Yes, there are ways you can extend the life of your water heater. For many home owners, their water heaters have a life span of about 5 years due to lack of maintenance, but if maintained properly, a water heater can work effectively for 10 or even 20 years. Water heater tanks these days are manufactured using steel and are lined using glass or porcelain. As a result of this lining, oxidation takes place over time. Due to oxidation, deterioration takes place which may even lead to leaks.
The main reason for deterioration of water heaters is sediment build-up. However the water heater would still function properly in the short-term even if affected by sediment build-up. Hard water can accelerate this build-up. There are some ways to extend the life of your water heater, including replacement of the anode rod, expansion tank installation, cleaning the tank, install a pressure regulating valve, as well as water softener. A anode rod in good condition can help prevent the corrosion in the tank. The reason is that the anode rod is made up of either aluminum or magnesium which corrodes over time protecting the tank itself from corrosion. Installation of an expansion tank is another way to control water expansion.
When water is heated to temperatures of 100°C water expands, which can have an impact on the inner surfaces of the water heater and also on the plumbing connection of your home. This expansion effect can be controlled by installing an expansion tank. Expansion tanks can double the life of your heater. Sediment built-up can be prevented by cleaning the water heater once in a year.
This is applicable only for older water heaters since the latest models have a built-in cleaning mechanism. A pressure regulating valve helps control the pressure inside the water heater preventing it from sudden failure. Water softener can also prevent your water heater from scaling.
