A good solution for the right house
The transfer system itself looks good (I haven't yet got it going) with a reasonable quality fan and digital display. There is only the one splitter (200mm to 3 x150mm) where two seperate splitters are more useful. Also the 150mm ducts are only 3m in length which is actually too short for most houses. So, yes, it will work well if you have short distances and a compact style house. Needs an electrician- no plug in wire.
