Water heaters are not the sexiest of appliances. They certainly don’t inspire song or poetry. And no-one would choose one to become their muse. But as the second biggest energy guzzler in your home, it’s important we know at least enough about them to make a smart choice. GE has come out with two new water heaters: the tankless and the hybrid electric. They have a great video explaining the functions of each — which means no more hiding behind illiteracy to shroud environmental ignorance.
