When most people think of water heater problems, they picture cold showers in the winter—not scorching summer days. But the truth is, summer can be one of the hardest seasons for your water heater in Murrieta. From increased demand to mineral buildup, the warmer months can push your water heater to its limits.

If you’re a homeowner wondering why your system is acting up, this guide will break down the most common summer stressors—and how to stay ahead of them. And if you need fast, expert service, Prestige Plumbing is your go-to for water heater repair in Murrieta, CA.

1. Increased Water Usage

Summertime often means house guests, kids home from school, more laundry, and longer showers. This boost in daily water use places more demand on your water heater. Over time, the extra wear and tear can lead to reduced efficiency, inconsistent temperatures, or total system failure.

Tip: If you’ve noticed your hot water running out faster than usual, it may be time for a tune-up or flush. A licensed plumber in Murrieta, CA can check for sediment buildup or early signs of component wear.

2. Hard Water + Heat = Trouble

Murrieta has notoriously hard water, packed with minerals like calcium and magnesium. In the summer, heat can accelerate the rate at which these minerals separate and settle at the bottom of your tank.

This sediment buildup creates a barrier between the burner and the water, forcing your unit to work harder and less efficiently. The result? Lukewarm showers, higher energy bills, and premature failure.

3. Solar Heat Raises Incoming Water Temp—And That’s Not Always Good

Believe it or not, hotter incoming water can mess with your water heater’s thermostat. In some cases, it causes your system to short-cycle (heating water unnecessarily) or operate less efficiently due to confused temperature readings.

This fluctuation can affect both traditional tank water heaters and tankless units, making it more difficult to maintain consistent temperatures.

4. Expansion and Pressure Stress

High temperatures in Murrieta can cause increased water expansion inside your tank. If your temperature and pressure (T&P) relief valve isn’t working properly—or if your expansion tank is faulty—this extra pressure can damage your water heater.

Left unchecked, this can lead to leaks, overheating, or worse, a ruptured tank.

Tip: Annual inspections, especially before summer, help ensure your pressure valves are working safely.

5. Outdoor Units and Garage Installations Heat Up Fast

Many Murrieta homes have water heaters installed in the garage or even outdoors. In summer, those spaces can heat up quickly, affecting your water heater’s performance.

Excessive heat can warp parts, stress electrical components, and in the case of tankless water heaters, cause thermal lockouts.
