This video made me realize that heat pumps are very “hackable” and open to DIY. Even out of the box, this particular unit is super impressive. It has a COP of 2-3 (i.e., it is 200-300% efficient) for heating, 4-5 for cooling. I bought one online for ~$1000USD. It showed up on my porch a couple of days later. I plugged it into a 110V outlet, hooked up a dual hose duct adapter to a window, and my gas furnace hasn’t fired up since it’s been plugged (we’re currently in the middle of a cold Canadian winter).
Anyone actively working in this space?
UPDATE:
This $1000 heat pump could not keep up with the demand <-10C. It is still supplementing the gas furnace for now, but I’m not ready to cut off my gas line yet folks
