There are a variety of residential gas water heaters available for use in homes. This is one of the most common residential type of water heater. They are preferred by many because they can heat the water twice as quickly as an electric water heater.
These water heaters are not as costly as electric water heaters, although they are not quite as efficient. However, due to electricity being more expensive than gas, the cost is less to heat water with residential gas water heaters.
Residential Gas Water Heaters – Cost Effective
Rheem makes several models that are popular such as the 22V40F1 and the 22V50F1. The models are a 40-gallon model and a 50-gallon. These two residential gas water heaters are virtually maintenance free, which is one of the reasons for their popularity.
In addition, as with most newer models today, they have safety features that automatically shut them down if there is a problem detected.
Advantages of Residential Gas Water Heaters
When purchasing a residential gas water heater, there are a few features that people look for that are considered advantageous:
- TPR Valve – This is also known as a Temperature Pressure Relief. Many electric models also have this feature although there are some tankless models that do not. This safety device is important for the water heater being purchased in case the pressure or the temperature gets too high.
- Anode Rod – The best type available in residential water heaters is a sacrificial anode. This metal rod is typically made of aluminum or magnesium and electoslysis eats away at the rod rather than the inside of your tank. This prolongs the tank life. Keeping check on the anode rod can keep corrosion from occurring in your tank.
- Dip Tube – This is necessary to direct the cold water that comes into the bottom of gas residential water heaters. This stops cold water from mixing with the hot water that is going out. If the dip tube is broken, you can experience less than hot water and often the hot water will not last very long.
- Drain Valve – The drain valve is important for a variety of situations. The residential gas water heaters need to be drained approximately every six months. This keeps sediment from building up in the tank especially in areas where the concentration of minerals in the water may be rather high.
Disadvantages of Residential Gas Water Heaters:
What are the disadvantages of residential gas water heaters? Just as many people prefer electric water heaters as there are those who prefer gas water heaters. The disadvantages that have been reported are:
- One of the main complaints of those who have switched from electric to residential gas water heaters is the need to connect a gas supply to their home. For many, this is not available and the only choice is to use propane or LP rather than natural gas. If you are switching from an electric water heater, you may want to ensure that gas is available before making the choice.
- Some people say that gas water heaters are slower than electric water heaters when it comes to heating water. Others say the opposite.
- Using a natural gas water heater will produce more heat in the area where the water heater is located than an electric water heater. In addition, there are CO2 emissions from a residential gas water heater.
- Most residential gas water heaters are smaller than electric water heaters. When using an electric model to fill a bathtub, there is still water in an electric tank that is part heated water and part cold water that is replaced as the heated water is used. This allows the water in the tank to be heated by the time the tub is filled instead of being left with all cold water.
- One fact that cannot be ignored is that natural gas releases carbon monoxide. With more efficient models, there is less and many manufacturers say their gas water heaters meet the acceptable levels; however, the carbon monoxide is still released into the air. With the concentration focused on clean energy today, the use of a gas water heater still pollutes the air.
These are just a few of the advantages and disadvantages of residential gas water heaters versus electric. The choice of which type to use still remains a matter of preference. Have a look at other popular reviews of Water Heater Reviewer
