Water Heater Principles - By: John Philips.., Posted on: 2007-08-11

The second largest cost of energy next to heat/air conditioning systems in the home is heating of water and whether your home uses electricity, gas, or liquid propane gas, water heaters are designed to help you meet the hot water demands of your household. Although water heaters are available powered by gas, oil or electric-fired devices that heat water for residential or commercial use, but gas heaters tend to be more popular for larger flow rates.

The water heater is a device that is used for the purpose of heating water to convenient temperatures. Similar to boiling water by stove, the water heater infuses heat into the water as transferred from a burner.

Nine out of ten water heaters run on natural gas. Ready-made energy like electricity can be used to run a water heater, as can organic propane. Heating water in any case costs a lot more than is wise to spend if you're using electricity or the petroleum by-product propane.

Warming of water in the gas heater is achieved by heat being transferred from the burner in its isolated position below the tank of the water heater. Opening a valve on the wall close to the heater is the action that permits the pumping of gas into the heater to power it. The water tank also contains a thermostat that senses water temperature and thus controls the flow of gas into the heater to regulate the heat.

The whole of the heating depends on a pilot light that brings the system alive. A good example of this process can be found by closely watching a gas grill. The combusted gas fumes find their way out of the heater through a venting system. The roof of the heater is fitted with a PVC pipe that completes the venting system.

It should come as no big surprise to learn of the innovation that allows for fan-assisted toxin emission systems on gas water heaters. The supply of cold water is made possible by a pipe linked to the heater. Pipes in the system channel heated water to its final point of use through faucets or valves.

Some tanks actually do not have a water storage system. Due to the absence of a tank, the water has to be run through several burners continuously until it is needed for its final application. Gas water heaters that do not have tanks work in a slightly different way from those with tanks.

One such difference is that this design enables it to supply heated water endlessly. Being an improvement on the old prototype, manufacturers made it a prerogative to save energy with the new heater. The one flaw of this design is the length of time it takes for the water to heat up as heating does not begin until the tap is opened. Water is stored in the tank of a gas heater, meaning that a tankless heater does not have the means to do so. Heating of water is all that a tankless gas water heater does, in addition to passing the heated water along to appliances for consumption.
