5 Star Plumbing > Blog > Gas Water Heater Repair vs. Replacement: Which is the Better Option?

Whether your gas water heater requires repair again or you’re considering an upgrade, deciding between fixing and replacing can be difficult. In this article, we’ll discuss the types of gas and tankless water heaters, their components, installation considerations, repair issues, efficiency factors, and tips to help determine whether to repair or replace your unit. Read on to navigate this important decision.

Understanding Water Heaters

  1. Types of Water Heaters

Traditional tank-based gas water heaters have been a popular choice for decades thanks to their wide range of capacities, energy efficiency, and ability to provide hot water to the entire household. Tankless units are gaining in popularity due to their compact size, energy savings, and continuous flow of hot water on demand. Weighing the pros and cons of each is key.

  1. Components of Water Heaters

Gas water heaters contain key components like a hot water tank, gas-powered heating elements, a pilot light for ignition, thermostats to control water temperature, a cold water inlet and hot water outlet. Proper functioning and maintenance of parts like the water heater element wrench, drain valve, gas control valve, and pressure relief valve impact performance and safety.

Making the Decision: Repair or Replace?

Signs Your Gas Water Heater Needs Replacement, Not Just Repair

Identifying when a gas water heater requires replacement instead of repair is crucial in avoiding unnecessary expenses and ensuring consistent hot water supply. Here are key indicators that point towards the need for a water heater replacement:

  1. Age of the Water Heater Tank: Gas water heaters typically have a lifespan of about 8-12 years. If your unit is nearing or has surpassed this age range, it’s often more cost-effective to replace it rather than paying for frequent repairs.

  2. Frequent Tripping of the Circuit Breaker: If your water heater’s circuit breaker trips repeatedly, it could indicate a fundamental electrical issue that might be irreparable, signaling the need for a replacement.

  3. Reset Button is Constantly Engaged: Regularly having to press the reset button on your water heater suggests internal failures. Persistent use of the reset button is a clear sign that the unit is failing.

  4. Issues with the Upper Thermostat: A malfunctioning upper thermostat that fails to regulate water temperature accurately is a sign of systemic issues within the heater. If recalibration by a professional plumber doesn’t resolve the problem, replacement may be necessary.

  5. Lukewarm Water despite Full Heating: If your hot water faucet consistently delivers lukewarm water despite the heater working at full capacity, it might indicate serious issues with the heating elements or gas supply.

  6. Visible Rust and Corrosion: If you notice rust either in the water or on the tank itself, it’s a strong indicator that the integrity of the tank is compromised. Rust and corrosion are irreversible and warrant a replacement.

  7. Water Heater Leaks: Leaks around the water heater, especially if coming from the tank, often cannot be effectively repaired and suggest that the tank’s structure has been compromised.

  8. High Replacement Cost vs. Repair Cost: If the cost of repairing your gas water heater, including parts like faulty thermostats or high-temperature cutoffs, approaches or exceeds 50% of the cost of a new heater, replacement is a more economically sound decision.

  9. Inconsistent Water Supply and Pressure: Problems with water supply and pressure, especially if related to the water heater, such as fluctuating temperatures or weak flow, can indicate systemic failures that repair might not fix.

  10. Inefficiency and Increased Gas Bills: An old water heater that requires more gas to heat water is an inefficient unit. If your bills have increased without a corresponding increase in usage, consider a replacement.

  11. Recommendation from Authorized Service Providers: A professional plumber or technician from a gas utility company or authorized service provider may advise replacement after assessing the unit. Their expert opinion should be a critical factor in your decision-making process.

  12. Availability of Modern, Efficient Models: Advancements in technology mean newer models are more energy-efficient and reliable. If your current unit is old and inefficient, upgrading to a newer model from a reputable brand can be a wise investment.

While hot water heater repair might seem like an immediate solution, recognizing these signs can save you from continuous repair costs and inconvenience. Consulting with a gas company or professional plumber can provide you with a clearer understanding of whether repair or replacement is the best course of action for your specific situation.
