The Ultimate Guide to Hot Water Systems: Lifespan, Size, and Replacement

There isn’t a one-size-fits-all answer to the average lifespan of a hot water system, every system is different, and it depends on the water quality, and regularity of maintenance. However, a gas storage hot water system, electric storage hot water system or instant electric hot water system will last between 10-15 years. On the other hand, an instant gas hot water system or solar hot water system can last up to 20 years. By regularly maintaining a hot water system, including flushing the tank, checking the pressure relief valve and replacing the anode rod, you can significantly increase the lifespan of a hot water system.

Every household is different, with differing hot water needs and usage patterns, so naturally, the size of your hot water system will be dependent on these circumstances. Usually, when purchasing a hot water system, you will need to take into consideration the number of occupants in your home, how many bathrooms you have and how many appliances you have that regularly use hot water. With this information, a professional plumber can help you to calculate the right size hot water system for your needs.
