Boaz Loupe, the head of the company, says the e-radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer. So the users don't have to pay to cool their computers.

Five homeowners in Holland are testing the heating system in their homes.

"We pay for the computer using, so, in that way, homeowners get heating for free," Boaz says.
