled gas is very expensive. For myself generally, it is extra clothes during the day and a small electric fan heater at night while watching TV with a cosy throw for any really cold nights.

@solarventi, Hi, sorry, I didnt work it correctly, It is an interesting concept, but I am not getting it>>> bit slow... How do you heat up in winter in Vic when we get very little sun and the weather has turned Artic this year, Main reason I am noticing the cold, especially when working outside. I do have low blood pressure so feel the cold, but the red clothing next to skin works a charm. I would like to understand... I have seen on uTube where they DIY passive heat I liked the pictures but no explanation and these were using exisiting windows .. I this with gap at bottom on outside so cold air comes in and gap at top on inside so warm air into house.... but got to technical for me. And I get confused, as hot air rises and I dont understand why fans are at the top in newer models not at bottom [of heaters] But I would mind understanding how it works.. Am going to check the website, TU very much. I have bats to put in kitchen reno but would like something to attach to the corrogated iron so there is no gap between iron and bats. Appreciate your help and will check again on your site to see if I missed anything :)

my suggestion would be to keep the new kitchen in proportion to the size and scale of the whole house so i prefer option 2 with cabinets only as high as the top of the window, tall narrow fridge (less than 80cm wide) next to the back door with wall mounted mw and wall cabinets all round, no tall cabinets, more counter on the fridge wall then stove, sink and dw along the window wall to make sure that there is counter on either side of the stove and sink and locations for a toaster, kettle and other appliances..but exact location of appliances depends on budget and sizes of all the cabinets you want to use.. but, if you plan to remove gas in future, why not start with electric appliances and best insulation ready to add solar power at a future date? ...eg check out the electric air sourced hot water heaters and consider an electric flame heater for the kitchen fireplace and save the gas heater for the hew rear living area although it may be possible to have one heater with hot air connected to the other rooms with an in roof ducting system and, if you have long term plans to alter the rear lean-to research options for renovating the whole house and then plan all the work in stages...eg i would have the new laundry/bathroom next to the refurbished bedroom (master suite?) and have the future new rear living area with the north aspect

Daryl, I for one, have been following this thread with great interest since your comment and am very sorry to hear the problems you have had. I had never heard of any of this, but with the dramatically increasing incidences of asthma, mental illness and depression, attention deficit and behavioural problems with children especially, autism - the list goes on - I often stop to wonder why, I know when I was young half of these issues didn't seemed to exist, yet did they and and no one knew about them, or is this because there are more people in the world now or is it all a part of modern living and why? Pollution has been blamed for many things but it seems as fast as we clean up one form of pollution we start another such as this. Technology is advancing at a crazy pace and the younger generation are eager for more and more but is anyone really stopping to investigate health issues or are we just becoming obsessed not just with the profits to be had from it, but also to free ourselves from everyday drudgery and live a Jetsons life style. We all want more free time, but what are we doing with it? In many cases working longer hours to pay for it !! It seems we are too obsessed with "improving" our lives to stop and question any consequences. For we seniors, this is not doing us any favours, we were not raised with this, it is a whole new way of life for us and the faster technology advances, the faster we are being left behind floundering in the mess. No one stops to think that women especially in my age group were forced to resign from work when we married or had children, there was no place for us in the workforce, our place was at home, cleaning and maintaining it, ensuring our menfolk were well fed and dressed and our children were properly raised. For many women, they lost workplace skills, but the male ego was also dinted if wives went back to work, men were expected to be the providers. Unless you have lived through this period you really would have no comprehension of just how much attitudes and opportunities have changed particularly in the second half of last century, I think we have lived through some of the greatest changes ever but sadly not everyone is given the opportunity to embrace them. There are many, many people in society today, in their 60s, 70s and 80s who just don't have a clue about technology, they never had the opportunity to use it or learn about it in their younger years, but now it is just an assumption that "everyone" knows, so many seniors are really falling through the cracks, they are missing out on many benefits and are totally vulnerable to scammers. The point I make here now is that trying to follow this discussion, I realise even more what a whole new language technology seems to have introduced and how much further seniors are being left behind. I had to look up what a "dect" phone was - never heard that word used before, so many other words and terms have me floundering too, half of Ian's learned comments might as well have been written in Swahili, just where do you go to learn all this? As a senior though, (and I have many friends agree) I have a lifetime of learning stored in my grey matter, it is full and it is tired, how much more does it have to learn, how much do I really want to learn - quite frankly as little as possible, I'm over it all now. I very much agree with Pottsy's comment of putting a tin foil cap on my head, if that makes everything go away I'm more than happy. However these health issues now are definitely a great cause for concern, not just for me but I think of my grandchildren, how reliant they are on technology now, they were raised and are being raised with nothing else, what is in the future for them? I had to have my modem changed to a Smart modem recently because the original one kept failing and unfortunately I have to rely in the internet now to stay in touch with family. I also rely on regular Nanna Naps to get through the day, is this just an age thing or is it the wifi?? How will we ever know these things - obviously Daryl, your symptoms were severe enough to identify this but for someone only mildly affected ??? It is like back in the early days of mobile phones and people developing brain cancer, there were thoughts this could happen, but it wasn't like suddenly millions of people developed brain cancer and it could never be proven that people who did would not have developed it anyway. We still don't know why people get many forms of cancer, but I can understand the skepticism and cynicism - how much slower would technology advance if we really took time out to more thoroughly investigage health risks. It is great that you have identified this issue for us Daryl, but realistically where do we go from here? It is a bit like closing the gate after the horse has bolted and trying to fight telco's .............yeah!! .
