I just installed a FiWi HEX radiator to a FiWi heat recovery ventilation unit which is connected to the 40m2 Solar Roof heating system in a house we are renovating to Passive House standard. I'm looking at a second FiWi HEX rad in my office for another project. I will pump 30 degree Celcius drain-back solar water through the FiWi HEX rad to heat the house.
