Common Causes of Water Heater Repair

Home | Blog | Published on March 20th, 2015

Water heaters are pretty robust systems, and not prone to frequent breakdowns. However, that does not mean that they are immune from all problems and repair needs. A water heater heats water for your home, but when it malfunctions, you may be left with cold water instead of hot. Prompt repair services can fix issues quickly to restore hot water and prevent the inconvenience of cold water. Water heaters are vulnerable to a number of different problems, each capable of inflicting various levels of damage. For instance, sediment buildup inside a water heater can cause loud popping noises as the pressure inside the tank changes. Let’s take a look at some of the common causes of water heater repair, and how you can prevent them by watching for early heating system issues.

What are the most frequent causes that lead to water heater repair?

Water heater repairs most often stem from rust corrosion, which can compromise the tank once the sacrificial anode rod is worn; uneven or insufficient hot water, often due to circulator pump failure or heating issues and general wear that requires annual inspection to catch issues early.

Introduction to Water Heaters

Water heaters play a vital role in every household, delivering the hot water needed for daily activities like bathing, cleaning, and cooking. With so many options available, choosing the right water heater installation can feel overwhelming. At Comfort Flow Heating, we take the guesswork out of the process by offering expert water heater installation, repair, water heater installations, and maintenance services. Our skilled technicians are dedicated to providing hot water solutions that are both reliable and energy efficient, ensuring you enjoy continuous hot water whenever you need it. If you notice issues with your system, having your water heater repaired promptly is essential to maintain a steady supply of hot water.

Choosing a new water heater involves evaluating energy efficiency, ventilation type, and installation costs. When the average water heater reaches the end of its lifespan—typically around 8 to 13 years—it’s important to replace it or consider water heater replacement to avoid unexpected breakdowns. Whether you’re interested in upgrading to a tankless water heater for improved energy efficiency or need a new storage tank water heater installed, our professional team is here to help. Conventional water heaters store and heat water in a tank, while tankless heaters provide on-demand hot water, offering space savings and greater energy efficiency. Maintaining a consistent supply of warm water not only adds comfort but also helps reduce energy costs. We pride ourselves on exceptional service and a commitment to meeting your home’s unique hot water needs.

Types of Water Heaters

When it comes to water heaters, there are several types to consider, each offering distinct advantages. Electric water heaters are a popular choice for their straightforward installation and ability to efficiently heat water using electricity. These units use heating elements to warm the water inside the tank, making them reliable and easy to maintain. Gas water heaters, powered by natural gas, are known for their energy efficiency and quick recovery times, making them ideal for households with high hot water demand.

Conventional storage water heaters are the most common type found in homes. These traditional tank models store heated water in an insulated reservoir, ensuring a ready supply of hot water is always available. They come in various capacity options and can operate on different fuel sources, including electricity, natural gas, propane, and fuel oil. Proper cooling and temperature regulation are important for maximizing efficiency and extending the lifespan of these systems. Heat pump water heaters are another energy-efficient option, using heat pump technology to transfer heat from the air to the water, which can significantly reduce energy consumption compared to standard electric models.

Tankless water heaters provide hot water on demand without the need for a storage tank, offering energy savings and continuous hot water for your home. When you turn on the hot water tap, tankless systems instantly heat water as it flows through the unit, eliminating standby heat loss and ensuring you get hot water exactly when you need it. Tankless water heaters heat water on demand and do not store any water.

Our experienced team can help you navigate the different types of water heaters, from tank water heaters to tankless models, and recommend the right water heater based on your household’s needs, energy efficiency goals, and budget. Whether you’re looking to install, repair, or maintain your water heater, we have the expertise to ensure your system delivers reliable hot water year-round.

Water Heater Components

A water heater is made up of several essential components that work together to deliver hot water throughout your home. The storage tank is the heart of most water heaters, holding the heated water until you need it. Inside the tank, the heating element (or burner in gas models) is responsible for heating the water to your desired temperature. The thermostat monitors and regulates the water temperature, ensuring your hot water is always just right. Another critical part is the temperature and pressure relief valve, which acts as a safety feature to prevent the tank from overheating or building up excessive pressure. Proper water heater installation is crucial to ensure all these components are correctly installed and functioning safely. In Portland, professional installation and regular maintenance help keep your water heater running efficiently, providing reliable hot water for your daily needs.

