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.

Step 2: Flush and drain to remove sediment

Sediment buildup can reduce efficiency and shorten the heater’s life. Turn off the power or gas supply and attach a hose to the drain valve. Open the valve to let water flow out and then briefly flush with clean water. Repeat as needed, following your model’s instructions, and restore power once complete.

Flushing helps improve heating efficiency, lowers energy bills, and can prevent sediment-related noises. If the sediment is heavy or you’re unsure how to proceed, contact a licensed technician.

Step 3: Insulate and protect outdoor and exposed components

Install or replace an insulating blanket on electric water heaters if recommended by the manufacturer. Insulate exposed hot water pipes to reduce heat loss. If you have an outdoor unit or pipes in unheated spaces, consider additional protection such as pipe sleeves or heat tape, especially in freezing climates.

Check the anode rod (if accessible) and replace it if corroded to prevent tank decay. Look for obvious leaks around fittings and connections, and tighten or reseal as needed with appropriate sealants.

Extra tips: keep a small emergency kit for winter repairs, note your service schedule, and know the signs that indicate a professional check is needed—like rising water temperature, odd odors, or water discolouration. With these steps, you’ll reduce risk of cold showers and seasonal breakdowns.
