I am so glad of this thread cos we are going through the same decision. Any thoughts about choosing HRV vs. DVS vs. Moisture Master? I don't like the sound of 'cold drafts' that supasi mentioned. Do you get that with HRV? Our house is a small (95sqm) 3 bedroom house, and we have a flued gas heater in the living room but the bedrooms, especially the one which doesn't get sun, are FREEZING. Stuff on the wardrobe floor gets mouldy, ceilings get mildew spots. Do we need HRV and a heat pump??
Sorry to hijack just desperate for some help in this area!