Rust

Any system that regularly deals with water is going to risk oxidization. That is especially true for water heaters, which are often exposed to water 24/7. Rust can cause various parts of the water heater to fail, and can even cause the tank to rupture. Tankless water heaters do not store water, so their risk of rust is slightly lessened. For tank water heaters, however, slightly stronger countermeasures are required. The following signs may indicate a failing water heater: trouble heating up, rusty water, and loud unusual noises.

Tank water heaters are equipped with devices called “sacrificial anode rods.” These are long, metal rods that are inserted into the tank, and protect the lining of the tank by rusting away themselves. Once the anode rods are completely degraded, however, the tank lining will once again be vulnerable to rust. The best way to stop this from happening is by checking your anode rod at least once a year, and replacing it if necessary. If you don’t know how to check your anode rod, call a professional to help you, ideally one who offers complete heating system services. Regular maintenance helps extend the life of your water heater and keeps it working smoothly and efficiently. If you don’t know how to check your anode rod, call a professional to help you.

Uneven Heat

If you have a lot of people using hot water at once in your house, it is very possible to simply exhaust the supply of hot water on hand. When that happens, you just have to wait for more. However, there is a difference between that and a water heater that is seemingly unable to provide consistently hot water regardless of the situation. If that is happening, you could have a number of different problems. An issue with the heater’s circulator pump could be preventing the hot water from reaching you. However, it is also possible that the heater itself is having trouble heating the water. That’s a more serious issue, and one that you’ll need a professional technician to diagnose. Most water heaters have a lifespan of about 8 to 12 years, after which they may require replacement. The best way to prevent these kinds of problems is simply to have your water heater inspected at least once a year by a professional, ideally timed with seasonal heating maintenance services.

Water Heater Maintenance

Keeping your water heater in top condition requires regular maintenance, which can help you avoid unexpected repairs and extend the life of your system. Essential maintenance tasks include checking the temperature and pressure relief valve, inspecting the anode rod for signs of corrosion, and flushing the storage tank to remove sediment buildup. Over time, mineral deposits and sediment can accumulate inside the tank, reducing efficiency and potentially causing leaks or other damage. In the Portland area, hard water can accelerate sediment buildup, making annual water heater maintenance even more important. By having your water heater serviced by a professional, you can ensure continuous hot water, prevent issues like leaking tanks, and maintain energy efficiency. Regular maintenance not only protects your investment but also helps you avoid costly repairs down the road.

Water Heater Troubleshooting

If your water heater isn’t providing hot water as expected, there are a few troubleshooting steps you can try before calling for professional water heater repair. Start by checking the thermostat to make sure it’s set to the correct temperature. For electric water heaters, verify that the circuit breaker hasn’t tripped or a fuse hasn’t blown. If you have a gas water heater, ensure the pilot light is lit and functioning properly. If these basic checks don’t resolve the issue, you may be dealing with a more serious problem such as a broken heating element, a faulty thermostat, or a leaking storage tank. Addressing these issues promptly is important to prevent water damage and restore reliable hot water to your home.

Frequently Asked Questions

Question: What are the most common causes of water heater repairs according to Comfort Flow Heating?
Answer: Comfort Flow highlights two major issues: rust, especially in tank-style heaters when the sacrificial anode rod degrades, and uneven heat, which may signal problems like a failing circulator pump or a deeper heating issue that requires professional diagnosis.

Question: How does rust develop inside a water heater, and how can it be prevented?
Answer: Rust arises from constant water exposure. In traditional tank heaters, a sacrificial anode rod protects the tank lining by corroding instead of the tank itself. Checking and replacing this rod annually helps prevent tank rust and potential rupture.

Question: What leads to uneven hot water delivery in a water heater?
Answer: Uneven heat delivery may occur if demand exceeds capacity, like during simultaneous high usage. But if the heater consistently fails to produce consistent hot water, it could indicate a malfunctioning circulator pump or a deeper heater issue needing professional evaluation.

Question: How often should water heaters be professionally inspected?
Answer: A professional annual inspection is recommended to uncover issues early—be it rust, heating inefficiencies, or component failures—and to ensure safe and consistent performance.
