Heat Pump Water Heater and Humidity

Wondering how RH effects the COP of HPWH.  I'm installing an add-on unit (Geyser) and want to duct it into the living space, for summer cooling.  The master bath is directly above the mechanical room, how will this potential high humidity effect the evaporator's ability to absorb heat from the air?  I was thinking this would be better?

Humidity is heat

Latent heat. So the more humid the air into the heat pump, the more capacity.

BTW

But, are you sucking air out of the bathroom or blowing cold air into it? If blowing in, where does the air come from? If mechanical room, is there any fuel appliances in it?

Pulling air from bathroom

and ducting it to the master bedroom, which is on the other side of the partition.  Basically the unit will be in the mechanical room below the floor, pulling air from bath high in partition wall and them pushing the cooler air into bed via floor register. 

I figured the humidity was latent heat as the phase change would condense the water out and yealdmore heat driving the COP up.  We in this part of the country are just beginning to get into HP tech, so I want to have learn as much as I can.  Install as well and efficient as possible



Thank you!

Wow

That's going to be an interesting smelling bedroom at times

Stink ducting.........

Nah, I only stink up the 1/2 bath downstairs.  That bath is for showering and going #1 only for me. LOL

Solid fuel

So the solid fuel stays downstairs, huh?

Not that type of fuel..........

Haha, biomass is my game.
