Hot Water Heating Systems: Transitioning from Gravity

Hot water systems have long been a preferred way of transferring heat from a central point (a boiler) to remote spaces or rooms where heat is needed. The first hot water heating systems were gravity systems. When water is heated, it increases in volume; hence it becomes lighter and rises. Simultaneously cooler, heavier water falls. This is the principle on which gravity

The Difference Between Boilers And Water Heaters

Depending on how much you turn your hot water handle, the water heater will "send" hot water, which will mix with the cold water, to your sink or shower. This is done through the pressure in your pipes - as the sink or shower is turned on, cold water is put into the water heater, moving the warmed water into the pipes and to your faucet.
