How Tank Water Heaters Work
Tank water heaters operate by storing a large volume of hot water in a cylindrical tank. This tank continuously heats and maintains the water at a preset temperature, ready for use. When a hot water faucet is turned on, water from the top of the tank is drawn out and replaced with cold water that is heated to the desired temperature. The heating element or gas burner within the tank ensures that the water remains hot and available. This process provides a consistent supply of hot water, but can also lead to energy waste, as the water is continuously heated even when not in use. The large tank size may also require substantial space for installation. It also works with efficiency when you consider different types of water heaters that goes perfect with the climate of Baltimore.
How Tankless Water Heaters Work
Tankless water heaters, also known as on-demand water heaters, heat water directly as it flows through the unit. Instead of storing hot water, these systems use a heat exchanger to warm the water only when needed. When a hot water faucet is turned on, cold water enters the unit and is rapidly heated by either an electric element or a gas burner. This method eliminates the need for a storage tank and provides an endless supply of hot water on demand. However, the flow rate may be limited based on the unit’s capacity and the number of simultaneous hot water demands. Tankless systems are compact and can be installed in smaller spaces.
