Raising The temperature Of Water - Benefits Of The Water Heater - By: John Philips, Posted on: 2007-08-09

When it comes to deciding on a water heater for the home it should be realised that they rank a close third behind air conditioners and furnaces for energy consumption. Gas water heaters, because they are faster at heating a tank of water than all other forms of energy are more energy efficient and time efficient than all other forms of energy and can solve some of your efficiency and economics needs.

In a water heater, heat energy is forced into water. Water in a water heater is heated in a similar way to water in a pot placed on a burner. Natural gas is the fuel used to run several water heaters. Propane and electricity can also be employed to power some water heaters.

The least expensive fuel for water heating purposes is however natural gas. Because you actually make a flame when you burn gas they are more efficient at heating more water faster than electric because the burners are capable of higher temperatures than electric elements. The water in the tank is warmed up by the heating element known as a burner sequestered under the tank. Attached to the wall is a valve that can be opened to let in gas to the heater, or closed to stop the flow.

To avoid overheating, a thermostat is installed inside the water. The gas is ignited by the pilot flame or electronic ignition, creating a round pattern of burner flame for even distribution and transfer of heat to the water. A spark is used to light up the burner. The igniter in a gas grill adequately illustrates this.

It is necessary to have something like an exhaust system to get rid of toxic emissions. A PVC pipe is a vital part that crowns the venting system, through which emissions are sent. In modern day, technology has enabled the development of water heaters that use fans in conjunction with their vents that pipe out exhaust through a wall. Be informed that water heaters powered by natural gas also have an additional pipe that supplies cold water.

Some manufacturers have gone as far as to create a tankless version of the water heater. In a tankless water heater, the appliance also receives heated water via a faucet, but only after it has been cycled through several burners. The operation of a tankless heater is different from that of the regular gas water heater.

The absence of a tank results in water being able to flow continuously through the system. They are also imbued the ability to maximize their energy input. Tankless water heaters, however require much larger gas requirements than for storage water heaters.

If you are someone always in a hurry, a tankless heater may not be appropriate since the water does not start heating until the faucet is turned on. A tankless heater has a zero storage facility for water. In the case of tankless heaters, the water, after being heated is only routed through the heater to the faucets for eventual use.
