Their FAQ says it can still work when you don't need the heat in the house:

> Will the Nerdalize Heater work during the summer?

> Yes. Our Heater can expel excess heat to the outside when the homeowner does not require heating. This way we can compute at full capacity during winter and summer utilizing our hardware optimally.

That suggests, however, that installation is more complicated than just mounting it on a wall like you would a shelf or a picture frame and plugging in power and network. It sounds like you'd need to have something going through the wall to the outside.

They're essentially using your cooling in the summer unless it does air intake from the outside too.
