When was the last time you thought about your water heater? If you’re like most people, probably never. They’re out of sight, they’re doing what they were designed to do, so they end up being out of mind. But if you’re looking for a water heater that’s more energy-efficient, it might be time to give your current water heating system a serious upgrade.

Tankless water heaters are the preferred choice in energy-efficient homes. Unlike traditional tank-style heaters, which continuously use energy in order to maintain a supply of hot water, tankless water heaters use less energy. They heat water only as they’re needed. If you want to save hundreds of dollars every year, going for a tankless water heater is the smart option.

Here are five advantages of buying a tankless water heater:

• They’re long-lasting: One of the best advantages of a tankless water heater is that they last longer. A typical tank-style water heater will last an average of 10 years, while tankless units are known to last twice as long. Because tankless water heaters have replaceable parts, you won’t have to buy a brand-new unit every 10 years or so.
• They produce an endless supply of hot water: Traditional heating systems can produce only a limited supply of hot water. Their supply is limited by the size of the tank -- you might even have experienced the “surprise” rush of cold water in the morning after the hot water ran out! Tankless water heaters can give you an endless supply of hot water because they only heat water when you turn on the hot water tap. It works by allowing water to travel into the water heater unit, where the cold water is then heated by fuel or energy.
• They conserve energy: In tank-type water heaters, as soon as the water inside the tank begins to lose heat, the water heater has to constantly turn on and off just to keep the water hot at all times. With tankless units, water is heated only when you need hot water. This makes them more energy-efficient, and in turn, lowers your electricity bill.
• They have a reduced environmental impact: Tankless water heaters don’t only use less energy, but they’re also repairable. Unlike tank-type heaters, tankless units have parts that are easily replaced. You won’t have to throw away your entire unit just because a small part of it is damaged.
• They take up less space: Smaller homes will love tankless water heaters. They’re significantly more compact than traditional bulky models. To give you an idea, typical 40-gallon tank-style heaters are around 60 inches tall. Unlike gigantic tanks that waste a lot of space, tankless heaters are usually mounted on walls or placed in inconspicuous spaces. You’ll have more freed-up space on the ground for the rest of your appliances.

The Bottom Line

Tankless water heaters have more benefits than tank-style water heaters. They use less energy (therefore saving you money), provide an endless supply of warm water, take up less space, and best of all, they last longer. Although you have to spend more upfront, tankless water heaters will cost less in repairs in the long run.

If you always find yourself running out of hot water, having less floor space, and spending more than you ever imagined just to avoid cold showers, then a tankless water heater is right for you.
