Q: How do hot water heater expansion tanks work?

• <div><p>When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.</p><p>In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.</p></div>

Q: How long does it take to install a new water heater?

• <div><p>Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.</p></div>

Q: What type of water heater is best for my home?

• <div><p>You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more <a href="https://www.angi.com/articles/types-of-water-heaters.htm">common types of water heaters</a> are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system. </p></div>

Q: Should I get a tankless water heater?

• <div><p>Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. <a href="https://www.angi.com/articles/is-a-tankless-water-heater-worth-it.htm">Is a tankless water heater worth it</a>?

This was a big job. It took them several months to get the crews out to do the work, but once they started, it all moved very quickly. They had to do some extra work because of water damage discovered when they removed the old siding, but the charge for repairs was lower than expected.

Water Heaters questions, answered by experts

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.
