Applications Of Water Heaters
by John Philips
Water heaters are designed to meet the hot water demands of your household and the heating of water is considered the second largest cost of energy next to heat/air conditioning systems in your home. Whether your home uses electricity, gas, or liquid propane gas there is a water heaters designed to suit. Gas, oil or electric-fired devices are all available for residential or commercial use, but for larger flow rates gas heaters tend to be more common.
The temperature of water is raised by heat energy that is infused into it by the water heater. The principle of operation of the water heater is simply that of heat transfer from a source to a sink, where the water acts as the sink, and the gas is the source of energy.
Gas released from the bowels of the earth with crude oil contains a lot of energy, some of which is harnessed to run a water heater. The energy stored up in propane and electricity can also heat water under certain conditions. The scarcity of propane and the cost of electrical energy generation neutralize their cost effectiveness in powering water heaters compared to natural gas.
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 ignition is done by a pilot light. The device known as the gas grill is a fair enough illustration of how this works. It is imperative to have a vent system installed as part of the heater to relieve it of burnt up fumes. To complete the vent is the PVC pipe seated firmly on the roof, receiving and discharging the used up fumes.
The heater is now improved to such a point that a fan that forces fumes out through the wall supports its venting system. Gas is not the only non solid component that works with a gas water heater; water does too. Appliances receive water from the cylinder shaped tank through the pipe network and water valve system attached to the water heater after the water has been heated.
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.
Hot water supply is endless in a tankless water heater. The energy efficiency of a tankless water heater may actually surprise you. Tankless heaters start heating only when the water valve opens. Since storage is done in the tank, the absence of a tank in the tankless version also means the absence of storage. Manufacturers have only fashioned this tankless heater model for heating of water before eventual use.
