The Truth About Hot Water Heater Efficiency: Debunking Common Misconceptions

Separating Fact from Fiction: Hot Water Heater Efficiency

At Aqua Plumbing & Air, we often encounter misconceptions about hot water heaters and their efficiency. Today, we’re going to debunk a common myth that many homeowners believe:

Myth: Keeping your water heater temperature set high saves energy in the long run

This myth suggests that maintaining a higher temperature in your water heater is more efficient because it reduces the need for frequent reheating. However, this couldn’t be further from the truth!

The Reality:

Setting your water heater to a higher temperature actually wastes energy and increases your utility bills. Here’s why:

  • Higher temperatures lead to more standby heat loss
  • You’ll likely mix more cold water with the hot water to achieve a comfortable temperature
  • There’s an increased risk of scalding

The Solution:

For optimal efficiency and safety, we recommend setting your water heater temperature to 120°F (49°C). This temperature is hot enough for most household needs while minimizing energy waste and reducing the risk of scalding.

By debunking this myth, we hope to help our customers make informed decisions about their hot water heater usage. Remember, Aqua Plumbing & Air is always here to provide dependable HVAC, electrical, and plumbing services to ensure your home systems are running efficiently and safely.
