Giant Heat Pumps Are Giving Big Buildings Hot Water Without the Smoke!

Have you ever wondered how a huge apartment building or a busy hotel gets endless hot water for everyone's showers at the exact same time? For decades, buildings burned fossil fuels like gas in giant metal boilers. But now, clean tech called central heat pump water heaters is booming!

A heat pump doesn't make heat by burning anything. Instead, it works like a backwards refrigerator. While a fridge pulls heat out from inside its box and dumps it into your kitchen, a heat pump pulls warmth out of the surrounding air and squeezes that heat directly into cold water tanks.
