I'm new and I live in Sydney. My husband and I are investigating to get a ducted reverse air con installed, mainly because we like to be warm in winter! (coming from overseas, we are used to central heating and since we are in Australia, we've been freezing at night in winter... I know winter is not that cold in Sydney!) Also we think it's going to add value to the house.
We had 3 quotes for ducted reverse cycle air con but 2 suggest a 12kW unit and 1 a 9kW unit. I know the guys made all the calculations so I don't understand why there is this difference in power. The guy who suggestted 9kW is sure about that and says that a 12kW unit will move too much aire and will be noisier. One of the guy who suggested 12kW says the system will struggle with 9kW only. Who should I believe? Any tips? Our house is well insulated (double brick, good windows) but we like to be really warm, say 22 degrees!
So my questions are:
#1: Have you had any experience with ducted reverse cycle? Isn't it too noisy?
#2: Do you have any advice that will help us making our mind re. 9kW versus 12kW ?
#3: I found a great brochure on heating systems (see http://www.energysmart.com.au/brochures ... system.pdf) but I'm still looking for more information especially on brand comparison. Do you know any useful websites? I found that one http://www.choice.com.au/viewArticle.as ... 100008&p=1 but you have to buy the results...
Anyway, thanks for any advice!
