Want to install a new MSHP and you are thinking about
where,
the ODU (outdoor unit) should be located?
AND,
You have a large attic space, that gets really warm during cold winter days,
and would like to harvest some of that heat..
(Maybe you don't have enough south facing windows)..
Here's an idea that I had. Insulated duct work, to pump air down to
the mini-split air-intake, using a standard attic fan..
Just need to control the motor, so it's not running when you don't need it.
The sweetest part of this hack, is you are re-cycling some of the heat that was lost via ceiling leakage..
Sorta like a solar space heating +
heat recovery system..
