Jimbo, I recall a few discussions about Evaporative Cooling, and I think the outcome was that reverse cycle heat pump was better..
As for heating.. if you were considering RAC cooling, then that solves your heating needs, provided the bride is not like mine and "finds" it just too dry..
I had wondered, how a combination of a small LPG and RAC would go... Unflued LPG, releasing moisture..
And don't jump down my throat about Unflued gas and LPG... I have used it all my life, and my brain is as good as the day I was born.. just never got any better
