How to prepare your water heater for winter

Winter brings higher demand for hot water and can expose weak spots in your home’s heating systems. A ready water heater helps maintain comfort and efficiency through the cold season.

Step 1: Check thermostat settings and safety

Set the thermostat to a safe, energy-efficient temperature—typically around 120°F (49°C). This minimizes energy use and reduces the risk of scalding. If you have a tank with a display or digital control, verify the current setting against manufacturer recommendations and adjust if needed.

Inspect the unit for signs of wear, corrosion, or unusual noises. If you notice any leaks, rust, or persistent dripping, schedule a professional inspection before winter peaks.
