Hello. I found a new type of heat pump, "ICE-STICK" type. I didn't heared until today about this technology.
I tried to post a link but the RE forum didn't allowed.
Anywhay, Octopus Energy AB produces this kind of HP's.
It's a new technolgy?
I can't understand how ice melts in order to form new ice, keeping in mind that the HP only works when ice si building up around the "sticks"
