Electric Water Heaters

Electric water heaters are one of the most popular and economical options for heating your home with hot water. They are highly energy efficient, cost effective, environmentally friendly, easy to install, and come in many shapes and sizes.

There are two types of electric water heaters: tankless and tank. Tankless heaters don’t use a storage tank and instead heat the water as it’s used. Because there’s no storage tank, they can provide extremely quick heat delivery and are usually cheaper than tank water heaters. However, because they don’t store the water, they require a bit more maintenance to keep running well.

Tank water heaters, on the other hand, store the water in a tank and heat it using electricity. Because there’s a storage tank, they’re more expensive than tankless heaters but they’re much easier to maintain. Because they have a tank, they are usually the most expensive option.

The main advantages of electric water heaters are their affordability, reliability, and ease of installation.

Pros of Electric Water Heaters

1. Affordability

Electric water heaters are among the most affordable options for heating your home with hot water. They are also relatively inexpensive to purchase and install.

Here are the top three cons of electric water heaters that you should know before buying one.

Gas Water Heaters

Gas water heaters are also known as natural gas water heaters, natural gas fired water heaters, or propane water heaters. They are basically a large tank of water that has a burner at the bottom to heat the water. The gas is piped directly to the burner to heat the water. The gas is piped into the water heater and then heated up by the burner. The gas is then released into the atmosphere.

3. Expensive Maintenance

Even though gas water heaters are very energy efficient, they require high maintenance. Because gas is used as the heat source, it’s important to keep the water filter clean. You will also need to regularly clean the burner and burners.
