Understanding Traditional Water Heaters

Traditional water heaters, also known as tank-type water heaters, store and heat water in a large tank. They always maintain a ready supply of hot water, meaning you can draw it from a tap whenever you need it.

Inside these tanks, heating elements or gas burners regularly warm the water to a set temperature. This ensures that hot water is available instantly—whether for your shower, dishwasher, or washing machine.

However, this constant heating results in energy wastage because the system works day and night to keep the stored water hot regardless of demand. As heat loss occurs through the tank walls over time—a phenomenon known as standby heat loss—the heater must kick in again to maintain the desired temperature.

Most traditional heaters located in basements or crawl spaces often operate unnoticed but contribute substantially to monthly energy bills due to their continuous need for power to sustain that reserve of heated water.

What is a Tankless Water Heater?

A tankless water heater, also known as an on-demand water heater, is a highly efficient system designed to provide hot water only as it is needed. Unlike traditional models with storage tanks, these units heat water directly without using a reservoir, ensuring a fresh supply whenever you turn on the tap.

How They Work

Tankless water heaters offer a modern approach to water heating. Unlike their traditional counterparts, they provide hot water on-demand without needing a storage tank.

  • When you open a hot water tap, cold water travels through a pipe into the unit.
  • The water flow triggers the heating element; this can be an electric element or a gas-powered burner.
  • Heat exchangers within the tankless heater then quickly raise the temperature of the incoming water.
  • As water passes through these exchangers, it instantly reaches your desired temperature.
  • Since there’s no storage tank, the risk of water damage from leaks is significantly reduced.
  • Energy consumption drops as these units heat water only when needed and have no standby heat loss.
  • They require proper ventilation systems to expel exhaust gases, especially in models that run on gas.
  • Gas line upgrades may be necessary to accommodate higher BTUs (British Thermal Units) that some tankless units require.
  • Systems come with safety features that prevent overheating and ensure proper operation.
  • Tankless heaters often include smart technology like WiFi compatibility for easy monitoring and control via user experience-enhancing apps.
  • Maintenance requirements include periodic vinegar flushes to remove mineral build-up caused by hard water.
