Water heaters are one of a homes’ most essential appliance but yet the most unappreciated. They can account for about 25% of the homes’ energy bill—so they are doing a lot of work.
Based on manufactures suggested service life is approximately 8-12 years with quality installation, a regular maintenance schedule and better water quality. Typically, in our area, most tank hot water heaters without softened water and don’t have an expansion tank last 7 years.
How often should you replace a conventional storage water heater? If it’s nearing it’s maxed out life expectancy of 10-13 years, replacement is obvious. New models are up to 20% more efficient and can save up to $700 in energy costs over the life of the unit.
Expansion tanks? Why do you need one? It absorbs built up pressure in the hot water heater and hot water supply lines. Having an expansion tank installed correctly with the water heater will increase the lifetime of the conventional water heater and water consuming appliances by reducing the build up of pressure.
