Signs Your Water Heater May Need Replacing
Ignoring the early warning signs of a failing water heater can lead to unexpected breakdowns and potential water damage. Be aware of these common indicators that your unit might be nearing the end of its lifespan:
- Lack of Hot Water: The most obvious sign is a complete loss of hot water or inconsistent temperatures that don't last.
- Rusty or Discolored Water: If the hot water coming from your faucets has a reddish or rusty tint, it could indicate corrosion inside the tank. This is a strong sign that the tank's integrity is compromised.
- Unusual Noises: As sediment builds up in the tank, your water heater may start making strange rumbling, popping, or cracking sounds when heating water. This sediment buildup reduces efficiency and can damage the tank.
- Leaking Tank: Any water pooling around the base of your water heater tank is a serious issue. Leaks often indicate cracks in the tank itself, which are typically not repairable and require immediate replacement.
- Age of the Unit: Traditional tank-style water heaters typically last between 8 to 12 years. If your unit is within or past this age range, it's wise to start planning for replacement, even if it hasn't completely failed yet.
- Rising Energy Bills: An aging or inefficient water heater has to work harder to heat water, leading to higher energy consumption and increased utility costs. If you notice unexplained spikes in your gas or electricity bills, the water heater could be the culprit.
If you observe any of these signs, it's time to have a professional assess your system. Ignoring these warnings could result in a sudden breakdown, leaving you without hot water when you need it most. Contact Roadrunner Plumbing & Air for expert evaluation.

Repair or Replace? Making the Right Choice
When your water heater encounters issues, the first question is often whether to repair it or opt for a full replacement. While water heater repairs can sometimes extend the life of a unit, replacement is often the more economical and practical solution in the long run, especially under certain circumstances. Consider these factors:
- Age: If your water heater is older than 10-12 years, replacement is generally recommended. Older units are less energy-efficient and more prone to frequent, costly breakdowns.
- Cost of Repair: If the cost of repairing a major component (like the tank itself, significant leaks, or multiple parts) approaches half the cost of a new unit, replacement offers better value and peace of mind.
- Frequency of Breakdowns: A water heater that requires frequent repairs is a sign of systemic issues. Investing in a new, reliable unit will save you money and frustration over time.
- Energy Efficiency: Newer water heaters, especially tankless models or high-efficiency tank models, are significantly more energy-efficient than older units. Replacing your old unit can lead to noticeable savings on your energy bills.
- Severity of the Problem: Certain problems, like a leaking tank or significant internal corrosion, are usually irreparable and require replacement.
Roadrunner Plumbing & Air technicians can help you evaluate the condition of your current water heater, discuss the pros and cons of repair versus replacement based on your specific situation, and provide an honest recommendation.
Choosing the Right Water Heater for Your San Antonio Home
Replacing your water heater offers an opportunity to upgrade to a unit that better fits your home's needs and potentially saves you money on energy costs. The primary decision is usually between a traditional tank-style heater and a tankless (on-demand) system.
- Traditional Tank Water Heaters: These units store and pre-heat a large volume of water in a tank. They have a lower upfront cost and are generally simpler to install as a direct replacement for an existing tank unit. However, they can be less energy-efficient as they constantly heat water, and you can run out of hot water if demand exceeds the tank's capacity.
- Tankless Water Heaters: These systems heat water only when it's needed, providing an endless supply of hot water on demand. They are highly energy-efficient because they don't store and constantly heat water. Tankless units also have a longer lifespan than tank heaters. Their upfront cost is higher, and installation may require modifications to gas lines, venting, or electrical connections, potentially adding to the overall project cost.
Both tank and tankless units come in natural gas and electric models. The best choice for your San Antonio home depends on factors like your household's hot water needs, available fuel sources, budget, and energy efficiency goals. Our experts at Roadrunner Plumbing & Air can assess your needs and recommend the ideal type and size of water heater.
