Does Your Tankless Water Heater Need To Be Replaced?

Here’s How To Tell If It’s Time To Go About Replacing A Water Heater

Nothing lasts forever, and unfortunately for homeowners, those hundreds of dollars they spend on a water heater can only buy them so much time. With daily use, water heaters will wear down and show signs that they need to be replaced. To help homeowners figure out when that time has come, here are a few of the most common signs that a water heater has reached the end of its lifespan.

Concerning Water Heater Corrosion

old water heater Corrosion occurs when a material—usually something metal—reacts with another substance, such as water, hydrogen, oxygen, or certain salts and acids. When this happens, rust is formed, which can compromise the strength and integrity of that material. Since water heaters are made to contain and even facilitate the flow of water, they are expected to have their fair share of corrosion, a process that is slowed down significantly by the presence of an anode rod.

Eventually, the anode rod succumbs to corrosion and becomes depleted, allowing rust to make its way to the water flowing out of fixtures around the house. This, along with discolored water that is accompanied by a faint metallic odor, are signs that the water heater in question could be due for a replacement. 

Inability To Produce Hot Water

After all, no one wants to endure tepid baths or cold showers, and neither would they want to step into a stream of warm water only to be left shivering when the hot water supply quickly runs out. While it is possible to investigate the cause of the problem and come up with a fix, homeowners should also weigh on whether the cost of this particular water heater repair is more expensive than going for a new unit that will likely need fewer fixes or maintenance moving forward.

Nearing the End of a Tankless Water Heater Lifespan

Tankless water heaters are a newer invention than the original storage tank water heater that is more widely used in most homes, but they are by no means made of lesser quality. Tankless water heaters have a longer life expectancy than traditional water heaters, which are expected to last 10-15 years. In contrast, a tankless water heater’s lifespan is about 5 years longer or more.

Homeowners who have units about a decade or two old may want to start considering getting a replacement, especially if its age shows through observable wear and tear. Older heaters that are not well-maintained are also more prone to frequent breakdowns, so it might be wise to consider if the accumulated cost of so many repairs may be costing homeowners more than just replacing the old unit with a new one.

A Guide to Tankless Water Heaters

When households want to reduce their energy bills, save space, and have hot water when needed (eliminating waiting for the water tank to heat up between showers), tankless water heaters can be their home’s best water heating solution. This guide will share what tankless water heaters are, how they work, and the benefits of installing them in homes.

What Is a Tankless Water Heater?

While traditional storage water heaters have a large tank to provide hot water to a household, with tankless hot water heaters, the water is heated as it passes through the system and only as needed.

Because they only heat water when needed instead of continuously heating a large tank of water, tankless water heaters can be more energy efficient than traditional storage water heaters. Additionally, their heating water on demand and the lack of a storage tank allow tankless water heaters to not run out of hot water like storage water heaters do when the hot water in the tank runs out.

How Does a Tankless Water Heater Work?

  • When a faucet or showerhead is turned on and hot water is requested, cold water enters the tankless water heater through an inlet pipe.
  • Inside the unit, the heat exchanger quickly heats the incoming cold water as it flows through.
  • The tankless water heater uses a flow sensor to detect the water flow rate and a temperature sensor to measure the incoming water temperature. Based on these readings, the heater adjusts the heating elements or gas burner to achieve the desired hot water temperature.
  • Since these systems heat water as it flows through the unit, they can provide a continuous supply of hot water to the household. There is no need to wait for a storage tank to refill and reheat the water.

Advantages of Tankless Water Heaters

While most households are familiar with storage water heater units, tankless water heaters provide many benefits to families. Some of their benefits include:

  • Energy efficiency: They are more energy-efficient than traditional storage tank water heaters by only heating water when needed and not keeping a large water tank hot.
  • Savings on utility bills: The efficiency of tankless water heaters is reflected in lower water heating costs for homeowners.
  • Space-saving: These systems are compact and can be mounted on walls, allowing homeowners to save space.
  • Longer lifespan: These systems generally have a longer lifespan than traditional storage water heaters. With proper maintenance, they can last around 20 years or more, and storage tank water heaters typically last about 10-15 years.
  • Endless hot water: Since they provide hot water on demand, there is no risk of running out of hot water, even with multiple simultaneous hot water demands in different parts of the house.
