Abstract
An illustrated view of an improved anode rod assembly for removing corrosive elements from the water of the tank. The improved anode rod assembly is useful for providing a longer life span for water heater units. Further, an illustrated view of an exemplary water intake assembly is presented. The water intake assembly is useful, it provides an extra port so that more anodes can be inserted into the tank. Also having the dip tube at the very bottom of the tank provides more hot water and increases the efficiency of the water heater. Having multiple anodes will give an indefinite life span for the water heater.
Description
- This invention relates to a water heater. More particularly, it relates to providing more cathodic protection for the water heater unit which will increase the efficiency and life span of the water heater.
- Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.
- Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. Rarely, hot water occurs naturally, usually from natural hot springs.
- Appliances that provide a continual supply of hot water are called water heaters, hot water heaters, hot water tanks, boilers, heat exchangers, or calorifiers. These names depend on region, and whether they heat potable or non-potable water, are in domestic or industrial use, and their energy source. In domestic installations, potable water heated for uses other than space heating is also called domestic hot water (DHW).
- Fossil fuels (natural gas, liquefied petroleum gas, oil), or electricity are commonly used for heating water. Electricity to heat water may come from any other electrical source, such as nuclear power or renewable energy. Alternative energy such as solar energy, heat pumps, hot water heat recycling, and geothermal heating can also heat water, often in combination with backup systems powered by fossil fuels or electricity.
- Water heaters have cathodic protection to make the water tank last longer. Cathodic protection is done by inserting a sacrificial metal called an anode that will be consumed by the corrosion that occurs from the minerals in the water that enter the tank. So that the metal of the water heater tank will not be harmed.
- The anode protrudes into the tank about ¾ length of the tank, in the center and full length of the anode is a small core which is made of a steel rod which the sacrificial metal is attached to. The anode is inserted into the water heater tank top and has a cap that attaches it to the tank.
- Water heaters have a dip tube which is installed in the port that is on top of the water heater tank where the cold water enters. The dip tube is a hollow plastic tube. The purpose of the dip tube is to divert the cold water that enters the tank to the lower part of the tank.
- A concerning issue is that the anodes made of a sacrificial that are consumed quickly and have to be replaced every 12 to 18 months.
- Accordingly, in light of the above, there is a need for a device that will allow for more anodes to be placed in the water heater tank so that anodes will last for 60 to 72 months or longer before replacement is needed.
