The idea of a water heater first emerged in London in 1868, when a painter figured out how to heat cold water by placing gas burners at the bottom of the water pipes. This inspired a Norwegian mechanical engineer, Edwin Ruud, to create the first tank-type water heater and bring the idea to Pittsburgh, Pennsylvania.
Exploding Water Heaters
The myth of the exploding hot water heater is rare, but true. While it’s possible for a water heater to explode, there are simple ways to prevent it. These include regulating the temperature and psi as well as checking for rust and smells of leaking gas.
Caution must be taken around water heaters; human skin can suffer third-degree burns in less than fives seconds if it comes into contact with water that’s 140 degrees Fahrenheit or higher.
North America: “tankless hot water heaters” or “on-demand hot water heaters”
The U.K.: “multipoint geyers”
Australia and New Zealand: “instantaneous hot water units”
