Separating Fact from Fiction: Water Heater Efficiency

At Aqua Plumbing & Air, we’re committed to providing our customers with accurate information about their home systems. Today, we’re tackling a common myth about water heaters that many homeowners believe.

The Myth: Keeping Your Water Heater at a Constant High Temperature Saves Energy

Many people think that maintaining their water heater at a high temperature 24/7 is more energy-efficient than lowering the temperature when hot water isn’t needed. The logic behind this myth is that it takes more energy to heat cold water than to maintain already hot water.

The Truth: Lowering Your Water Heater Temperature Saves Energy and Money

In reality, lowering your water heater’s temperature when you’re not using hot water can significantly reduce energy consumption and save you money. Here’s why:

  • Heat loss: Water heaters constantly lose heat to their surroundings, even when not in use.
  • Energy consumption: Maintaining a high temperature requires continuous energy input to compensate for heat loss.
  • Efficiency: Modern water heaters are designed to heat water quickly and efficiently when needed.

Our Recommendation

To maximize energy efficiency and reduce costs:

1. Set your water heater to 120°F (49°C) for daily use.
2. Consider installing a programmable thermostat for your water heater.
3. Use a timer to lower the temperature during periods of low usage, such as overnight or when you’re away.

By debunking this myth, we hope to help our customers make informed decisions about their home’s energy usage. For more tips on improving your home’s efficiency, contact Aqua Plumbing & Air – your trusted source for dependable HVAC, electrical, and plumbing services.
