The air supply and exhaust are planned to be installed directly in the exterior wall (basement wall of the utility room) and fitted with light wells.
I read on the Pluggit website that frost can cause problems because the cold incoming air can freeze the condensate in the heat exchanger, which reduces the air supply and causes the system to shut down.
What low-cost options are there to prevent this? Pluggit's pre-heating system warms the outside air before it enters the unit. That would be fine, but at 900W power it uses a lot of electricity. Alternatively, could the air supply be installed not in the basement wall but through ducting 1-2 meters (3-6 feet) deep and 4-5 meters (13-16 feet) long into the garden, with a small air intake block set up there? Would that also work? I just want to avoid high costs.
