water heat exchangers boiler

How do heat exchangers work? - Explain that Stuff

What is a heat exchanger? Suppose you have a gas central heating furnace (boiler) that heats hot-water radiators in various rooms in your home. It works by burning natural gas, making a line or grid of hot gas jets that fire upward over water flowing through a network of pipes. As the water pumps through the pipes, it absorbs the heat energy and heats up.

2020 Boiler vs. Furnace Guide | Hot Water or Forced Air

Steam and boiler heating systems are among your heating options in cold climates. Put simply, boilers send hot water through a system of pipes that can heat your floors, walls, or baseboards through radiant heat. Radiant heat essentially radiates heat into the room. There's far less energy waste compared to forced air and keeps the air more
