Resolving Your Hot Water Problems - Water Heater Applications

By: John Philips

When it comes to energy consumption in the home a water heater ranks just behind air conditioners and furnaces so when making a choice a gas model answers your efficiency and economics needs. Coupled with energy efficiency, gas water heaters are also time efficient, heating water twice as fast as electricity, less expensive to run and are faster at heating a tank of water than all other forms of energy.

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.

Propane and electricity however cost too much to be used extensively for heating water. Because gas water heaters are more efficient than electric because you can heat more water faster as the burners are capable of higher temperatures than electric elements. The water heater receives gas through a valve in the wall. Buried underneath the tank of the water heater is the burner that heats the water.

The design of the heater allows for the presence of a thermostat to sort of keep an eye on the temperature right inside the device. A pilot light or a spark lights the burner up. A close look at a gas grill will reveal a similar process. Exhaust fumes are expelled from the system by a vent above the tank.

Emissions are channelled out through the PVC pipe, an essential part of the vent. Later models of the gas water heater are equipped to pass out toxic emissions through a wall under the influence of pressured air supplied by an accompanying fan. Fluids supplied to the water heaters are gas and water. Only after the water has been heated in the cylindrical tank is it supplied through internal pipes to the taps through which it can be used.

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 workings of a water heater without a tank take some understanding. Their ability to supply endless hot water at any needed time makes them stand out. The energy input to output ratio of a tankless water heater is also impressive. Much larger gas requirements are needed for tankless water heaters are than for storage water heaters.

Unfortunately, it does not begin to heat the water until the tap is turned on, so it takes longer to heat. A gas heater without a tank cannot hold water to any capacity. The water is instead routed to the faucets and appliances that are in need of the heated water.
