We are intending to build with Coral. We have a choice between gas, solar or a heat pump for our hot water.
Gas is apparently standard, the heat pump will cost us around $900 - some 'promo' they have, but I am also interested in solar. I would like to know more about the costs, not only of solar water but also to generate some of our power needs if possible?
I am so confused. I have treid comparing but confused myself! Has anyone compared these 3 methods for heating water & which one do you reckon will end up giving us some $ savings - keeping in mind our current hot water (electric) is usually around $70 a quarter?
Cheers
Kim
