The water heater is one of the most useful household appliances. Unfortunately, many people do not realize the importance of their water heaters until harsh winter strikes and temperatures plummet.

When their water heater starts acting up many people wonder if they should repair or replace it. When deciding whether to repair or replace a water heater, one of the most important factors to consider is its age.

Regular maintenance will help prevent problems and reduce wear and tear on different water heater components, age-related deterioration is inevitable and you will have to replace your water heater after it reaches the end of its service life.

There are two types of water heaters-tank water heaters and tankless water heaters. As the name suggests, tank water heaters have storage tanks. They can store up to 40-50 gallons of water. A tank water heater constantly heats the water.

Tank water heaters are less expensive than tankless water heaters but do not last as long as their tankless counterparts. Gas water heaters usually last 10 years, whereas most electric water heaters have a lifespan of 12 years.

Internal corrosion, high water pressure, improper venting, and sediment buildup can cause a tank water heater to fail prematurely.

Unlike tank water heaters, tankless water heaters-also called on-demand water heaters, instantaneous water heaters, constant flow water heaters, instant-on water heaters, and inline water heaters do not use a storage tank. They heat water as it flows through them, providing hot water on demand.

Tankless water heaters last 20 years. Though tankless water heaters are more expensive upfront than tank water heaters, they have several advantages.

Because they do not use a hot water storage tank, these heaters require less space for installation than traditional tank water hearts and are also more energy-efficient.

With a tankless water heater, you will save on energy costs. A tankless water heater heats only as much water as needed when it is needed and can help reduce your electricity bill by 20-35 percent as compared to a traditional water heater.

Tankless water heaters need less maintenance than traditional water heaters. If you use a tank water heater, you may run out of water as your household’s entire supply is stored in the tank. With a tankless water heater, on the other hand, you will have an endless supply of hot water.

A traditional tank water heater can overheat. Water heater explosions are rare, but when they occur they are devastating. Because tankless water heaters hold very little water, they are less likely to overheat and explode.
