How to Prepare a Water Heater for Winter
Because this is not the season to be stuck without hot water, take time to properly prepare your water heater for winter. The water heater’s typically the most frequently replaced major appliance in the house. Many last less than 10 years. One of the things that can help extend water heater service life is seasonal maintenance. Here are some suggestions to prepare a water heater for winter and ensure you have plenty of hot water for the cold weather to come.
- Set the water heater thermostat to 120 degrees. Temperatures higher than that pose a danger of scalding and don’t get hot water to you any faster when the pipes in the house are cold, anyhow. Also, the higher the temperature of water inside the water heater tank, the quicker it loses heat while on stand-by—particularly during winter if the water heater is located in a cooler location like a garage or utility area. Rapid tank heat loss means the water heater cycles on and off more frequently to compensate, consuming more gas and increasing operating costs.
- Insulate exposed sections of cold and hot water pipes. Buy slip-on foam pipe insulation at a home center and place it anywhere you can reach the cold water supply line leading to the water heater and the hot water line leading away from the heater. Also, any other accessible segments of hot water pipe elsewhere in the house should be insulated, as well. This prevents freezing in winter and aids water heater performance by reducing heat loss.
- Drain and flush. Mineral sediment present in the water supply accumulates inside water heaters. It’s a major cause of higher water heating costs and shorter water heater life expectancy. A qualified professional plumber can drain the heater tank, flush out sediment accumulation, as well as verify proper function of the temperature and pressure relief (TPR) valve, an important water heater safety check.
