The answer to 'lifespan of water heater installation' is that the typical lifespan of a water heater is 8-12 years. However, the actual lifespan can vary depending on factors like the type of water heater, the quality of installation, and how well it's maintained. With proper care and maintenance, some water heaters may last up to 15 years, while others may need to be replaced sooner.
The lifespan of a water heater is influenced by the materials used, the efficiency of the heating element, and the quality of the installation. Tankless water heaters, for example, can often last longer than traditional tank-style heaters. Regular flushing and maintenance can also help extend the lifespan of any water heater.
