  • How Wood Pellets are Produced - Modern people who are concerned about the impact that they are having on the environment are turning more and more often to the clean burning and fuel efficient biomass stoves, which burn fuel like wood pellets at a very high heat, allowing a small stove to heat a room very well. These pellets cost less than other sources of fuel, and burn very cleanly, which is much better than coal can do. Wood pellets are relatively small, shaped almost like a gel capsule type of pill. They are shiny, which adds to the pill illusion and makes them look almost like small, varnished pieces of wood.

For our example we will use a gas heater, because it is easier to visualize than electric, but it’s pretty much the same for an electric model as a gas model. A tankless water heater can be pictured as a coil of pipe over a campfire. As you run water through the pipe, the heat from the flames gradually heats the water in the pipe, and by the time the water has gone through the entire length of pipe it is hot. The more slowly the water travels through the pipe, the hotter it will get.
