It’s great, it’s extremely comfortable and it’s a very elegant form of living. We’ve found, you don’t really notice temperature variances at all and if you do notice a slight warming or cooling it happens very gradually, adding to that the lack of condensation, mould, even dust, it’s really just an incredible way to live.

Everyone who’s come to the house has noticed it as well, especially people in the building industry, because they know what a modern house can do and this is really just many, many times better than anything they’ve experienced before.
Our electricity bill is only $100 a month at the peak of winter, that’s just an amazing result, that’s everything - heating, lighting, cooking, hot water.
