5 Signs You Need a New Water Heater in San Antonio

San Antonio’s rapidly fluctuating temperatures can be a test for any water heater. This article outlines the signs that your water heater might be crying out for a replacement, and why a new water heater is a good choice.

Key Takeaways:

  • Recognizing the signs of a failing water heater early can save you from costly repairs in the future.
  • A tankless water heater will improve energy efficiency and provide unlimited hot water.
  • Professionals know exactly what they are looking for and can provide insight into your situation.

Does Your Water Heater Need Replacing?

Your water heater may be signaling its end. Look out for these red flags to know when it’s time to contact professionals in San Antonio for a new water heater.

The Water Looks Cloudy or Rusty

When your water starts to appear cloudy or has a rusty tint, it’s a clear sign that the inside of your old water heater is breaking down. This deterioration is often a result of sediment build-up or rust forming inside the tank, which is common in older units or those that haven’t been maintained regularly. This sediment can cause your water heater to work harder to heat water, raising your energy bills.

The presence of rust and sediment in your water can pose health concerns. While small amounts of rust and sediment are not typically harmful, larger quantities or prolonged exposure could potentially be hazardous, especially to individuals with certain sensitivities or health conditions.

Water Heater is Leaking

A leaking water heater is not a situation to be taken lightly, as it’s a clear indication of internal damage. This could be due to issues with the tank itself or the plumbing connections. Both require immediate attention to prevent further complications.

The root cause of the leak could vary, it might be a result of corrosion that has eaten through the tank wall, faulty connections, or even a high level of water pressure that the tank can no longer withstand.

Leaks can quickly escalate, leading to a significant amount of water loss which could show as increased utility bills. The water escaping from the unit could cause big-time water damage to your home, especially if the water heater is located in a crawl space or basement. This water accumulation could also lead to mold growth and structural damage.

Modern water heaters, including tankless options, come with enhanced features to reduce the risks of leaks, with corrosion-resistant materials and improved design to handle water pressure effectively.

Water Doesn’t Get Hot

Experiencing cold or lukewarm water despite adjusting the temperature is a common symptom of a failing heating element in your water heater. This is a clear sign that your water heater is not operating as it should and needs inspection by service experts.

The heating element is key for raising the water temperature to the desired level. When it’s failing it can no longer heat the water adequately, affecting your daily routines like showers, cleaning, and cooking. This could come from a variety of factors such as electrical problems, a burnt-out element, or even a faulty thermostat.

In some cases, this problem could be resolved by simply repairing or replacing the faulty part. However, if the issue is persistent or if other parts of the water heater are also showing signs of wear and tear, it might be more cost-effective to replace the entire unit.

It’s important to address this issue quickly as a malfunctioning water heater could be consuming unnecessary energy, driving up your utility bills without providing the hot water you need.

Water Heater is Older Than 15 Years

The age of a water heater impacts its efficiency and performance. Water heaters have a lifespan of 10 to 15 years. If your unit is in or beyond this age range, it’s likely operating at reduced efficiency, which means it’s using more electricity or gas to deliver the needed amount of hot water. This could be silently increasing your energy bills over time.

Older water heaters are not just inefficient, they are also prone to developing issues such as leaks, rust, and sediment buildup, which can further degrade their performance and potentially lead to costly water damage in your home. As water heaters age, the availability of replacement parts can become scarce, and repairs can become more expensive.

Upgrading to a new, energy-efficient tankless water heater can be a smart investment. Tankless water heaters heat water only when it’s needed, which results in big energy savings. Unlike traditional tank water heaters, they don’t store hot water, eliminating the energy losses associated with keeping a tank of water heated.

The latest models of tankless water heaters are equipped with advanced features such as digital temperature controls, self-modulating technology, and built-in leak detection systems, enhancing their performance, safety, and user-friendliness.

Constant Repairs Needed

If you find yourself frequently scheduling repairs, it might be more economical to replace the unit. A new water heater installation may be in the cards for you. Here are some common water heater repairs we run into:

  • Heating Element Failure: Causes no hot water or insufficient heating.
  • Thermostat Problems: Leads to incorrect water temperatures.
  • Pilot Light Outage (Gas Water Heaters): Prevents the heater from functioning.
  • Gas Valve Issues (Gas Water Heaters): Hinders the heating process.
  • Pressure Relief Valve Malfunction: Potential safety hazard with excess pressure.
  • Leakage: From tank or plumbing, causing water damage and efficiency loss.
  • Sediment Build-up: Reduces efficiency and lifespan.
  • Corrosion and Rust: Lead to leaks or cloudy, discolored water.
  • Noise Issues: Indicates sediment build-up or other internal problems.
  • Drain Valve Issues: Affects tank flushing and may lead to leaks.
  • Anode Rod Deterioration: Requires replacement to maintain tank integrity.
  • Improper Venting (Gas Water Heaters): Causes operational and safety issues.
