Even though water heaters are generally very reliable and are usually one of the most dependable appliances in the home, occasionally they may have problems such as rotten egg odor, rumbling and popping noise, high pitched whining sounds and leaking issues that can result in loss of hot water.
Gas water heaters and electric water heaters are very similar in their shape and size but are different on how they operate. Both water heaters use an insulated storage tank jacket that is made of steel and is insulated between the storage tank and the tank jacket to reduce the heat loss of the hot water. Gas water heaters use a gas burner similar to a gas stove and furnace. Electric water heaters use an upper and lower heating element similar to an electric stove and oven.
Gas water heater components include a standard tank, a cold water inlet pipe with a shut off valve, a gas supply line with a shut off valve, a temperature/pressure relief valve, a gas burner/pilot control valve, a gas burner at the base of the tank, an overflow pipe, a drain valve, a hot water outlet pipe and a flue at the top of the tank for breathing purposes. As the cold water enters into the bottom of the tank through a dip tube, it is heated up by the gas burner, as the water gets hotter it rises towards the top of the tank thru the convection process. The water is than drawn out by the hot water discharge pipe located at the top of the tank to ensure that only the hottest water is being drawn out from the tank.
Electric water heaters utilize a lower and upper pair of metal heating elements to heat the water. The lower heating element is the work horse of the two since cold water is distributed at the bottom of the tank. The upper element is used when there is an increased hot water demand and only heats the water at the top of the tank. If you have a constant supply of lukewarm water while taking a shower, that is an indication that the upper heating element is defective and needs to be replaced. If the water is hot and suddenly turns cold, that is an indication that the lower heating element is defective and needs to be replaced. The replacement heating elements must be the same style and voltage/wattage as the old ones that are being replaced on the water heater. Texas Home Contractor highly trained professionals are experts in diagnosing and replacing defective electric water heater elements.
To significantly increase the life of your standard tank style water heater simply dial down the temperature, test the temperature/pressure relief valve and flush out the tank periodically.
Tankless water heaters create water on demand rather than store hot water like standard tank style water heaters. Tankless hot water heaters are a fantastic solution to residential hot water needs but are more complicated than tank models. They are manufactured in point-of-use and whole house- versions and are fueled by electricity, natural gas or propane gas. A point-of-use system is designed to supply hot water to a specific location like a sink, a shower or just to heat up a cup of tea. Whole-house versions are designed to supply several bathrooms and the kitchen with hot water. Since tankless versions do not have a storage tank and supply hot water on demand there is no standby heat loss, therefore making them more energy efficient. Standby heat loss is the energy and heat lost in the storage tank while the hot water is not being used. Point-of-use and whole-house systems basically operate identically. Cold water enters into the unit than a flow activated switch turns on the heat exchanger. The heat exchanger can be a gas fired burner run by natural or propane gas, or can be an electrical heat coil. Whole-house units are typically gas fired since they have a larger heating capacity and may use multiple heat exchangers.
This is measured as the flow rate in gallons per minute (GPM). The more plumbing fixtures that you want to serve the higher the necessary GPM.
The ground water temperature in a specific area has a huge impact on the size of the unit necessary to supply the correct amount of hot water to the home.
You must determine the temperature rise of the unit which is the difference in the temperature of the cold water entering the unit and the desired temperature of the hot water leaving the unit.
The Federal Energy Policy Act of 1992 required all faucets and shower fixtures made in the USA to have a flow rate of not more than 2.2 GPM at 60 PSI. Fixtures manufactured before 1992 have a flow rate much higher than 2.2 GPM. You have to add up the flow rate of all the fixtures that you want to service with hot water and size the tankless hot water heater accordingly.
Electric tankless systems require at least 2 new 240 amp breakers run directly from the distribution panel to the tankless system. If you’re existing distribution panel does not have the capacity to carry these new breakers you will have to upgrade your distribution panel to at least 150 amps
