I am interested in this unit. I know it has limitations, and cannot be used soley for heating, and supplemental heating is required. We have no air conditioning at all, and this would give some free cooling by air exchange. Our house meets the criteria in all aspects by being 90m2 weatherboard, north face roof, roof cavity, on stumps, well insulated etc.

Anyone have any experience in operation and potential outcomes of heat and air exchange cooling?
