Hi All,
A while back I discovered that the HX-core in my HRV is not as efficient as I expected it to be and I found the cause. It comes down to the choice of material.

I think 2kW or so is too much.
Asuming 70 m^3/h and 80% efficiency and inside temperature of 20C, fresh air 0C you need to heat the air something like 4C (7F). (You intend to preheat the incoming...

Indeed it's quite simple: E = m * g * h
E = energy (measured in joules)
m = mass (in kilograms)
h = height (in meters)
g = gravity acceleration (about 9.81 m/s^2 (at sealevel), often rounded to...
