Heat Recovery from Dryer Exhaust
Are there _no_ heat recovery products on market to recover the energy blown out of dryer vents?
I found 2 prototypes online from the mid 2010s. One looks similar to standard heat exchangers, like HRV/ERVs.
One on Build It Solar (a DIY site I like:)
An another random one:
The 1st link has more data, including an estimated 32% energy recovery.
I find it odd that we talk about heat pump dryers, drain water heat recovery, etc. but still have no product on the market to take the humidity out of dryer exhaust so we can actually re-use the hot air in wintertime: either to pre-heat air intake back to the clothes dryer, or to help heat a conditioned space. No? O.O
