Hi,
This topic is awesome! I just registered because this topic so I can answer here.
I have read all this topic planned to make DIY HRV already 1.5years ago, I have bought motors and RECAIR heat exchanger core (160 model, 300mm thick) and now I started to make box for it. I live in Estonia and it is cold country, february was mostly -10...-15 degrees celsius, peak was -25C at some nights.
Few questions to people who have done it already:
1) how you have resolved defrost - what strategy are you using? What options are available?
2) Is it best to put both motors in warm side (stale air out, prewarmed fresh air in)
3) Kostas - You made air humidifier, do you still use it? Please give more details about it - does it help, are there any issues?
