Understanding Your Water Heater
Before we delve into maintenance tasks, it’s essential to understand the basic workings of your water heater. There are primarily two types: traditional tank-style heaters and tankless heaters.
Traditional tank-style heaters store and heat water in a large insulated tank, typically made of steel or glass-lined steel. A heating element (electric) or burner (gas) heats the water to the desired temperature, which is controlled by a thermostat. Tank-style heaters also feature a pressure relief valve for safety and an inlet/outlet for water supply.
On the other hand, tankless water heaters, also known as on-demand water heaters, heat water directly without the use of a storage tank. When hot water is needed, cold water travels through a pipe into the unit, where it is heated by either a gas burner or an electric element. Tankless heaters provide a continuous supply of hot water but may have lower flow rates compared to tank-style heaters.
Regardless of the type, all water heaters consist of several key components, including a heating element (electric) or burner (gas), a thermostat to control water temperature, a pressure relief valve for safety, and an inlet/outlet for water supply. Understanding these components will help you identify potential issues and perform maintenance tasks more effectively.
Common issues affecting water heaters include sediment buildup, corrosion of the tank or heating elements, faulty thermostats, and leaks. Regular maintenance can prevent many of these problems and ensure your water heater operates efficiently for years to come.
