Water Heating System
The water heater is used to provide hot water for the kitchen, bathroom, and washing is based on the principle of convection. A heater coil mounted on the boiler so that the water in the kettle it through freely. When the coil is heated water in it to be warmed by the heat flow through the metal wall of the coil is by conduction.
The water was rising through the coil and flows to the top of the kettle. At the same time the cold water from the kettle down to the bottom of the coil. Tempers convection currents. In time, all the water in the boiler will be heated. The hot water is taken to be used from the top of the boiler and replaced by cold water that is channeled to the base of the tank. The water once again heated.
Air Heating System
the convection currents occur in the air similar to the way the the convection currents in the water. However, the flow of the convection currents in the air is much faster than the flow of the convection currents in the water. The difference between water and air is that the air is much lighter, easier to move, and the more expand when it is heated.
the convection currents of air flowing through the chimney when a fire is burning in the hearth. Before the fire was lit, the air in the chimney has a density equal to the air outside the chimney. But soon after the fire is lit, the air above it becomes warm and expand. Due to being lighter, the air will rise to the top of the chimney.
The cold air outside fireplace flows to the bottom of the chimney. urged the hotter air above it. Hot air rising in the chimney is part of the rising the convection currents. The part that down from the air flow is around the chimney. the convection currents flow can be reduced by partially closing a valve. Thus the use of fuel for the hearth can be arranged.
A high chimney suck better than a short chimney, which is due to stronger the convection currents occur in it. The higher the chimney, the greater the weight difference between the chimney gas column in the same column of the outside air, and the more effective the cold air down to chimney and can push more cold and heat air up.
so air heating system with a hearth not make the air becomes warmer, but suck cold air to come out through the chimney
