Hi people, it's been a while since my last post, after many months of hard work I finished what I call the first version of my complete DIY HRV home system. As I previously said I wanted full-house ducting with outtakes in the livingroom and bedrooms and intakes in the bathrooms and kitchen. That meant lowering 13cm the whole ceiling of the first floor, some 45sqm of drywall done in aprox 10 days work there... By the way I also installed new recessed LED lighting and an also recessed VPR motorized housing with motorized screen and HT sound system. I finished the first floor last August (2014) and the rest of the ducting by February of this year. The HRV is rocking since then and, even if the winter wasn't very cold this year, the inside comfort is superb! No more window opening, no more cooking odors on the second floor, no more steamy mirror while taking showers! Last but definitely not least, you get all that fresh air during the sleep, which is priceless.
