What Causes Tankless Water Heaters To Break?

Tankless water heaters are built to outlast their standard counterparts and have a reputation for improved durability. However, you can still expect that yours will need repairs occasionally throughout its lifespan.

Signs your tankless water heater needs repair include: 

  • Scale buildup: Hard water can cause minerals to accumulate in the heater. This buildup can reduce efficiency and potentially lead to the unit overheating and failing.
  • System overuse: Tankless water heaters are sized for specific flow rates. If a unit is too small for the demand placed on it, it can wear out faster due to constant use.
  • Lack of maintenance: Failing to perform routine maintenance, such as flushing the system to remove sediment or checking the condition of filters and vents, can lead to premature breakdowns.
  • Component failure: Parts such as the thermostat, heating element, or ignition system can fail due to normal wear and tear or defects.
  • Venting problems: Poor ventilation can lead to an unsafe operating condition and cause the system to shut down. This is particularly crucial for gas-powered units, which need to vent out combustion gasses properly.
  • Water quality: Poor water quality can damage the water heater’s internal components, leading to malfunctions and a shorter lifespan.

The highly skilled technicians at Donley A/C & Plumbing will help diagnose the problem quickly to ensure your tankless water heater is operating efficiently again in no time.

Tankless Water Heaters vs. Standard Water Heaters

A tankless system is a great upgrade when considering a water heater for your home. While a standard tank system heats and stores water for use in the future, a tankless water heater heats water on demand as soon as you turn on your faucet.

This results in some excellent benefits, including:

  • Unlimited hot water: Unlike a tank system, which runs out of hot water when the tank is empty, a tankless system offers unlimited hot water for all your daily tasks.
  • Energy efficiency: A tankless system only heats water when you need it, which means there’s far less energy wasted in keeping a tank full of water hot.
  • Space-saving design: While standard water heaters need significant space for a large tank, a tankless system needs minimal wall space to be mounted in your garage or basement.
  • Longer lifespan: With proper maintenance, a tankless system can last up to 20 years, compared to a standard system that lasts 10 to 15 years.

Frequently Asked Questions

Why did my water heater suddenly stop working?

Water heaters can work well until there’s a serious problem. It’s possible to have an underlying issue with the system and not know until a repair or replacement is needed.

Why should I switch to a tankless water heater?

Tankless water heaters take up much less space than traditional tank-style water heaters. They also provide energy efficiency, as they only run when hot water is needed.

How long should my water heater last?

Typically, a water heater will last 10 years or more. Regular maintenance and flushing of the system can also help extend its lifespan.
