Heat recovery
Yes i have its been working for a couple of years now. I have the photos uploaded into this forums albums but i cant load into this link yet.
Here is some more info about the project , the controller is a Highway differential controller with a onboard thermistor and a remote thermistor on light speaker cable about 4 metres away. Its in the apex of the roof for efficiency , the filterd inlet is somewhat , i put a gooseneck in the insulated ducting (100mm 4 inch) so there should and i have checked no reverse thermosyphoning. The motor is 240V and uses 60Watts.The Filter , and fan helps or adds to that also in a small way. There is only a 1 C differential setting on the controller. The roof is Metal and has a 33 ' fall/pitch . Its most efficient in the Autumn and Spring and occasionally on sunny Still winter days. So it maybe 19C to 24C-34C ,66F to 75F-93F. This is typical spring autumnal equinoxes temperatures. 1st number is room temp and the other 2 attic temperatures.
Also it does push fresh air inside as half the solution and really works .
