DIY ventilation heat exchanger

Hi, I was checking links to my website and found this forum, its been interesting reading!
I build Passive Houses in Ireland and the UK and we make our own HRV units that fit completly into the external wall. We fitted close to 50 units this year and they seem to be working well with higher return air temperatures than some of the PH Certified Paul units. We use Copper fine-wire heat exchangers that have 20km of wire in each heat exchanger.
