Different Types of Water Heaters

Water heaters come in all shapes and sizes, and each type has its benefits and drawbacks. Here are the different types of water heaters that you can choose from.

Gas Water Heaters

Gas water heaters are one of the most popular home water heaters. They are relatively inexpensive to operate and can be used in various applications.

Gas water heaters typically use natural gas or propane to heat water, although some models may use other fuel sources. Gas water heaters are available in various sizes, so selecting the appropriate model for your needs is essential.

Pros and Cons

One of the most significant advantages of gas water heaters is their high efficiency. Gas water heaters can convert nearly all the fuel they consume into heat, making them one of the most efficient types of water heaters available. However, this efficiency comes at a cost.

Gas water heaters typically cost more to purchase upfront than their electric counterparts. Additionally, gas water heaters require regular maintenance and inspection to operate safely and effectively. Another potential drawback of gas water heaters is the risk of carbon monoxide poisoning.

Gas water heaters produce small amounts of carbon monoxide as a byproduct of combustion. This carbon monoxide can build up in enclosed spaces, posing a severe health risk to occupants. To mitigate this risk, you must properly vent gas water heaters to release carbon monoxide safely.

Electric Water Heaters

An electric water heater is a device that uses electricity to heat water. The most common type of electric water heater is the tank type, which typically holds between 20 and 80 gallons (75 and 300 L) of water. Tank-type water heaters are usually electrically powered, although some models may use natural gas or propane.

Pros and Cons

While electric water heaters are more expensive to operate than gas-powered water heaters, they have several advantages. Electric water heaters are more energy efficient, last longer, and require less maintenance than gas-powered water heaters. While electric water heaters may have a higher initial cost, they are often the better long-term investment.

Tankless Water Heaters

A tankless water heater also called an on-demand water heater, is a water heater that heats water as needed. It does not store hot water in a tank like a traditional water heater.

Pros and Cons

A tankless water heater can be beneficial in several ways. For one, it can be more efficient than a traditional storage water heater since there’s no need to heat and reheat the water. These water heaters also have a longer lifespan since no tank can rust or corrode over time.

On the downside, tankless water heaters can be expensive to install and require a higher level of maintenance than traditional storage water heaters. Additionally, tankless water heaters may be unable to keep up with demand if multiple people try to use hot water simultaneously.

Storage Water Heaters

A storage water heater often called a hot water tank, is a tank that stores water and heats it. Hot water tanks are usually natural gas, propane, or electric. The most common size for households is 50 to 60 gallons.

Storage water heater efficiencies range from about 60% to 70%. That means that for every $100 spent on operating costs, $60 to $70 goes to heating the water.

Pros and Cons

Storage water heaters have a tank that holds a certain amount of water. The water is heated and kept in the tank until it is needed.

One of the biggest pros of storage water heaters is that they are very reliable and can provide a large amount of hot water when needed. However, one of the biggest cons of storage water heaters is that they are not energy efficient.

Solar Water Heaters

Solar water heaters are a type of solar thermal system. Solar water heaters use the sun’s energy to generate heat. This heat is then transferred to water stored in a tank.

Solar water heaters are a great way to save energy and money. They are also a great way to reduce your carbon footprint. If you want to install a solar water heater at home, check out

Pros and Cons

One of the biggest pros of solar water heaters is that they can save consumers a lot of money on their energy bills. Solar water heaters can significantly lower the cost of heating water, which can significantly affect your monthly budget.

However, it would help if you also considered some cons of solar water heaters. One of the biggest drawbacks is that they require a significant initial investment.

Solar water heaters can be expensive to purchase and install. For that reason, ensuring that long-term savings will justify the upfront cost is vital.

Another thing is that if there is no sun, the water will not be heated. You will need a backup water heater to ensure you always have hot water, even on cloudy days.
