What Are Water Heaters?

Water heaters are used to heat water for household and commercial use. The majority of water heaters in the United States are fueled by natural gas or electricity, while solar water heating is common in Europe and gaining popularity in the United States. Water heater tanks usually range from 50 to 200 gallons (189-757 liters) and capacities of 100 to 300 gallons (378-1,136 liters) are becoming more common. Water heaters can be fueled by propane, oil, or solar energy.

Water heaters come in two types: tank-type and tankless. Tank-type water heaters have a storage tank that heats water and releases it when needed. Tankless water heaters only provide hot water as it is used, so they can save energy if you have a low demand for hot water.

Water heating accounts for about 18% of the energy use in a typical U.S. home, making it the third-largest energy expense, after space heating and cooling. Water heating can account for up to 34% of the annual electricity consumption in an average home.

Why Are Water Heaters Important?

The average American household spends around $2100 a year on energy expenses, and about 10% of this is attributed to heating water. More than 5 million gallons of hot water are used daily in the U.S., and it’s important to make sure that the water heater doesn’t cost you more money than necessary. One way to do this is by keeping the water heater’s anode rod(s) in good working condition.

An anode rod is a sacrificial bar that helps to extend the life of your water heater because it corrodes instead of the metal tank. Water heaters can corrode from within, and if this happens, you’ll need to replace them sooner than usual. Water heaters usually work for about 10-12 years before they start showing signs of corrosion and will need to be replaced. Water heaters with stainless steel tanks tend to last longer than those with enameled tanks (9-11 years versus 6-8 years). The reason why has to do with different types of corrosion protection; stainless steel tanks better protection against corrosion while enameled tanks can chip and peel.

Anode rods are easy to replace and only cost a few dollars, so it’s a good idea to check on them every year or so to make sure they’re still in good condition. If they’re not, replacement is an easy process that can be done by most homeowners. Water heaters are an important part of any home, so keeping them in good condition is essential for minimizing your energy costs.

Water Heaters: How They Work

When you turn on the hot water in your home, the water heater goes to work heating up the water that flows into your faucet. Water heaters are an important part of any home, and because they provide hot water for showers, sinks, dishwashers, and washing machines requirements vary depending on the size of the household. Water heaters vary in both energy efficiency and capacity (measured in gallons).

Water Heaters: Anode Rods

Water heaters also contain a special metal rod that acts as a sacrificial agent that corrodes instead of the metal tank. This protects the tank from corrosion and therefore extends its life. Because water heater anodes help extend your water tank’s lifetime and prevent leaks and cracks, it’s important to keep them working properly by replacing them regularly. Water heaters usually work for about 10-12 years before showing signs of corrosion will need to be replaced. Water heaters with stainless steel tanks tend to last longer than those with enameled tanks (9-11 years versus 6-8 years). The reason why has to do with different types of corrosion protection; stainless steel tanks better protection against corrosion while enameled tanks can chip and peel.

Water Heaters: How the Anode Rod Works

Water heaters contain metal rods called anode rods, which can be made from magnesium or aluminum. These rods are attached to cables that connect them to the heating element in your water heater. The chemical reaction between the hot water and the anode rod creates bubbles of hydrogen gas, which protects the inside of your tank by coating it with a layer of an insoluble oxide film. As the anode rod corrodes, it slowly dissolves and replaces the film. If the anode rod is not replaced regularly, it will eventually corrode away completely, exposing the tank to corrosion. Water heater anodes are easy to replace and typically cost only a few dollars, so be sure to check on them every year or so to make sure they’re still in good condition. If they’re not, replacement is an easy process that can be done by most homeowners.

Water Heaters: Tankless vs Conventional

Water heaters come in two types: tankless and conventional. A tankless water heater doesn’t use a traditional storage tank; instead, it heats water as it’s needed. This type of water heater is more energy-efficient than a conventional water heater, and it can save you money on your energy bills. However, tankless water heaters are more expensive to install and may not be suitable for larger homes. A conventional water heater uses a storage tank to store heated water, which is then released when needed. This type of water heater is less energy efficient than a tankless water heater, but it’s less expensive to install and is a good choice for larger homes.

Which type of water heater is right for you? That depends on your needs and budget. If you’re looking for an energy-efficient option, go with a tankless water heater. If you’re looking for a cost-effective option, go with a conventional water heater.
